-# GoogleTest
-
-### Announcements
-
-#### Live at Head
-
-GoogleTest now follows the
-[Abseil Live at Head philosophy](https://abseil.io/about/philosophy#upgrade-support).
-We recommend
-[updating to the latest commit in the `main` branch as often as possible](https://github.com/abseil/abseil-cpp/blob/master/FAQ.md#what-is-live-at-head-and-how-do-i-do-it).
-
-#### Documentation Updates
-
-Our documentation is now live on GitHub Pages at
-https://google.github.io/googletest/. We recommend browsing the documentation on
-GitHub Pages rather than directly in the repository.
-
-#### Release 1.11.0
-
-[Release 1.11.0](https://github.com/google/googletest/releases/tag/release-1.11.0)
-is now available.
-
-#### Coming Soon
-
-*   We are planning to take a dependency on
-    [Abseil](https://github.com/abseil/abseil-cpp).
-*   More documentation improvements are planned.
-
-## Welcome to **GoogleTest**, Google's C++ test framework!
-
-This repository is a merger of the formerly separate GoogleTest and GoogleMock
-projects. These were so closely related that it makes sense to maintain and
-release them together.
-
-### Getting Started
-
-See the [GoogleTest User's Guide](https://google.github.io/googletest/) for
-documentation. We recommend starting with the
-[GoogleTest Primer](https://google.github.io/googletest/primer.html).
-
-More information about building GoogleTest can be found at
-[googletest/README.md](googletest/README.md).
-
-## Features
-
-*   An [xUnit](https://en.wikipedia.org/wiki/XUnit) test framework.
-*   Test discovery.
-*   A rich set of assertions.
-*   User-defined assertions.
-*   Death tests.
-*   Fatal and non-fatal failures.
-*   Value-parameterized tests.
-*   Type-parameterized tests.
-*   Various options for running the tests.
-*   XML test report generation.
-
-## Supported Platforms
-
-GoogleTest requires a codebase and compiler compliant with the C++11 standard or
-newer.
-
-The GoogleTest code is officially supported on the following platforms.
-Operating systems or tools not listed below are community-supported. For
-community-supported platforms, patches that do not complicate the code may be
-considered.
-
-If you notice any problems on your platform, please file an issue on the
-[GoogleTest GitHub Issue Tracker](https://github.com/google/googletest/issues).
-Pull requests containing fixes are welcome!
-
-### Operating Systems
-
-*   Linux
-*   macOS
-*   Windows
-
-### Compilers
-
-*   gcc 5.0+
-*   clang 5.0+
-*   MSVC 2015+
-
-**macOS users:** Xcode 9.3+ provides clang 5.0+.
-
-### Build Systems
-
-*   [Bazel](https://bazel.build/)
-*   [CMake](https://cmake.org/)
-
-**Note:** Bazel is the build system used by the team internally and in tests.
-CMake is supported on a best-effort basis and by the community.
-
-## Who Is Using GoogleTest?
-
-In addition to many internal projects at Google, GoogleTest is also used by the
-following notable projects:
-
-*   The [Chromium projects](http://www.chromium.org/) (behind the Chrome browser
-    and Chrome OS).
-*   The [LLVM](http://llvm.org/) compiler.
-*   [Protocol Buffers](https://github.com/google/protobuf), Google's data
-    interchange format.
-*   The [OpenCV](http://opencv.org/) computer vision library.

-# Googletest Mocking (gMock) Framework
-
-### Overview
-
-Google's framework for writing and using C++ mock classes. It can help you
-derive better designs of your system and write better tests.
-
-It is inspired by:
-
-*   [jMock](http://www.jmock.org/)
-*   [EasyMock](http://www.easymock.org/)
-*   [Hamcrest](http://code.google.com/p/hamcrest/)
-
-It is designed with C++'s specifics in mind.
-
-gMock:
-
--   Provides a declarative syntax for defining mocks.
--   Can define partial (hybrid) mocks, which are a cross of real and mock
-    objects.
--   Handles functions of arbitrary types and overloaded functions.
--   Comes with a rich set of matchers for validating function arguments.
--   Uses an intuitive syntax for controlling the behavior of a mock.
--   Does automatic verification of expectations (no record-and-replay needed).
--   Allows arbitrary (partial) ordering constraints on function calls to be
-    expressed.
--   Lets a user extend it by defining new matchers and actions.
--   Does not use exceptions.
--   Is easy to learn and use.
-
-Details and examples can be found here:
-
-*   [gMock for Dummies](https://google.github.io/googletest/gmock_for_dummies.html)
-*   [Legacy gMock FAQ](https://google.github.io/googletest/gmock_faq.html)
-*   [gMock Cookbook](https://google.github.io/googletest/gmock_cook_book.html)
-*   [gMock Cheat Sheet](https://google.github.io/googletest/gmock_cheat_sheet.html)
-
-GoogleMock is a part of
-[GoogleTest C++ testing framework](http://github.com/google/googletest/) and a
-subject to the same requirements.

-// Google Mock - a framework for writing C++ mock classes.
-//
-// The ACTION* family of macros can be used in a namespace scope to
-// define custom actions easily.  The syntax:
-//
-//   ACTION(name) { statements; }
-//
-// will define an action with the given name that executes the
-// statements.  The value returned by the statements will be used as
-// the return value of the action.  Inside the statements, you can
-// refer to the K-th (0-based) argument of the mock function by
-// 'argK', and refer to its type by 'argK_type'.  For example:
-//
-//   ACTION(IncrementArg1) {
-//     arg1_type temp = arg1;
-//     return ++(*temp);
-//   }
-//
-// allows you to write
-//
-//   ...WillOnce(IncrementArg1());
-//
-// You can also refer to the entire argument tuple and its type by
-// 'args' and 'args_type', and refer to the mock function type and its
-// return type by 'function_type' and 'return_type'.
-//
-// Note that you don't need to specify the types of the mock function
-// arguments.  However rest assured that your code is still type-safe:
-// you'll get a compiler error if *arg1 doesn't support the ++
-// operator, or if the type of ++(*arg1) isn't compatible with the
-// mock function's return type, for example.
-//
-// Sometimes you'll want to parameterize the action.   For that you can use
-// another macro:
-//
-//   ACTION_P(name, param_name) { statements; }
-//
-// For example:
-//
-//   ACTION_P(Add, n) { return arg0 + n; }
-//
-// will allow you to write:
-//
-//   ...WillOnce(Add(5));
-//
-// Note that you don't need to provide the type of the parameter
-// either.  If you need to reference the type of a parameter named
-// 'foo', you can write 'foo_type'.  For example, in the body of
-// ACTION_P(Add, n) above, you can write 'n_type' to refer to the type
-// of 'n'.
-//
-// We also provide ACTION_P2, ACTION_P3, ..., up to ACTION_P10 to support
-// multi-parameter actions.
-//
-// For the purpose of typing, you can view
-//
-//   ACTION_Pk(Foo, p1, ..., pk) { ... }
-//
-// as shorthand for
-//
-//   template <typename p1_type, ..., typename pk_type>
-//   FooActionPk<p1_type, ..., pk_type> Foo(p1_type p1, ..., pk_type pk) { ... }
-//
-// In particular, you can provide the template type arguments
-// explicitly when invoking Foo(), as in Foo<long, bool>(5, false);
-// although usually you can rely on the compiler to infer the types
-// for you automatically.  You can assign the result of expression
-// Foo(p1, ..., pk) to a variable of type FooActionPk<p1_type, ...,
-// pk_type>.  This can be useful when composing actions.
-//
-// You can also overload actions with different numbers of parameters:
-//
-//   ACTION_P(Plus, a) { ... }
-//   ACTION_P2(Plus, a, b) { ... }
-//
-// While it's tempting to always use the ACTION* macros when defining
-// a new action, you should also consider implementing ActionInterface
-// or using MakePolymorphicAction() instead, especially if you need to
-// use the action a lot.  While these approaches require more work,
-// they give you more control on the types of the mock function
-// arguments and the action parameters, which in general leads to
-// better compiler error messages that pay off in the long run.  They
-// also allow overloading actions based on parameter types (as opposed
-// to just based on the number of parameters).
-//
-// CAVEAT:
-//
-// ACTION*() can only be used in a namespace scope as templates cannot be
-// declared inside of a local class.
-// Users can, however, define any local functors (e.g. a lambda) that
-// can be used as actions.
-//
-// MORE INFORMATION:

-  //  *  Unlike most forwarding functions, we pass scalars through by value.
-  //     This isn't strictly necessary because an lvalue reference would work
-  //     fine too and be consistent with other non-reference types, but it's
-  //     perhaps less surprising.
-  //
-  //     For example if the mocked function has signature void(int), then it
-  //     might seem surprising for the user's initial action to need to be
-  //     convertible to Action<void(const int&)>. This is perhaps less
-  //     surprising for a non-scalar type where there may be a performance
-  //     impact, or it might even be impossible, to pass by value.
-  //
-  //  *  More surprisingly, `const T&` is often not a const reference type.
-  //     By the reference collapsing rules in C++17 [dcl.ref]/6, if T refers to
-  //     U& or U&& for some non-scalar type U, then InitialActionArgType<T> is
-  //     U&. In other words, we may hand over a non-const reference.
-  //
-  //     So for example, given some non-scalar type Obj we have the following
-  //     mappings:
-  //
-  //            T               InitialActionArgType<T>
-  //         -------            -----------------------
-  //         Obj                const Obj&
-  //         Obj&               Obj&
-  //         Obj&&              Obj&
-  //         const Obj          const Obj&
-  //         const Obj&         const Obj&
-  //         const Obj&&        const Obj&
-  //
-  //     In other words, the initial actions get a mutable view of an non-scalar
-  //     argument if and only if the mock function itself accepts a non-const
-  //     reference type. They are never given an rvalue reference to an
-  //     non-scalar type.
-  //
-  //     This situation makes sense if you imagine use with a matcher that is
-  //     designed to write through a reference. For example, if the caller wants
-  //     to fill in a reference argument and then return a canned value:
-  //
-  //         EXPECT_CALL(mock, Call)

