-// 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.

-// 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_.
-// As an optimization, there is a second vector<int> called right_ which
-// does not provide any new information. Instead, it enables more
-// efficient queries about edges entering or leaving the right-side nodes
-// of the flow or residual flow graphs. The following invariants are

-// 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. The reason is
-// that C++ doesn't yet allow function-local types to be used to
-// instantiate templates. The up-coming C++0x standard will fix this.
-// Once that's done, we'll consider supporting using ACTION*() inside
-// a function.
-// MORE INFORMATION:
-// To learn more about using these macros, please search for 'ACTION'
-// on http://code.google.com/p/googlemock/wiki/CookBook.

-// 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::tr1::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.

-// A MockFunction<F> class has one mock method whose type is F. It is

-// 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"));
-// check.Call("1");
-// check.Call("2");
-// 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().

-// 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, with up-to 10 arguments. Therefore
-// you can write NiceMock<MockFoo>(5, "a") to construct a nice mock
-// where MockFoo has a constructor that accepts (int, const char*),
-// 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.
-// Another known limitation is that the constructors of the base mock
-// cannot have arguments passed by non-const reference, which are
-// banned by the Google C++ style guide anyway.

-// 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.
-// MATCHER(IsEven, "") { return (arg % 2) == 0; }
-// // 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; }
-// MATCHER_P(HasAbsoluteValue, value, "") { return abs(arg) == value; }
-// 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_P10 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,
-// 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, "") { ... }
-// Expected: in closed range (4, 6)
-// Expected: not (in closed range (2, 4))
-// Types of Matcher Parameters
-// ===========================
-// MATCHER_Pk(Foo, p1, ..., pk, description_string) { ... }
-// 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. The reason is
-// Once that's done, we'll consider supporting using MATCHER*() inside
-// More Information

-// 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
-// use dynamic_cast<> to double-check the downcast is legal (we die
-// if it's not). In normal mode, we do the efficient static_cast<>

-// On the regular expressions used in death tests:

-// On other platforms (e.g. Windows), 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.

-// 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.

-// A "smart" pointer type with reference tracking. Every pointer to a
-// particular object is kept on a circular linked list. When the last pointer
-// to an object is destroyed or reassigned, the object is deleted.
-// Used properly, this deletes the object when the last reference goes away.
-// There are several caveats:
-// - Like all reference counting schemes, cycles lead to leaks.
-// - Each smart pointer is actually two pointers (8 bytes instead of 4).
-// - Every time a pointer is assigned, the entire list of pointers to that
-// object is traversed. This class is therefore NOT SUITABLE when there
-// will often be more than two or three pointers to a particular object.
-// - References are only tracked as long as linked_ptr<> objects are copied.
-// If a linked_ptr<> is converted to a raw pointer and back, BAD THINGS
-// will happen (double deletion).
-// A good use of this class is storing object references in STL containers.
-// You can safely put linked_ptr<> in a vector<>.
-// Other uses may not be as good.
-// Note: If you use an incomplete type with linked_ptr<>, the class
-// *containing* linked_ptr<> must have a constructor and destructor (even
-// if they do nothing!).
-// Bill Gibbons suggested we use something like this.
-// Thread Safety:
-// Unlike other linked_ptr implementations, in this implementation
-// a linked_ptr object is thread-safe in the sense that:
-// - it's safe to copy linked_ptr objects concurrently,
-// - it's safe to copy *from* a linked_ptr and read its underlying
-// raw pointer (e.g. via get()) concurrently, and
-// - it's safe to write to two linked_ptrs that point to the same
-// shared object concurrently.
-// TODO(wan@google.com): rename this to safe_linked_ptr to avoid
-// confusion with normal linked_ptr.

-// with a particular generator, Google Test creates and runs tests

-// class FooTest : public TestWithParam<int> { ... };

-// Range(start, end)

-// start+2, ..., }.
-// Range(start, end, step)
-// - returns a generator producing a sequence of values {start, start+step,
-// start+step+step, ..., }.
-// * The generated sequences never include end. For example, Range(1, 5)
-// returns a generator producing a sequence {1, 2, 3, 4}. Range(1, 9, 2)
-// returns a generator producing {1, 3, 5, 7}.
-// * start and end must have the same type. That type may be any integral or
-// floating-point type or a user defined type satisfying these conditions:
-// * It must be assignable (have operator=() defined).
-// * It must have operator+() (operator+(int-compatible type) for
-// two-operand version).
-// * It must have operator<() defined.
-// Elements in the resulting sequences will also have that type.
-// * Condition start < end must be satisfied in order for resulting sequences
-// to contain any elements.

-// the macro to parse correctly.
-typedef testing::Types<char, int, unsigned int> MyTypes;
-TYPED_TEST_CASE(FooTest, MyTypes);
-// If the type list contains only one type, you can write that type
-// directly without Types<...>:
-// TYPED_TEST_CASE(FooTest, int);
-// Then, use TYPED_TEST() instead of TEST_F() to define as many typed
-// tests for this test case as you want.

-// 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:
-// Next, declare that you will define a type-parameterized test case
-// (the _P suffix is for "parameterized" or "pattern", whichever you
-// prefer):
-TYPED_TEST_CASE_P(FooTest);
-// Then, use TYPED_TEST_P() to define as many type-parameterized tests
-// for this type-parameterized test case as you want.

-// 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
-// Actual: false
-// 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:
-// return testing::AssertionSuccess() << n << " is even";
-// 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) {
-// return testing::AssertionFailure()
-// << "Expected: " << expr << " is even\n Actual: it's " << n;
-// If Foo() returns 5, you will see the following message:

-// Compile-time assertion for type equality.
-// StaticAssertTypeEq<type1, type2>() compiles iff type1 and type2 are
-// the same type. The value it returns is not interesting.
-// Instead of making StaticAssertTypeEq a class template, we make it a
-// function template that invokes a helper class template. This
-// prevents a user from misusing StaticAssertTypeEq<T1, T2> by
-// defining objects of that type.
-// When used inside a method of a class template,
-// StaticAssertTypeEq<T1, T2>() is effective ONLY IF the method is
-// instantiated. For example, given:
-// template <typename T> class Foo {
-// void Bar() { testing::StaticAssertTypeEq<int, T>(); }
-// the code:
-// void Test1() { Foo<bool> foo; }
-// will NOT generate a compiler error, as Foo<bool>::Bar() is never
-// actually instantiated. Instead, you need:
-// void Test2() { Foo<bool> foo; foo.Bar(); }
-// to cause a compiler error.
-bool StaticAssertTypeEq() {
- (void)internal::StaticAssertTypeEqHelper<T1, T2>();
-// Defines a test.
-// The first parameter is the name of the test case, and the second
-// parameter is the name of the test within the test case.
-// The convention is to end the test case name with "Test". For
-// example, a test case for the Foo class can be named FooTest.
-// The user should put his test code between braces after using this
-// macro. Example:
-// TEST(FooTest, InitializesCorrectly) {
-// EXPECT_TRUE(foo.StatusIsOK());
-// Note that we call GetTestTypeId() instead of GetTypeId<
-// ::testing::Test>() here to get the type ID of testing::Test. This
-// is to work around a suspected linker bug when using Google Test as
-// a framework on Mac OS X. The bug causes GetTypeId<
-// ::testing::Test>() to return different values depending on whether
-// the call is from the Google Test framework itself or from user test
-// code. GetTestTypeId() is guaranteed to always return the same
-// value, as it always calls GetTypeId<>() from the Google Test