-// Google Mock - a framework for writing C++ mock classes.
-//
-// The MATCHER* family of macros can be used in a namespace scope to
-// define custom matchers easily.
-//
-// Basic Usage
-// ===========
-//
-// The syntax
-//
-//   MATCHER(name, description_string) { statements; }
-//
-// defines a matcher with the given name that executes the statements,
-// which must return a bool to indicate if the match succeeds.  Inside
-// the statements, you can refer to the value being matched by 'arg',
-// and refer to its type by 'arg_type'.
-//
-// The description string documents what the matcher does, and is used
-// to generate the failure message when the match fails.  Since a
-// MATCHER() is usually defined in a header file shared by multiple
-// C++ source files, we require the description to be a C-string
-// literal to avoid possible side effects.  It can be empty, in which
-// case we'll use the sequence of words in the matcher name as the
-// description.
-//
-// For example:
-//
-//   MATCHER(IsEven, "") { return (arg % 2) == 0; }
-//
-// allows you to write
-//
-//   // Expects mock_foo.Bar(n) to be called where n is even.
-//   EXPECT_CALL(mock_foo, Bar(IsEven()));
-//
-// or,
-//
-//   // Verifies that the value of some_expression is even.
-//   EXPECT_THAT(some_expression, IsEven());
-//
-// If the above assertion fails, it will print something like:
-//
-//   Value of: some_expression
-//   Expected: is even
-//     Actual: 7
-//
-// where the description "is even" is automatically calculated from the
-// matcher name IsEven.
-//
-// Argument Type
-// =============
-//
-// Note that the type of the value being matched (arg_type) is
-// determined by the context in which you use the matcher and is
-// supplied to you by the compiler, so you don't need to worry about
-// declaring it (nor can you).  This allows the matcher to be
-// polymorphic.  For example, IsEven() can be used to match any type
-// where the value of "(arg % 2) == 0" can be implicitly converted to
-// a bool.  In the "Bar(IsEven())" example above, if method Bar()
-// takes an int, 'arg_type' will be int; if it takes an unsigned long,
-// 'arg_type' will be unsigned long; and so on.
-//
-// Parameterizing Matchers
-// =======================
-//
-// Sometimes you'll want to parameterize the matcher.  For that you
-// can use another macro:
-//
-//   MATCHER_P(name, param_name, description_string) { statements; }
-//
-// For example:
-//
-//   MATCHER_P(HasAbsoluteValue, value, "") { return abs(arg) == value; }
-//
-// will allow you to write:
-//
-//   EXPECT_THAT(Blah("a"), HasAbsoluteValue(n));
-//
-// which may lead to this message (assuming n is 10):
-//
-//   Value of: Blah("a")
-//   Expected: has absolute value 10
-//     Actual: -9
-//
-// Note that both the matcher description and its parameter are
-// printed, making the message human-friendly.
-//
-// In the matcher definition body, you can write 'foo_type' to
-// reference the type of a parameter named 'foo'.  For example, in the
-// body of MATCHER_P(HasAbsoluteValue, value) above, you can write
-// 'value_type' to refer to the type of 'value'.
-//
-// We also provide MATCHER_P2, MATCHER_P3, ..., up to MATCHER_P$n to
-// support multi-parameter matchers.
-//
-// Describing Parameterized Matchers
-// =================================
-//
-// The last argument to MATCHER*() is a string-typed expression.  The
-// expression can reference all of the matcher's parameters and a
-// special bool-typed variable named 'negation'.  When 'negation' is
-// false, the expression should evaluate to the matcher's description;
-// otherwise it should evaluate to the description of the negation of
-// the matcher.  For example,
-//
-//   using testing::PrintToString;
-//
-//   MATCHER_P2(InClosedRange, low, hi,
-//       std::string(negation ? "is not" : "is") + " in range [" +
-//       PrintToString(low) + ", " + PrintToString(hi) + "]") {
-//     return low <= arg && arg <= hi;
-//   }
-//   ...
-//   EXPECT_THAT(3, InClosedRange(4, 6));
-//   EXPECT_THAT(3, Not(InClosedRange(2, 4)));
-//
-// would generate two failures that contain the text:
-//
-//   Expected: is in range [4, 6]
-//   ...
-//   Expected: is not in range [2, 4]
-//
-// If you specify "" as the description, the failure message will
-// contain the sequence of words in the matcher name followed by the
-// parameter values printed as a tuple.  For example,
-//
-//   MATCHER_P2(InClosedRange, low, hi, "") { ... }
-//   ...
-//   EXPECT_THAT(3, InClosedRange(4, 6));
-//   EXPECT_THAT(3, Not(InClosedRange(2, 4)));
-//
-// would generate two failures that contain the text:
-//
-//   Expected: in closed range (4, 6)
-//   ...
-//   Expected: not (in closed range (2, 4))
-//
-// Types of Matcher Parameters
-// ===========================
-//
-// For the purpose of typing, you can view
-//
-//   MATCHER_Pk(Foo, p1, ..., pk, description_string) { ... }
-//
-// as shorthand for
-//
-//   template <typename p1_type, ..., typename pk_type>
-//   FooMatcherPk<p1_type, ..., pk_type>
-//   Foo(p1_type p1, ..., pk_type pk) { ... }
-//
-// When you write Foo(v1, ..., vk), the compiler infers the types of
-// the parameters v1, ..., and vk for you.  If you are not happy with
-// the result of the type inference, you can specify the types by
-// explicitly instantiating the template, as in Foo<long, bool>(5,
-// false).  As said earlier, you don't get to (or need to) specify
-// 'arg_type' as that's determined by the context in which the matcher
-// is used.  You can assign the result of expression Foo(p1, ..., pk)
-// to a variable of type FooMatcherPk<p1_type, ..., pk_type>.  This
-// can be useful when composing matchers.
-//
-// While you can instantiate a matcher template with reference types,
-// passing the parameters by pointer usually makes your code more
-// readable.  If, however, you still want to pass a parameter by
-// reference, be aware that in the failure message generated by the
-// matcher you will see the value of the referenced object but not its
-// address.
-//
-// Explaining Match Results
-// ========================
-//
-// Sometimes the matcher description alone isn't enough to explain why
-// the match has failed or succeeded.  For example, when expecting a
-// long string, it can be very helpful to also print the diff between
-// the expected string and the actual one.  To achieve that, you can
-// optionally stream additional information to a special variable
-// named result_listener, whose type is a pointer to class
-// MatchResultListener:
-//
-//   MATCHER_P(EqualsLongString, str, "") {
-//     if (arg == str) return true;
-//
-//     *result_listener << "the difference: "
-///                     << DiffStrings(str, arg);
-//     return false;
-//   }
-//
-// Overloading Matchers
-// ====================
-//
-// You can overload matchers with different numbers of parameters:
-//
-//   MATCHER_P(Blah, a, description_string1) { ... }
-//   MATCHER_P2(Blah, a, b, description_string2) { ... }
-//
-// Caveats
-// =======
-//
-// When defining a new matcher, you should also consider implementing
-// MatcherInterface or using MakePolymorphicMatcher().  These
-// approaches require more work than the MATCHER* macros, but also
-// give you more control on the types of the value being matched and
-// the matcher parameters, which may leads to better compiler error
-// messages when the matcher is used wrong.  They also allow
-// overloading matchers based on parameter types (as opposed to just
-// based on the number of parameters).
-//
-// MATCHER*() can only be used in a namespace scope as templates cannot be
-// declared inside of a local class.
-//
-// More Information
-// ================
-//
-// To learn more about using these macros, please search for 'MATCHER'
-// on
-// https://github.com/google/googletest/blob/master/docs/gmock_cook_book.md
-//
-// This file also implements some commonly used argument matchers.  More
-// matchers can be defined by the user implementing the
-// MatcherInterface<T> interface if necessary.
-//
-// See googletest/include/gtest/gtest-matchers.h for the definition of class
-// Matcher, class MatcherInterface, and others.

-
-// Sometimes you want to give an action explicit template parameters
-// that cannot be inferred from its value parameters.  ACTION() and
-// ACTION_P*() don't support that.  ACTION_TEMPLATE() remedies that
-// and can be viewed as an extension to ACTION() and ACTION_P*().
-//
-// The syntax:
-//
-//   ACTION_TEMPLATE(ActionName,
-//                   HAS_m_TEMPLATE_PARAMS(kind1, name1, ..., kind_m, name_m),
-//                   AND_n_VALUE_PARAMS(p1, ..., p_n)) { statements; }
-//
-// defines an action template that takes m explicit template
-// parameters and n value parameters.  name_i is the name of the i-th
-// template parameter, and kind_i specifies whether it's a typename,
-// an integral constant, or a template.  p_i is the name of the i-th
-// value parameter.
-//
-// Example:
-//
-//   // DuplicateArg<k, T>(output) converts the k-th argument of the mock
-//   // function to type T and copies it to *output.
-//   ACTION_TEMPLATE(DuplicateArg,
-//                   HAS_2_TEMPLATE_PARAMS(int, k, typename, T),
-//                   AND_1_VALUE_PARAMS(output)) {
-//     *output = T(::std::get<k>(args));
-//   }
-//   ...
-//     int n;
-//     EXPECT_CALL(mock, Foo(_, _))
-//         .WillOnce(DuplicateArg<1, unsigned char>(&n));
-//
-// To create an instance of an action template, write:
-//
-//   ActionName<t1, ..., t_m>(v1, ..., v_n)
-//
-// where the ts are the template arguments and the vs are the value
-// arguments.  The value argument types are inferred by the compiler.
-// If you want to explicitly specify the value argument types, you can
-// provide additional template arguments:
-//
-//   ActionName<t1, ..., t_m, u1, ..., u_k>(v1, ..., v_n)
-//
-// where u_i is the desired type of v_i.
-//
-// ACTION_TEMPLATE and ACTION/ACTION_P* can be overloaded on the
-// number of value parameters, but not on the number of template
-// parameters.  Without the restriction, the meaning of the following
-// is unclear:
-//
-//   OverloadedAction<int, bool>(x);
-//
-// Are we using a single-template-parameter action where 'bool' refers
-// to the type of x, or are we using a two-template-parameter action
-// where the compiler is asked to infer the type of x?
-//
-// Implementation notes:
-//
-// GMOCK_INTERNAL_*_HAS_m_TEMPLATE_PARAMS and
-// GMOCK_INTERNAL_*_AND_n_VALUE_PARAMS are internal macros for
-// implementing ACTION_TEMPLATE.  The main trick we use is to create
-// new macro invocations when expanding a macro.  For example, we have
-//
-//   #define ACTION_TEMPLATE(name, template_params, value_params)
-//       ... GMOCK_INTERNAL_DECL_##template_params ...
-//
-// which causes ACTION_TEMPLATE(..., HAS_1_TEMPLATE_PARAMS(typename, T), ...)
-// to expand to
-//
-//       ... GMOCK_INTERNAL_DECL_HAS_1_TEMPLATE_PARAMS(typename, T) ...
-//
-// Since GMOCK_INTERNAL_DECL_HAS_1_TEMPLATE_PARAMS is a macro, the
-// preprocessor will continue to expand it to
-//
-//       ... typename T ...
-//
-// This technique conforms to the C++ standard and is portable.  It
-// allows us to implement action templates using O(N) code, where N is
-// the maximum number of template/value parameters supported.  Without
-// using it, we'd have to devote O(N^2) amount of code to implement all
-// combinations of m and n.
-
-// Declares the template parameters.

-//
-// Notes:
-//
-//   1. The arguments are passed by value by default.  If you need to
-//   pass an argument by reference, wrap it inside std::ref().  For
-//   example,
-//
-//     InvokeArgument<1>(5, string("Hello"), std::ref(foo))
-//
-//   passes 5 and string("Hello") by value, and passes foo by
-//   reference.
-//
-//   2. If the callable takes an argument by reference but std::ref() is
-//   not used, it will receive the reference to a copy of the value,
-//   instead of the original value.  For example, when the 0-th
-//   argument of the mock function takes a const string&, the action
-//
-//     InvokeArgument<0>(string("Hello"))
-//
-//   makes a copy of the temporary string("Hello") object and passes a
-//   reference of the copy, instead of the original temporary object,
-//   to the callable.  This makes it easy for a user to define an
-//   InvokeArgument action from temporary values and have it performed
-//   later.

-// Implements class templates NiceMock, NaggyMock, and StrictMock.
-//
-// Given a mock class MockFoo that is created using Google Mock,
-// NiceMock<MockFoo> is a subclass of MockFoo that allows
-// uninteresting calls (i.e. calls to mock methods that have no
-// EXPECT_CALL specs), NaggyMock<MockFoo> is a subclass of MockFoo
-// that prints a warning when an uninteresting call occurs, and
-// StrictMock<MockFoo> is a subclass of MockFoo that treats all
-// uninteresting calls as errors.
-//
-// Currently a mock is naggy by default, so MockFoo and
-// NaggyMock<MockFoo> behave like the same.  However, we will soon
-// switch the default behavior of mocks to be nice, as that in general
-// leads to more maintainable tests.  When that happens, MockFoo will
-// stop behaving like NaggyMock<MockFoo> and start behaving like
-// NiceMock<MockFoo>.
-//
-// NiceMock, NaggyMock, and StrictMock "inherit" the constructors of
-// their respective base class.  Therefore you can write
-// NiceMock<MockFoo>(5, "a") to construct a nice mock where MockFoo
-// has a constructor that accepts (int, const char*), for example.
-//
-// A known limitation is that NiceMock<MockFoo>, NaggyMock<MockFoo>,
-// and StrictMock<MockFoo> only works for mock methods defined using
-// the MOCK_METHOD* family of macros DIRECTLY in the MockFoo class.
-// If a mock method is defined in a base class of MockFoo, the "nice"
-// or "strict" modifier may not affect it, depending on the compiler.
-// In particular, nesting NiceMock, NaggyMock, and StrictMock is NOT
-// supported.

-// A MockFunction<F> type has one mock method whose type is
-// internal::SignatureOfT<F>.  It is useful when you just want your
-// test code to emit some messages and have Google Mock verify the
-// right messages are sent (and perhaps at the right times).  For
-// example, if you are exercising code:
-//
-//   Foo(1);
-//   Foo(2);
-//   Foo(3);
-//
-// and want to verify that Foo(1) and Foo(3) both invoke
-// mock.Bar("a"), but Foo(2) doesn't invoke anything, you can write:
-//
-// TEST(FooTest, InvokesBarCorrectly) {
-//   MyMock mock;
-//   MockFunction<void(string check_point_name)> check;
-//   {
-//     InSequence s;
-//
-//     EXPECT_CALL(mock, Bar("a"));
-//     EXPECT_CALL(check, Call("1"));
-//     EXPECT_CALL(check, Call("2"));
-//     EXPECT_CALL(mock, Bar("a"));
-//   }
-//   Foo(1);
-//   check.Call("1");
-//   Foo(2);
-//   check.Call("2");
-//   Foo(3);
-// }
-//
-// The expectation spec says that the first Bar("a") must happen
-// before check point "1", the second Bar("a") must happen after check
-// point "2", and nothing should happen between the two check
-// points. The explicit check points make it easy to tell which
-// Bar("a") is called by which call to Foo().
-//
-// MockFunction<F> can also be used to exercise code that accepts
-// std::function<internal::SignatureOfT<F>> callbacks. To do so, use
-// AsStdFunction() method to create std::function proxy forwarding to
-// original object's Call. Example:
-//
-// TEST(FooTest, RunsCallbackWithBarArgument) {
-//   MockFunction<int(string)> callback;
-//   EXPECT_CALL(callback, Call("bar")).WillOnce(Return(1));
-//   Foo(callback.AsStdFunction());
-// }
-//
-// The internal::SignatureOfT<F> indirection allows to use other types
-// than just function signature type. This is typically useful when
-// providing a mock for a predefined std::function type. Example:
-//
-// using FilterPredicate = std::function<bool(string)>;
-// void MyFilterAlgorithm(FilterPredicate predicate);
-//
-// TEST(FooTest, FilterPredicateAlwaysAccepts) {
-//   MockFunction<FilterPredicate> predicateMock;
-//   EXPECT_CALL(predicateMock, Call(_)).WillRepeatedly(Return(true));
-//   MyFilterAlgorithm(predicateMock.AsStdFunction());
-// }

-// required to avoid compile errors when the name of the method used in call is
-// a result of macro expansion. See CompilesWithMethodNameExpandedFromMacro
-// tests in internal/gmock-spec-builders_test.cc for more details.
-//
-// This macro supports statements both with and without parameter matchers. If
-// the parameter list is omitted, gMock will accept any parameters, which allows
-// tests to be written that don't need to encode the number of method
-// parameter. This technique may only be used for non-overloaded methods.
-//
-//   // These are the same:
-//   ON_CALL(mock, NoArgsMethod()).WillByDefault(...);
-//   ON_CALL(mock, NoArgsMethod).WillByDefault(...);
-//
-//   // As are these:
-//   ON_CALL(mock, TwoArgsMethod(_, _)).WillByDefault(...);
-//   ON_CALL(mock, TwoArgsMethod).WillByDefault(...);
-//
-//   // Can also specify args if you want, of course:
-//   ON_CALL(mock, TwoArgsMethod(_, 45)).WillByDefault(...);
-//
-//   // Overloads work as long as you specify parameters:
-//   ON_CALL(mock, OverloadedMethod(_)).WillByDefault(...);
-//   ON_CALL(mock, OverloadedMethod(_, _)).WillByDefault(...);
-//
-//   // Oops! Which overload did you want?
-//   ON_CALL(mock, OverloadedMethod).WillByDefault(...);
-//     => ERROR: call to member function 'gmock_OverloadedMethod' is ambiguous
-//
-// How this works: The mock class uses two overloads of the gmock_Method
-// expectation setter method plus an operator() overload on the MockSpec object.
-// In the matcher list form, the macro expands to:
-//
-//   // This statement:
-//   ON_CALL(mock, TwoArgsMethod(_, 45))...
-//
-//   // ...expands to:
-//   mock.gmock_TwoArgsMethod(_, 45)(WithoutMatchers(), nullptr)...
-//   |-------------v---------------||------------v-------------|
-//       invokes first overload        swallowed by operator()
-//
-//   // ...which is essentially:
-//   mock.gmock_TwoArgsMethod(_, 45)...
-//
-// Whereas the form without a matcher list:
-//
-//   // This statement:
-//   ON_CALL(mock, TwoArgsMethod)...
-//
-//   // ...expands to:
-//   mock.gmock_TwoArgsMethod(WithoutMatchers(), nullptr)...
-//   |-----------------------v--------------------------|
-//                 invokes second overload
-//
-//   // ...which is essentially:
-//   mock.gmock_TwoArgsMethod(_, _)...
-//
-// The WithoutMatchers() argument is used to disambiguate overloads and to
-// block the caller from accidentally invoking the second overload directly. The
-// second argument is an internal type derived from the method signature. The
-// failure to disambiguate two overloads of this method in the ON_CALL statement
-// is how we block callers from setting expectations on overloaded methods.

-// FindMaxBipartiteMatching and its helper class.
-//
-// Uses the well-known Ford-Fulkerson max flow method to find a maximum
-// bipartite matching. Flow is considered to be from left to right.
-// There is an implicit source node that is connected to all of the left
-// nodes, and an implicit sink node that is connected to all of the
-// right nodes. All edges have unit capacity.
-//
-// Neither the flow graph nor the residual flow graph are represented
-// explicitly. Instead, they are implied by the information in 'graph' and
-// a vector<int> called 'left_' whose elements are initialized to the
-// value kUnused. This represents the initial state of the algorithm,
-// where the flow graph is empty, and the residual flow graph has the
-// following edges:
-//   - An edge from source to each left_ node
-//   - An edge from each right_ node to sink
-//   - An edge from each left_ node to each right_ node, if the
-//     corresponding edge exists in 'graph'.
-//
-// When the TryAugment() method adds a flow, it sets left_[l] = r for some
-// nodes l and r. This induces the following changes:
-//   - The edges (source, l), (l, r), and (r, sink) are added to the
-//     flow graph.
-//   - The same three edges are removed from the residual flow graph.
-//   - The reverse edges (l, source), (r, l), and (sink, r) are added
-//     to the residual flow graph, which is a directional graph
-//     representing unused flow capacity.
-//
-// When the method augments a flow (moving left_[l] from some r1 to some
-// other r2), this can be thought of as "undoing" the above steps with
-// respect to r1 and "redoing" them with respect to r2.
-//
-// It bears repeating that the flow graph and residual flow graph are
-// never represented explicitly, but can be derived by looking at the
-// information in 'graph' and in left_.
-//

-// Google Mock - a framework for writing C++ mock classes.
-//
-// This file tests that:
-// a. A header file defining a mock class can be included in multiple
-//    translation units without causing a link error.
-// b. Actions and matchers can be instantiated with identical template
-//    arguments in different translation units without causing link
-//    errors.
-//    The following constructs are currently tested:
-//    Actions:
-//      Return()
-//      Return(value)
-//      ReturnNull
-//      ReturnRef
-//      Assign
-//      SetArgPointee
-//      SetArrayArgument
-//      SetErrnoAndReturn
-//      Invoke(function)
-//      Invoke(object, method)
-//      InvokeWithoutArgs(function)
-//      InvokeWithoutArgs(object, method)
-//      InvokeArgument
-//      WithArg
-//      WithArgs
-//      WithoutArgs
-//      DoAll
-//      DoDefault
-//      IgnoreResult
-//      Throw
-//      ACTION()-generated
-//      ACTION_P()-generated
-//      ACTION_P2()-generated
-//    Matchers:
-//      _
-//      A
-//      An
-//      Eq
-//      Gt, Lt, Ge, Le, Ne

-//      AddressSatisfies
-//      AllOf
-//      AnyOf
-//      Not
-//      MatcherCast<T>
-//
-//  Please note: this test does not verify the functioning of these
-//  constructs, only that the programs using them will link successfully.
-//
-// Implementation note:
-// This test requires identical definitions of Interface and Mock to be
-// included in different translation units.  We achieve this by writing
-// them in this header and #including it in gmock_link_test.cc and
-// gmock_link2_test.cc.  Because the symbols generated by the compiler for
-// those constructs must be identical in both translation units,
-// definitions of Interface and Mock tests MUST be kept in the SAME
-// NON-ANONYMOUS namespace in this file.  The test fixture class LinkTest
-// is defined as LinkTest1 in gmock_link_test.cc and as LinkTest2 in
-// gmock_link2_test.cc to avoid producing linker errors.

-ERROR: 3 leaked mock objects found at program exit. Expectations on a mock object are verified when the object is destructed. Leaking a mock means that its expectations aren't verified, which is usually a test bug. If you really intend to leak a mock, you can suppress this error using testing::Mock::AllowLeak(mock_object), or you may use a fake or stub instead of a mock.

-### Generic Build Instructions
-
-#### Setup
-
-To build GoogleTest and your tests that use it, you need to tell your build
-system where to find its headers and source files. The exact way to do it
-depends on which build system you use, and is usually straightforward.
-
-### Build with CMake
-
-GoogleTest comes with a CMake build script
-([CMakeLists.txt](https://github.com/google/googletest/blob/master/CMakeLists.txt))
-that can be used on a wide range of platforms ("C" stands for cross-platform.).
-If you don't have CMake installed already, you can download it for free from
-<http://www.cmake.org/>.
-
-CMake works by generating native makefiles or build projects that can be used in
-the compiler environment of your choice. You can either build GoogleTest as a
-standalone project or it can be incorporated into an existing CMake build for
-another project.
-
-#### Standalone CMake Project
-
-When building GoogleTest as a standalone project, the typical workflow starts
-with
-
-```
-git clone https://github.com/google/googletest.git -b release-1.11.0
-cd googletest        # Main directory of the cloned repository.
-mkdir build          # Create a directory to hold the build output.
-cd build
-cmake ..             # Generate native build scripts for GoogleTest.
-```
-
-The above command also includes GoogleMock by default. And so, if you want to
-build only GoogleTest, you should replace the last command with
-
-```
-cmake .. -DBUILD_GMOCK=OFF
-```
-
-If you are on a \*nix system, you should now see a Makefile in the current
-directory. Just type `make` to build GoogleTest. And then you can simply install
-GoogleTest if you are a system administrator.
-
-```
-make
-sudo make install    # Install in /usr/local/ by default
-```
-
-If you use Windows and have Visual Studio installed, a `gtest.sln` file and
-several `.vcproj` files will be created. You can then build them using Visual
-Studio.
-
-On Mac OS X with Xcode installed, a `.xcodeproj` file will be generated.
-
-#### Incorporating Into An Existing CMake Project
-
-If you want to use GoogleTest in a project which already uses CMake, the easiest
-way is to get installed libraries and headers.
-
-*   Import GoogleTest by using `find_package` (or `pkg_check_modules`). For
-    example, if `find_package(GTest CONFIG REQUIRED)` succeeds, you can use the
-    libraries as `GTest::gtest`, `GTest::gmock`.
-
-And a more robust and flexible approach is to build GoogleTest as part of that
-project directly. This is done by making the GoogleTest source code available to
-the main build and adding it using CMake's `add_subdirectory()` command. This
-has the significant advantage that the same compiler and linker settings are
-used between GoogleTest and the rest of your project, so issues associated with
-using incompatible libraries (eg debug/release), etc. are avoided. This is
-particularly useful on Windows. Making GoogleTest's source code available to the
-main build can be done a few different ways:
-
-*   Download the GoogleTest source code manually and place it at a known
-    location. This is the least flexible approach and can make it more difficult
-    to use with continuous integration systems, etc.
-*   Embed the GoogleTest source code as a direct copy in the main project's
-    source tree. This is often the simplest approach, but is also the hardest to
-    keep up to date. Some organizations may not permit this method.
-*   Add GoogleTest as a git submodule or equivalent. This may not always be
-    possible or appropriate. Git submodules, for example, have their own set of
-    advantages and drawbacks.
-*   Use CMake to download GoogleTest as part of the build's configure step. This
-    approach doesn't have the limitations of the other methods.
-
-The last of the above methods is implemented with a small piece of CMake code
-that downloads and pulls the GoogleTest code into the main build.
-
-Just add to your `CMakeLists.txt`:
-
-```cmake
-include(FetchContent)
-FetchContent_Declare(
-  googletest
-  # Specify the commit you depend on and update it regularly.
-  URL https://github.com/google/googletest/archive/e2239ee6043f73722e7aa812a459f54a28552929.zip
-)
-# For Windows: Prevent overriding the parent project's compiler/linker settings
-set(gtest_force_shared_crt ON CACHE BOOL "" FORCE)
-FetchContent_MakeAvailable(googletest)
-
-# Now simply link against gtest or gtest_main as needed. Eg
-add_executable(example example.cpp)
-target_link_libraries(example gtest_main)
-add_test(NAME example_test COMMAND example)
-```
-
-Note that this approach requires CMake 3.14 or later due to its use of the
-`FetchContent_MakeAvailable()` command.
-
-##### Visual Studio Dynamic vs Static Runtimes
-
-By default, new Visual Studio projects link the C runtimes dynamically but
-GoogleTest links them statically. This will generate an error that looks
-something like the following: gtest.lib(gtest-all.obj) : error LNK2038: mismatch
-detected for 'RuntimeLibrary': value 'MTd_StaticDebug' doesn't match value
-'MDd_DynamicDebug' in main.obj
-
-GoogleTest already has a CMake option for this: `gtest_force_shared_crt`
-
-Enabling this option will make gtest link the runtimes dynamically too, and
-match the project in which it is included.
-
-#### C++ Standard Version
-
-An environment that supports C++11 is required in order to successfully build
-GoogleTest. One way to ensure this is to specify the standard in the top-level
-project, for example by using the `set(CMAKE_CXX_STANDARD 11)` command. If this
-is not feasible, for example in a C project using GoogleTest for validation,
-then it can be specified by adding it to the options for cmake via the
-`DCMAKE_CXX_FLAGS` option.
-
-### Tweaking GoogleTest
-
-GoogleTest can be used in diverse environments. The default configuration may
-not work (or may not work well) out of the box in some environments. However,
-you can easily tweak GoogleTest by defining control macros on the compiler
-command line. Generally, these macros are named like `GTEST_XYZ` and you define
-them to either 1 or 0 to enable or disable a certain feature.
-
-We list the most frequently used macros below. For a complete list, see file
-[include/gtest/internal/gtest-port.h](https://github.com/google/googletest/blob/master/googletest/include/gtest/internal/gtest-port.h).
-
-### Multi-threaded Tests
-
-GoogleTest is thread-safe where the pthread library is available. After
-`#include "gtest/gtest.h"`, you can check the
-`GTEST_IS_THREADSAFE` macro to see whether this is the case (yes if the macro is
-`#defined` to 1, no if it's undefined.).
-
-If GoogleTest doesn't correctly detect whether pthread is available in your
-environment, you can force it with
-
-    -DGTEST_HAS_PTHREAD=1
-
-or
-
-    -DGTEST_HAS_PTHREAD=0
-
-When GoogleTest uses pthread, you may need to add flags to your compiler and/or
-linker to select the pthread library, or you'll get link errors. If you use the
-CMake script, this is taken care of for you. If you use your own build script,
-you'll need to read your compiler and linker's manual to figure out what flags
-to add.
-
-### As a Shared Library (DLL)
-
-GoogleTest is compact, so most users can build and link it as a static library
-for the simplicity. You can choose to use GoogleTest as a shared library (known
-as a DLL on Windows) if you prefer.
-
-To compile *gtest* as a shared library, add
-
-    -DGTEST_CREATE_SHARED_LIBRARY=1
-
-to the compiler flags. You'll also need to tell the linker to produce a shared
-library instead - consult your linker's manual for how to do it.
-
-To compile your *tests* that use the gtest shared library, add
-
-    -DGTEST_LINKED_AS_SHARED_LIBRARY=1
-
-to the compiler flags.
-
-Note: while the above steps aren't technically necessary today when using some
-compilers (e.g. GCC), they may become necessary in the future, if we decide to
-improve the speed of loading the library (see
-<http://gcc.gnu.org/wiki/Visibility> for details). Therefore you are recommended
-to always add the above flags when using GoogleTest as a shared library.
-Otherwise a future release of GoogleTest may break your build script.
-
-### Avoiding Macro Name Clashes
-
-In C++, macros don't obey namespaces. Therefore two libraries that both define a
-macro of the same name will clash if you `#include` both definitions. In case a
-GoogleTest macro clashes with another library, you can force GoogleTest to
-rename its macro to avoid the conflict.
-
-Specifically, if both GoogleTest and some other code define macro FOO, you can
-add
-
-    -DGTEST_DONT_DEFINE_FOO=1
-
-to the compiler flags to tell GoogleTest to change the macro's name from `FOO`
-to `GTEST_FOO`. Currently `FOO` can be `ASSERT_EQ`, `ASSERT_FALSE`, `ASSERT_GE`,
-`ASSERT_GT`, `ASSERT_LE`, `ASSERT_LT`, `ASSERT_NE`, `ASSERT_TRUE`,
-`EXPECT_FALSE`, `EXPECT_TRUE`, `FAIL`, `SUCCEED`, `TEST`, or `TEST_F`. For
-example, with `-DGTEST_DONT_DEFINE_TEST=1`, you'll need to write
-
-    GTEST_TEST(SomeTest, DoesThis) { ... }
-
-instead of
-
-    TEST(SomeTest, DoesThis) { ... }
-
-in order to define a test.

-
-// A class for indicating whether an assertion was successful.  When
-// the assertion wasn't successful, the AssertionResult object
-// remembers a non-empty message that describes how it failed.
-//
-// To create an instance of this class, use one of the factory functions
-// (AssertionSuccess() and AssertionFailure()).
-//
-// This class is useful for two purposes:
-//   1. Defining predicate functions to be used with Boolean test assertions
-//      EXPECT_TRUE/EXPECT_FALSE and their ASSERT_ counterparts
-//   2. Defining predicate-format functions to be
-//      used with predicate assertions (ASSERT_PRED_FORMAT*, etc).
-//
-// For example, if you define IsEven predicate:
-//
-//   testing::AssertionResult IsEven(int n) {
-//     if ((n % 2) == 0)
-//       return testing::AssertionSuccess();
-//     else
-//       return testing::AssertionFailure() << n << " is odd";
-//   }
-//
-// Then the failed expectation EXPECT_TRUE(IsEven(Fib(5)))
-// will print the message
-//
-//   Value of: IsEven(Fib(5))
-//     Actual: false (5 is odd)
-//   Expected: true
-//
-// instead of a more opaque
-//
-//   Value of: IsEven(Fib(5))
-//     Actual: false
-//   Expected: true
-//
-// in case IsEven is a simple Boolean predicate.
-//
-// If you expect your predicate to be reused and want to support informative
-// messages in EXPECT_FALSE and ASSERT_FALSE (negative assertions show up
-// about half as often as positive ones in our tests), supply messages for
-// both success and failure cases:
-//
-//   testing::AssertionResult IsEven(int n) {
-//     if ((n % 2) == 0)
-//       return testing::AssertionSuccess() << n << " is even";
-//     else
-//       return testing::AssertionFailure() << n << " is odd";
-//   }
-//
-// Then a statement EXPECT_FALSE(IsEven(Fib(6))) will print
-//
-//   Value of: IsEven(Fib(6))
-//     Actual: true (8 is even)
-//   Expected: false
-//
-// NB: Predicates that support negative Boolean assertions have reduced
-// performance in positive ones so be careful not to use them in tests
-// that have lots (tens of thousands) of positive Boolean assertions.
-//
-// To use this class with EXPECT_PRED_FORMAT assertions such as:
-//
-//   // Verifies that Foo() returns an even number.
-//   EXPECT_PRED_FORMAT1(IsEven, Foo());
-//
-// you need to define:
-//
-//   testing::AssertionResult IsEven(const char* expr, int n) {
-//     if ((n % 2) == 0)
-//       return testing::AssertionSuccess();
-//     else
-//       return testing::AssertionFailure()
-//         << "Expected: " << expr << " is even\n  Actual: it's " << n;
-//   }
-//
-// If Foo() returns 5, you will see the following message:
-//
-//   Expected: Foo() is even
-//     Actual: it's 5

-// The following macros are useful for writing death tests.
-
-// Here's what happens when an ASSERT_DEATH* or EXPECT_DEATH* is
-// executed:
-//
-//   1. It generates a warning if there is more than one active
-//   thread.  This is because it's safe to fork() or clone() only
-//   when there is a single thread.
-//
-//   2. The parent process clone()s a sub-process and runs the death
-//   test in it; the sub-process exits with code 0 at the end of the
-//   death test, if it hasn't exited already.
-//
-//   3. The parent process waits for the sub-process to terminate.
-//
-//   4. The parent process checks the exit code and error message of
-//   the sub-process.
-//
-// Examples:
-//
-//   ASSERT_DEATH(server.SendMessage(56, "Hello"), "Invalid port number");
-//   for (int i = 0; i < 5; i++) {
-//     EXPECT_DEATH(server.ProcessRequest(i),
-//                  "Invalid request .* in ProcessRequest()")
-//                  << "Failed to die on request " << i;
-//   }
-//
-//   ASSERT_EXIT(server.ExitNow(), ::testing::ExitedWithCode(0), "Exiting");
-//
-//   bool KilledBySIGHUP(int exit_code) {
-//     return WIFSIGNALED(exit_code) && WTERMSIG(exit_code) == SIGHUP;
-//   }
-//
-//   ASSERT_EXIT(client.HangUpServer(), KilledBySIGHUP, "Hanging up!");
-//
-// The final parameter to each of these macros is a matcher applied to any data
-// the sub-process wrote to stderr.  For compatibility with existing tests, a
-// bare string is interpreted as a regular expression matcher.
-//
-// On the regular expressions used in death tests:
-//
-//   On POSIX-compliant systems (*nix), we use the <regex.h> library,
-//   which uses the POSIX extended regex syntax.
-//
-//   On other platforms (e.g. Windows or Mac), we only support a simple regex
-//   syntax implemented as part of Google Test.  This limited
-//   implementation should be enough most of the time when writing
-//   death tests; though it lacks many features you can find in PCRE
-//   or POSIX extended regex syntax.  For example, we don't support
-//   union ("x|y"), grouping ("(xy)"), brackets ("[xy]"), and
-//   repetition count ("x{5,7}"), among others.
-//
-//   Below is the syntax that we do support.  We chose it to be a
-//   subset of both PCRE and POSIX extended regex, so it's easy to
-//   learn wherever you come from.  In the following: 'A' denotes a
-//   literal character, period (.), or a single \\ escape sequence;
-//   'x' and 'y' denote regular expressions; 'm' and 'n' are for
-//   natural numbers.
-//
-//     c     matches any literal character c
-//     \\d   matches any decimal digit
-//     \\D   matches any character that's not a decimal digit
-//     \\f   matches \f
-//     \\n   matches \n
-//     \\r   matches \r
-//     \\s   matches any ASCII whitespace, including \n
-//     \\S   matches any character that's not a whitespace
-//     \\t   matches \t
-//     \\v   matches \v
-//     \\w   matches any letter, _, or decimal digit
-//     \\W   matches any character that \\w doesn't match
-//     \\c   matches any literal character c, which must be a punctuation
-//     .     matches any single character except \n
-//     A?    matches 0 or 1 occurrences of A
-//     A*    matches 0 or many occurrences of A
-//     A+    matches 1 or many occurrences of A
-//     ^     matches the beginning of a string (not that of each line)
-//     $     matches the end of a string (not that of each line)
-//     xy    matches x followed by y
-//
-//   If you accidentally use PCRE or POSIX extended regex features
-//   not implemented by us, you will get a run-time failure.  In that
-//   case, please try to rewrite your regular expression within the
-//   above syntax.
-//
-//   This implementation is *not* meant to be as highly tuned or robust
-//   as a compiled regex library, but should perform well enough for a
-//   death test, which already incurs significant overhead by launching
-//   a child process.
-//
-// Known caveats:
-//
-//   A "threadsafe" style death test obtains the path to the test
-//   program from argv[0] and re-executes it in the sub-process.  For
-//   simplicity, the current implementation doesn't search the PATH
-//   when launching the sub-process.  This means that the user must
-//   invoke the test program via a path that contains at least one
-//   path separator (e.g. path/to/foo_test and
-//   /absolute/path/to/bar_test are fine, but foo_test is not).  This
-//   is rarely a problem as people usually don't put the test binary
-//   directory in PATH.

-// int DieInDebugOr12(int* sideeffect) {

-//
-// EXPECT_DEBUG_DEATH({
-//   // Side-effects here will have an effect after this statement in

-// on systems that support death tests. This allows one to write such a macro on
-// a system that does not support death tests and be sure that it will compile
-// on a death-test supporting system. It is exposed publicly so that systems
-// that have death-tests with stricter requirements than GTEST_HAS_DEATH_TEST
-// can write their own equivalent of EXPECT_DEATH_IF_SUPPORTED and
-// ASSERT_DEATH_IF_SUPPORTED.
-//
-// Parameters:
-//   statement -  A statement that a macro such as EXPECT_DEATH would test
-//                for program termination. This macro has to make sure this
-//                statement is compiled but not executed, to ensure that
-//                EXPECT_DEATH_IF_SUPPORTED compiles with a certain
-//                parameter if and only if EXPECT_DEATH compiles with it.
-//   regex     -  A regex that a macro such as EXPECT_DEATH would use to test
-//                the output of statement.  This parameter has to be
-//                compiled but not evaluated by this macro, to ensure that
-//                this macro only accepts expressions that a macro such as
-//                EXPECT_DEATH would accept.
-//   terminator - Must be an empty statement for EXPECT_DEATH_IF_SUPPORTED
-//                and a return statement for ASSERT_DEATH_IF_SUPPORTED.
-//                This ensures that ASSERT_DEATH_IF_SUPPORTED will not
-//                compile inside functions where ASSERT_DEATH doesn't
-//                compile.
-//
-//  The branch that has an always false condition is used to ensure that
-//  statement and regex are compiled (and thus syntactically correct) but
-//  never executed. The unreachable code macro protects the terminator
-//  statement from generating an 'unreachable code' warning in case
-//  statement unconditionally returns or throws. The Message constructor at
-//  the end allows the syntax of streaming additional messages into the
-//  macro, for compilational compatibility with EXPECT_DEATH/ASSERT_DEATH.

-// Value-parameterized tests allow you to test your code with different
-// parameters without writing multiple copies of the same test.
-//
-// Here is how you use value-parameterized tests:
-
-#if 0
-
-// To write value-parameterized tests, first you should define a fixture
-// class. It is usually derived from testing::TestWithParam<T> (see below for
-// another inheritance scheme that's sometimes useful in more complicated
-// class hierarchies), where the type of your parameter values.
-// TestWithParam<T> is itself derived from testing::Test. T can be any
-// copyable type. If it's a raw pointer, you are responsible for managing the
-// lifespan of the pointed values.
-
-class FooTest : public ::testing::TestWithParam<const char*> {
-  // You can implement all the usual class fixture members here.
-};
-
-// Then, use the TEST_P macro to define as many parameterized tests
-// for this fixture as you want. The _P suffix is for "parameterized"
-// or "pattern", whichever you prefer to think.
-
-TEST_P(FooTest, DoesBlah) {
-  // Inside a test, access the test parameter with the GetParam() method
-  // of the TestWithParam<T> class:
-  EXPECT_TRUE(foo.Blah(GetParam()));
-  ...
-}
-
-TEST_P(FooTest, HasBlahBlah) {
-  ...
-}
-
-// Finally, you can use INSTANTIATE_TEST_SUITE_P to instantiate the test
-// case with any set of parameters you want. Google Test defines a number
-// of functions for generating test parameters. They return what we call
-// (surprise!) parameter generators. Here is a summary of them, which
-// are all in the testing namespace:
-//
-//
-//  Range(begin, end [, step]) - Yields values {begin, begin+step,
-//                               begin+step+step, ...}. The values do not
-//                               include end. step defaults to 1.
-//  Values(v1, v2, ..., vN)    - Yields values {v1, v2, ..., vN}.
-//  ValuesIn(container)        - Yields values from a C-style array, an STL
-//  ValuesIn(begin,end)          container, or an iterator range [begin, end).
-//  Bool()                     - Yields sequence {false, true}.
-//  Combine(g1, g2, ..., gN)   - Yields all combinations (the Cartesian product
-//                               for the math savvy) of the values generated
-//                               by the N generators.
-//
-// For more details, see comments at the definitions of these functions below
-// in this file.
-//
-// The following statement will instantiate tests from the FooTest test suite
-// each with parameter values "meeny", "miny", and "moe".
-
-INSTANTIATE_TEST_SUITE_P(InstantiationName,
-                         FooTest,
-                         Values("meeny", "miny", "moe"));
-
-// To distinguish different instances of the pattern, (yes, you
-// can instantiate it more than once) the first argument to the
-// INSTANTIATE_TEST_SUITE_P macro is a prefix that will be added to the
-// actual test suite name. Remember to pick unique prefixes for different
-// instantiations. The tests from the instantiation above will have
-// these names:
-//
-//    * InstantiationName/FooTest.DoesBlah/0 for "meeny"
-//    * InstantiationName/FooTest.DoesBlah/1 for "miny"
-//    * InstantiationName/FooTest.DoesBlah/2 for "moe"
-//    * InstantiationName/FooTest.HasBlahBlah/0 for "meeny"
-//    * InstantiationName/FooTest.HasBlahBlah/1 for "miny"
-//    * InstantiationName/FooTest.HasBlahBlah/2 for "moe"
-//
-// You can use these names in --gtest_filter.
-//
-// This statement will instantiate all tests from FooTest again, each
-// with parameter values "cat" and "dog":
-
-const char* pets[] = {"cat", "dog"};
-INSTANTIATE_TEST_SUITE_P(AnotherInstantiationName, FooTest, ValuesIn(pets));
-
-// The tests from the instantiation above will have these names:
-//
-//    * AnotherInstantiationName/FooTest.DoesBlah/0 for "cat"
-//    * AnotherInstantiationName/FooTest.DoesBlah/1 for "dog"
-//    * AnotherInstantiationName/FooTest.HasBlahBlah/0 for "cat"
-//    * AnotherInstantiationName/FooTest.HasBlahBlah/1 for "dog"
-//
-// Please note that INSTANTIATE_TEST_SUITE_P will instantiate all tests
-// in the given test suite, whether their definitions come before or
-// AFTER the INSTANTIATE_TEST_SUITE_P statement.
-//
-// Please also note that generator expressions (including parameters to the
-// generators) are evaluated in InitGoogleTest(), after main() has started.
-// This allows the user on one hand, to adjust generator parameters in order
-// to dynamically determine a set of tests to run and on the other hand,
-// give the user a chance to inspect the generated tests with Google Test
-// reflection API before RUN_ALL_TESTS() is executed.
-//
-// You can see samples/sample7_unittest.cc and samples/sample8_unittest.cc
-// for more examples.
-//
-// In the future, we plan to publish the API for defining new parameter
-// generators. But for now this interface remains part of the internal
-// implementation and is subject to change.
-//
-//
-// A parameterized test fixture must be derived from testing::Test and from
-// testing::WithParamInterface<T>, where T is the type of the parameter
-// values. Inheriting from TestWithParam<T> satisfies that requirement because
-// TestWithParam<T> inherits from both Test and WithParamInterface. In more
-// complicated hierarchies, however, it is occasionally useful to inherit
-// separately from Test and WithParamInterface. For example:
-
-class BaseTest : public ::testing::Test {
-  // You can inherit all the usual members for a non-parameterized test
-  // fixture here.
-};
-
-class DerivedTest : public BaseTest, public ::testing::WithParamInterface<int> {
-  // The usual test fixture members go here too.
-};
-
-TEST_F(BaseTest, HasFoo) {
-  // This is an ordinary non-parameterized test.
-}

-// This file implements a universal value printer that can print a
-// value of any type T:
-//
-//   void ::testing::internal::UniversalPrinter<T>::Print(value, ostream_ptr);
-//
-// A user can teach this function how to print a class type T by
-// defining either operator<<() or PrintTo() in the namespace that
-// defines T.  More specifically, the FIRST defined function in the
-// following list will be used (assuming T is defined in namespace
-// foo):
-//
-//   1. foo::PrintTo(const T&, ostream*)
-//   2. operator<<(ostream&, const T&) defined in either foo or the
-//      global namespace.
-//
-// However if T is an STL-style container then it is printed element-wise
-// unless foo::PrintTo(const T&, ostream*) is defined. Note that
-// operator<<() is ignored for container types.
-//
-// If none of the above is defined, it will print the debug string of
-// the value if it is a protocol buffer, or print the raw bytes in the
-// value otherwise.
-//
-// To aid debugging: when T is a reference type, the address of the
-// value is also printed; when T is a (const) char pointer, both the
-// pointer value and the NUL-terminated string it points to are
-// printed.
-//
-// We also provide some convenient wrappers:
-//
-//   // Prints a value to a string.  For a (const or not) char
-//   // pointer, the NUL-terminated string (but not the pointer) is
-//   // printed.
-//   std::string ::testing::PrintToString(const T& value);
-//
-//   // Prints a value tersely: for a reference type, the referenced
-//   // value (but not the address) is printed; for a (const or not) char
-//   // pointer, the NUL-terminated string (but not the pointer) is
-//   // printed.
-//   void ::testing::internal::UniversalTersePrint(const T& value, ostream*);
-//
-//   // Prints value using the type inferred by the compiler.  The difference
-//   // from UniversalTersePrint() is that this function prints both the
-//   // pointer and the NUL-terminated string for a (const or not) char pointer.
-//   void ::testing::internal::UniversalPrint(const T& value, ostream*);
-//
-//   // Prints the fields of a tuple tersely to a string vector, one
-//   // element for each field. Tuple support must be enabled in
-//   // gtest-port.h.
-//   std::vector<string> UniversalTersePrintTupleFieldsToStrings(
-//       const Tuple& value);
-//
-// Known limitation:
-//
-// The print primitives print the elements of an STL-style container
-// using the compiler-inferred type of *iter where iter is a
-// const_iterator of the container.  When const_iterator is an input
-// iterator but not a forward iterator, this inferred type may not
-// match value_type, and the print output may be incorrect.  In
-// practice, this is rarely a problem as for most containers
-// const_iterator is a forward iterator.  We'll fix this if there's an
-// actual need for it.  Note that this fix cannot rely on value_type
-// being defined as many user-defined container types don't have
-// value_type.

-
-// Typed (aka type-driven) tests repeat the same test for types in a
-// list.  You must know which types you want to test with when writing
-// typed tests. Here's how you do it:
-
-#if 0
-
-// First, define a fixture class template.  It should be parameterized
-// by a type.  Remember to derive it from testing::Test.
-template <typename T>
-class FooTest : public testing::Test {
- public:
-  ...
-  typedef std::list<T> List;
-  static T shared_;
-  T value_;
-};
-
-// Next, associate a list of types with the test suite, which will be
-// repeated for each type in the list.  The typedef is necessary for
-// the macro to parse correctly.
-typedef testing::Types<char, int, unsigned int> MyTypes;
-TYPED_TEST_SUITE(FooTest, MyTypes);
-
-// If the type list contains only one type, you can write that type
-// directly without Types<...>:
-//   TYPED_TEST_SUITE(FooTest, int);
-
-// Then, use TYPED_TEST() instead of TEST_F() to define as many typed
-// tests for this test suite as you want.
-TYPED_TEST(FooTest, DoesBlah) {
-  // Inside a test, refer to the special name TypeParam to get the type
-  // parameter.  Since we are inside a derived class template, C++ requires
-  // us to visit the members of FooTest via 'this'.
-  TypeParam n = this->value_;
-
-  // To visit static members of the fixture, add the TestFixture::
-  // prefix.
-  n += TestFixture::shared_;
-
-  // To refer to typedefs in the fixture, add the "typename
-  // TestFixture::" prefix.
-  typename TestFixture::List values;
-  values.push_back(n);
-  ...
-}
-
-TYPED_TEST(FooTest, HasPropertyA) { ... }
-
-// TYPED_TEST_SUITE takes an optional third argument which allows to specify a
-// class that generates custom test name suffixes based on the type. This should
-// be a class which has a static template function GetName(int index) returning
-// a string for each type. The provided integer index equals the index of the
-// type in the provided type list. In many cases the index can be ignored.
-//
-// For example:
-//   class MyTypeNames {
-//    public:
-//     template <typename T>
-//     static std::string GetName(int) {
-//       if (std::is_same<T, char>()) return "char";
-//       if (std::is_same<T, int>()) return "int";
-//       if (std::is_same<T, unsigned int>()) return "unsignedInt";
-//     }
-//   };
-//   TYPED_TEST_SUITE(FooTest, MyTypes, MyTypeNames);
-
-#endif  // 0
-
-// Type-parameterized tests are abstract test patterns parameterized
-// by a type.  Compared with typed tests, type-parameterized tests
-// allow you to define the test pattern without knowing what the type
-// parameters are.  The defined pattern can be instantiated with
-// different types any number of times, in any number of translation
-// units.
-//
-// If you are designing an interface or concept, you can define a
-// suite of type-parameterized tests to verify properties that any
-// valid implementation of the interface/concept should have.  Then,
-// each implementation can easily instantiate the test suite to verify
-// that it conforms to the requirements, without having to write
-// similar tests repeatedly.  Here's an example:
-
-#if 0
-
-// First, define a fixture class template.  It should be parameterized
-// by a type.  Remember to derive it from testing::Test.
-template <typename T>
-class FooTest : public testing::Test {
-  ...
-};
-
-// Next, declare that you will define a type-parameterized test suite
-// (the _P suffix is for "parameterized" or "pattern", whichever you
-// prefer):
-TYPED_TEST_SUITE_P(FooTest);
-
-// Then, use TYPED_TEST_P() to define as many type-parameterized tests
-// for this type-parameterized test suite as you want.
-TYPED_TEST_P(FooTest, DoesBlah) {
-  // Inside a test, refer to TypeParam to get the type parameter.
-  TypeParam n = 0;
-  ...
-}
-
-TYPED_TEST_P(FooTest, HasPropertyA) { ... }
-
-// Now the tricky part: you need to register all test patterns before
-// you can instantiate them.  The first argument of the macro is the
-// test suite name; the rest are the names of the tests in this test
-// case.
-REGISTER_TYPED_TEST_SUITE_P(FooTest,
-                            DoesBlah, HasPropertyA);
-
-// Finally, you are free to instantiate the pattern with the types you
-// want.  If you put the above code in a header file, you can #include
-// it in multiple C++ source files and instantiate it multiple times.
-//
-// To distinguish different instances of the pattern, the first
-// argument to the INSTANTIATE_* macro is a prefix that will be added
-// to the actual test suite name.  Remember to pick unique prefixes for
-// different instances.
-typedef testing::Types<char, int, unsigned int> MyTypes;
-INSTANTIATE_TYPED_TEST_SUITE_P(My, FooTest, MyTypes);
-
-// If the type list contains only one type, you can write that type
-// directly without Types<...>:
-//   INSTANTIATE_TYPED_TEST_SUITE_P(My, FooTest, int);

-//   Usage Guide.  Therefore, you are advised to use the

-//   equal.
-//
-//   2. The {ASSERT|EXPECT}_??() macros do pointer comparisons on
-//   pointers (in particular, C strings).  Therefore, if you use it
-//   with two C strings, you are testing how their locations in memory

-// The `factory` argument is a factory callable (move-constructible) object or

-// tests registered with the same `test_suite_name` must return the same
-// fixture type. This is checked at runtime.

-// the `SetUpTestSuite` and `TearDownTestSuite` for it.
-//
-// Must be called before `RUN_ALL_TESTS()` is invoked, otherwise behavior is
-// undefined.

-# Customization Points
-
-The custom directory is an injection point for custom user configurations.
-
-## Header `gtest.h`
-
-### The following macros can be defined:
-
-*   `GTEST_OS_STACK_TRACE_GETTER_` - The name of an implementation of
-    `OsStackTraceGetterInterface`.
-*   `GTEST_CUSTOM_TEMPDIR_FUNCTION_` - An override for `testing::TempDir()`. See
-    `testing::TempDir` for semantics and signature.
-
-## Header `gtest-port.h`
-
-The following macros can be defined:
-
-### Logging:
-
-*   `GTEST_LOG_(severity)`
-*   `GTEST_CHECK_(condition)`
-*   Functions `LogToStderr()` and `FlushInfoLog()` have to be provided too.
-
-### Threading:
-
-*   `GTEST_HAS_NOTIFICATION_` - Enabled if Notification is already provided.
-*   `GTEST_HAS_MUTEX_AND_THREAD_LOCAL_` - Enabled if `Mutex` and `ThreadLocal`
-    are already provided. Must also provide `GTEST_DECLARE_STATIC_MUTEX_(mutex)`
-    and `GTEST_DEFINE_STATIC_MUTEX_(mutex)`
-*   `GTEST_EXCLUSIVE_LOCK_REQUIRED_(locks)`
-*   `GTEST_LOCK_EXCLUDED_(locks)`

-// Environment-describing macros
-// -----------------------------
-//
-// Google Test can be used in many different environments.  Macros in
-// this section tell Google Test what kind of environment it is being
-// used in, such that Google Test can provide environment-specific
-// features and implementations.
-//
-// Google Test tries to automatically detect the properties of its
-// environment, so users usually don't need to worry about these
-// macros.  However, the automatic detection is not perfect.
-// Sometimes it's necessary for a user to define some of the following
-// macros in the build script to override Google Test's decisions.
-//
-// If the user doesn't define a macro in the list, Google Test will
-// provide a default definition.  After this header is #included, all
-// macros in this list will be defined to either 1 or 0.
-//
-// Notes to maintainers:
-//   - Each macro here is a user-tweakable knob; do not grow the list
-//     lightly.
-//   - Use #if to key off these macros.  Don't use #ifdef or "#if
-//     defined(...)", which will not work as these macros are ALWAYS
-//     defined.
-//
-//   GTEST_HAS_CLONE          - Define it to 1/0 to indicate that clone(2)
-//                              is/isn't available.
-//   GTEST_HAS_EXCEPTIONS     - Define it to 1/0 to indicate that exceptions
-//                              are enabled.
-//   GTEST_HAS_POSIX_RE       - Define it to 1/0 to indicate that POSIX regular
-//                              expressions are/aren't available.
-//   GTEST_HAS_PTHREAD        - Define it to 1/0 to indicate that <pthread.h>
-//                              is/isn't available.
-//   GTEST_HAS_RTTI           - Define it to 1/0 to indicate that RTTI is/isn't

-//   GTEST_HAS_STREAM_REDIRECTION
-//                            - Define it to 1/0 to indicate whether the

-// Platform-indicating macros
-// --------------------------
-//
-// Macros indicating the platform on which Google Test is being used
-// (a macro is defined to 1 if compiled on the given platform;
-// otherwise UNDEFINED -- it's never defined to 0.).  Google Test
-// defines these macros automatically.  Code outside Google Test MUST
-// NOT define them.
-//
-//   GTEST_OS_AIX      - IBM AIX
-//   GTEST_OS_CYGWIN   - Cygwin
-//   GTEST_OS_DRAGONFLY - DragonFlyBSD
-//   GTEST_OS_FREEBSD  - FreeBSD
-//   GTEST_OS_FUCHSIA  - Fuchsia
-//   GTEST_OS_GNU_HURD - GNU/Hurd
-//   GTEST_OS_GNU_KFREEBSD - GNU/kFreeBSD
-//   GTEST_OS_HAIKU    - Haiku
-//   GTEST_OS_HPUX     - HP-UX
-//   GTEST_OS_LINUX    - Linux
-//     GTEST_OS_LINUX_ANDROID - Google Android
-//   GTEST_OS_MAC      - Mac OS X
-//     GTEST_OS_IOS    - iOS
-//   GTEST_OS_NACL     - Google Native Client (NaCl)
-//   GTEST_OS_NETBSD   - NetBSD
-//   GTEST_OS_OPENBSD  - OpenBSD
-//   GTEST_OS_OS2      - OS/2
-//   GTEST_OS_QNX      - QNX
-//   GTEST_OS_SOLARIS  - Sun Solaris
-//   GTEST_OS_WINDOWS  - Windows (Desktop, MinGW, or Mobile)
-//     GTEST_OS_WINDOWS_DESKTOP  - Windows Desktop
-//     GTEST_OS_WINDOWS_MINGW    - MinGW
-//     GTEST_OS_WINDOWS_MOBILE   - Windows Mobile
-//     GTEST_OS_WINDOWS_PHONE    - Windows Phone
-//     GTEST_OS_WINDOWS_RT       - Windows Store App/WinRT
-//   GTEST_OS_ZOS      - z/OS
-//
-// Among the platforms, Cygwin, Linux, Mac OS X, and Windows have the
-// most stable support.  Since core members of the Google Test project
-// don't have access to other platforms, support for them may be less
-// stable.  If you notice any problems on your platform, please notify
-// googletestframework@googlegroups.com (patches for fixing them are
-// even more welcome!).
-//
-// It is possible that none of the GTEST_OS_* macros are defined.
-
-// Feature-indicating macros
-// -------------------------
-//
-// Macros indicating which Google Test features are available (a macro
-// is defined to 1 if the corresponding feature is supported;
-// otherwise UNDEFINED -- it's never defined to 0.).  Google Test
-// defines these macros automatically.  Code outside Google Test MUST
-// NOT define them.
-//
-// These macros are public so that portable tests can be written.
-// Such tests typically surround code using a feature with an #if
-// which controls that code.  For example:
-//
-// #if GTEST_HAS_DEATH_TEST
-//   EXPECT_DEATH(DoSomethingDeadly());
-// #endif
-//
-//   GTEST_HAS_DEATH_TEST   - death tests
-//   GTEST_HAS_TYPED_TEST   - typed tests
-//   GTEST_HAS_TYPED_TEST_P - type-parameterized tests
-//   GTEST_IS_THREADSAFE    - Google Test is thread-safe.
-//   GTEST_USES_RE2         - the RE2 regular expression library is used
-//   GTEST_USES_POSIX_RE    - enhanced POSIX regex is used. Do not confuse with
-//                            GTEST_HAS_POSIX_RE (see above) which users can
-//                            define themselves.
-//   GTEST_USES_SIMPLE_RE   - our own simple regex is used;
-//                            the above RE\b(s) are mutually exclusive.
-
-// Misc public macros
-// ------------------
-//
-//   GTEST_FLAG(flag_name)  - references the variable corresponding to
-//                            the given Google Test flag.
-
-// Internal utilities
-// ------------------
-//
-// The following macros and utilities are for Google Test's INTERNAL
-// use only.  Code outside Google Test MUST NOT USE THEM DIRECTLY.
-//
-// Macros for basic C++ coding:
-//   GTEST_AMBIGUOUS_ELSE_BLOCKER_ - for disabling a gcc warning.
-//   GTEST_ATTRIBUTE_UNUSED_  - declares that a class' instances or a
-//                              variable don't have to be used.
-//   GTEST_MUST_USE_RESULT_   - declares that a function's result must be used.
-//   GTEST_INTENTIONAL_CONST_COND_PUSH_ - start code section where MSVC C4127 is
-//                                        suppressed (constant conditional).
-//   GTEST_INTENTIONAL_CONST_COND_POP_  - finish code section where MSVC C4127
-//                                        is suppressed.
-//   GTEST_INTERNAL_HAS_ANY - for enabling UniversalPrinter<std::any> or
-//                            UniversalPrinter<absl::any> specializations.
-//   GTEST_INTERNAL_HAS_OPTIONAL - for enabling UniversalPrinter<std::optional>
-//   or
-//                                 UniversalPrinter<absl::optional>
-//                                 specializations.
-//   GTEST_INTERNAL_HAS_STRING_VIEW - for enabling Matcher<std::string_view> or
-//                                    Matcher<absl::string_view>
-//                                    specializations.
-//   GTEST_INTERNAL_HAS_VARIANT - for enabling UniversalPrinter<std::variant> or
-//                                UniversalPrinter<absl::variant>
-//                                specializations.
-//
-// Synchronization:
-//   Mutex, MutexLock, ThreadLocal, GetThreadCount()
-//                            - synchronization primitives.
-//
-// Regular expressions:
-//   RE             - a simple regular expression class using
-//                     1) the RE2 syntax on all platforms when built with RE2
-//                        and Abseil as dependencies
-//                     2) the POSIX Extended Regular Expression syntax on
-//                        UNIX-like platforms,
-//                     3) A reduced regular exception syntax on other platforms,
-//                        including Windows.
-// Logging:
-//   GTEST_LOG_()   - logs messages at the specified severity level.
-//   LogToStderr()  - directs all log messages to stderr.
-//   FlushInfoLog() - flushes informational log messages.
-//
-// Stdout and stderr capturing:
-//   CaptureStdout()     - starts capturing stdout.
-//   GetCapturedStdout() - stops capturing stdout and returns the captured
-//                         string.
-//   CaptureStderr()     - starts capturing stderr.
-//   GetCapturedStderr() - stops capturing stderr and returns the captured
-//                         string.
-//
-// Integer types:
-//   TypeWithSize   - maps an integer to a int type.
-//   TimeInMillis   - integers of known sizes.
-//   BiggestInt     - the biggest signed integer type.
-//
-// Command-line utilities:
-//   GetInjectableArgvs() - returns the command line as a vector of strings.
-//
-// Environment variable utilities:
-//   GetEnv()             - gets the value of an environment variable.
-//   BoolFromGTestEnv()   - parses a bool environment variable.
-//   Int32FromGTestEnv()  - parses an int32_t environment variable.
-//   StringFromGTestEnv() - parses a string environment variable.
-//
-// Deprecation warnings:
-//   GTEST_INTERNAL_DEPRECATED(message) - attribute marking a function as
-//                                        deprecated; calling a marked function
-//                                        should generate a compiler warning

-// how do you know the pointer is really of type SubclassOfFoo?  It
-// could be a bare Foo, or of type DifferentSubclassOfFoo.  Thus,
-// when you downcast, you should use this macro.  In debug mode, we

-
-// A sample program demonstrating using Google C++ testing framework.
-
-// This sample shows how to write a simple unit test for a function,
-// using Google C++ testing framework.
-//
-// Writing a unit test using Google C++ testing framework is easy as 1-2-3:
-
-// Step 1. Include necessary header files such that the stuff your
-// test logic needs is declared.
-//
-// Don't forget gtest.h, which declares the testing framework.
-
-#include "sample1.h"
-
-#include <limits.h>
-
-#include "gtest/gtest.h"
-namespace {
-
-// Step 2. Use the TEST macro to define your tests.
-//
-// TEST has two parameters: the test case name and the test name.
-// After using the macro, you should define your test logic between a
-// pair of braces.  You can use a bunch of macros to indicate the
-// success or failure of a test.  EXPECT_TRUE and EXPECT_EQ are
-// examples of such macros.  For a complete list, see gtest.h.
-//
-// <TechnicalDetails>
-//
-// In Google Test, tests are grouped into test cases.  This is how we
-// keep test code organized.  You should put logically related tests
-// into the same test case.
-//
-// The test case name and the test name should both be valid C++
-// identifiers.  And you should not use underscore (_) in the names.
-//
-// Google Test guarantees that each test you define is run exactly
-// once, but it makes no guarantee on the order the tests are
-// executed.  Therefore, you should write your tests in such a way
-// that their results don't depend on their order.
-//
-// </TechnicalDetails>
-
-// Tests Factorial().
-
-// Tests factorial of negative numbers.
-TEST(FactorialTest, Negative) {
-  // This test is named "Negative", and belongs to the "FactorialTest"
-  // test case.
-  EXPECT_EQ(1, Factorial(-5));
-  EXPECT_EQ(1, Factorial(-1));
-  EXPECT_GT(Factorial(-10), 0);
-
-  // <TechnicalDetails>
-  //
-  // EXPECT_EQ(expected, actual) is the same as
-  //
-  //   EXPECT_TRUE((expected) == (actual))
-  //
-  // except that it will print both the expected value and the actual
-  // value when the assertion fails.  This is very helpful for
-  // debugging.  Therefore in this case EXPECT_EQ is preferred.
-  //
-  // On the other hand, EXPECT_TRUE accepts any Boolean expression,
-  // and is thus more general.
-  //
-  // </TechnicalDetails>
-}
-
-// Tests factorial of 0.
-TEST(FactorialTest, Zero) { EXPECT_EQ(1, Factorial(0)); }
-
-// Tests factorial of positive numbers.
-TEST(FactorialTest, Positive) {
-  EXPECT_EQ(1, Factorial(1));
-  EXPECT_EQ(2, Factorial(2));
-  EXPECT_EQ(6, Factorial(3));
-  EXPECT_EQ(40320, Factorial(8));
-}
-
-// Tests IsPrime()
-
-// Tests negative input.
-TEST(IsPrimeTest, Negative) {
-  // This test belongs to the IsPrimeTest test case.
-
-  EXPECT_FALSE(IsPrime(-1));
-  EXPECT_FALSE(IsPrime(-2));
-  EXPECT_FALSE(IsPrime(INT_MIN));
-}
-
-// Tests some trivial cases.
-TEST(IsPrimeTest, Trivial) {
-  EXPECT_FALSE(IsPrime(0));
-  EXPECT_FALSE(IsPrime(1));
-  EXPECT_TRUE(IsPrime(2));
-  EXPECT_TRUE(IsPrime(3));
-}
-
-// Tests positive input.
-TEST(IsPrimeTest, Positive) {
-  EXPECT_FALSE(IsPrime(4));
-  EXPECT_TRUE(IsPrime(5));
-  EXPECT_FALSE(IsPrime(6));
-  EXPECT_TRUE(IsPrime(23));
-}
-}  // namespace
-
-// Step 3. Call RUN_ALL_TESTS() in main().
-//
-// We do this by linking in src/gtest_main.cc file, which consists of
-// a main() function which calls RUN_ALL_TESTS() for us.
-//
-// This runs all the tests you've defined, prints the result, and
-// returns 0 if successful, or 1 otherwise.
-//
-// Did you notice that we didn't register the tests?  The
-// RUN_ALL_TESTS() macro magically knows about all the tests we
-// defined.  Isn't this convenient?

-// A sample program demonstrating using Google C++ testing framework.
-
-// In this example, we use a more advanced feature of Google Test called
-// test fixture.
-//
-// A test fixture is a place to hold objects and functions shared by
-// all tests in a test case.  Using a test fixture avoids duplicating
-// the test code necessary to initialize and cleanup those common
-// objects for each test.  It is also useful for defining sub-routines
-// that your tests need to invoke a lot.
-//
-// <TechnicalDetails>
-//
-// The tests share the test fixture in the sense of code sharing, not
-// data sharing.  Each test is given its own fresh copy of the
-// fixture.  You cannot expect the data modified by one test to be
-// passed on to another test, which is a bad idea.
-//
-// The reason for this design is that tests should be independent and
-// repeatable.  In particular, a test should not fail as the result of
-// another test's failure.  If one test depends on info produced by
-// another test, then the two tests should really be one big test.
-//
-// The macros for indicating the success/failure of a test
-// (EXPECT_TRUE, FAIL, etc) need to know what the current test is
-// (when Google Test prints the test result, it tells you which test
-// each failure belongs to).  Technically, these macros invoke a
-// member function of the Test class.  Therefore, you cannot use them
-// in a global function.  That's why you should put test sub-routines
-// in a test fixture.

-// Sometimes, more than one test cases may want to use the same or

-// system resources like fonts and brushes.  In Google Test, you do

-// test fixture, and then have each test case use a fixture derived

-// A few implementation notes:  Like the Linux version, the Windows
-// implementation uses pipes for child-to-parent communication. But due to
-// the specifics of pipes on Windows, some extra steps are required:
-//
-// 1. The parent creates a communication pipe and stores handles to both
-//    ends of it.
-// 2. The parent starts the child and provides it with the information
-//    necessary to acquire the handle to the write end of the pipe.
-// 3. The child acquires the write end of the pipe and signals the parent
-//    using a Windows event.
-// 4. Now the parent can release the write end of the pipe on its side. If
-//    this is done before step 3, the object's reference count goes down to
-//    0 and it is destroyed, preventing the child from acquiring it. The
-//    parent now has to release it, or read operations on the read end of
-//    the pipe will not return when the child terminates.
-// 5. The parent reads child's output through the pipe (outcome code and
-//    any possible error messages) from the pipe, and its stderr and then
-//    determines whether to fail the test.
-//
-// Note: to distinguish Win32 API calls from the local method and function
-// calls, the former are explicitly resolved in the global namespace.

-"""Unit test for Google Test fail_fast.
-
-A user can specify if a Google Test program should continue test execution
-after a test failure via the GTEST_FAIL_FAST environment variable or the
---gtest_fail_fast flag. The default value of the flag can also be changed
-by Bazel fail fast environment variable TESTBRIDGE_TEST_RUNNER_FAIL_FAST.
-
-This script tests such functionality by invoking googletest-failfast-unittest_
-(a program written with Google Test) with different environments and command
-line flags.

-"""Unit test for Google Test test filters.
-
-A user can specify which test(s) in a Google Test program to run via either
-the GTEST_FILTER environment variable or the --gtest_filter flag.
-This script tests such functionality by invoking
-googletest-filter-unittest_ (a program written with Google Test) with different
-environments and command line flags.
-
-Note that test sharding may also influence which tests are filtered. Therefore,
-we test that here also.
