//   GTEST_HAS_GLOBAL_WSTRING - Define it to 1/0 to indicate that ::string
//                              is/isn't available (some systems define

//                              used.  Unused when the user sets
//                              GTEST_HAS_TR1_TUPLE to 0.
//   GTEST_LINKED_AS_SHARED_LIBRARY
//                            - Define to 1 when compiling tests that use
//                              Google Test as a shared library (known as
//                              DLL on Windows).

//                              as a shared library.

// This header defines the following utilities:
//
// Macros indicating the current platform (defined to 1 if compiled on
// the given platform; otherwise undefined):
//   GTEST_OS_AIX      - IBM AIX

//   GTEST_OS_ZOS      - z/OS
//
// Among the platforms, Cygwin, Linux, Max 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!).
//
// Note that it is possible that none of the GTEST_OS_* macros are defined.
//
// Macros indicating available Google Test features (defined to 1 if
// the corresponding feature is supported; otherwise undefined):
//   GTEST_HAS_COMBINE      - the Combine() function (for value-parameterized
//                            tests)

//                            define themselves.
//   GTEST_USES_SIMPLE_RE   - our own simple regex is used;
//                            the above two are mutually exclusive.
//   GTEST_CAN_COMPARE_NULL - accepts untyped NULL in EXPECT_EQ().
//
// 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.

//                         synchronization primitives have real implementations
//                         and Google Test is thread-safe; or 0 otherwise.
//
// Template meta programming:
//   is_pointer     - as in TR1; needed on Symbian and IBM XL C/C++ only.
//   IteratorTraits - partial implementation of std::iterator_traits, which
//                    is not available in libCstd when compiled with Sun C++.
//
// Smart pointers:
//   scoped_ptr     - as in TR2.
//
// Regular expressions:
//   RE             - a simple regular expression class using the POSIX
//                    Extended Regular Expression syntax on UNIX-like
//                    platforms, or a reduced regular exception syntax on
//                    other platforms, including Windows.
//
// Logging:
//   GTEST_LOG_()   - logs messages at the specified severity level.

//   CaptureStderr()     - starts capturing stderr.
//   GetCapturedStderr() - stops capturing stderr and returns the captured
//                         string.
//
// Integer types:
//   TypeWithSize   - maps an integer to a int type.
//   Int32, UInt32, Int64, UInt64, TimeInMillis
//                  - integers of known sizes.
//   BiggestInt     - the biggest signed integer type.
//
// Command-line utilities:
//   GTEST_FLAG()       - references a flag.
//   GTEST_DECLARE_*()  - declares a flag.
//   GTEST_DEFINE_*()   - defines a flag.
//   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 environment variable.

//
// - The simpler definition
//
//    #define GTEST_COMPILE_ASSERT_(expr, msg) typedef char msg[(expr) ? 1 : -1]
//
//   does not work, as gcc supports variable-length arrays whose sizes
//   are determined at run-time (this is gcc's extension and not part
//   of the C++ standard).  As a result, gcc fails to reject the
//   following code with the simple definition:
//
//     int foo;
//     GTEST_COMPILE_ASSERT_(foo, msg); // not supposed to compile as foo is
//                                      // not a compile-time constant.
//
// - By using the type CompileAssert<(bool(expr))>, we ensures that
//   expr is a compile-time constant.  (Template arguments must be
//   determined at compile-time.)
//
// - The outter parentheses in CompileAssert<(bool(expr))> are necessary
//   to work around a bug in gcc 3.4.4 and 4.0.1.  If we had written
//
//     CompileAssert<bool(expr)>
//
//   instead, these compilers will refuse to compile

//
//   (They seem to think the ">" in "5 > 0" marks the end of the
//   template argument list.)
//
// - The array size is (bool(expr) ? 1 : -1), instead of simply
//
//     ((expr) ? 1 : -1).

// how do you know the pointer is really of type SubclassOfFoo?  It

// We don't want to require the users to write TypesN<...> directly,
// as that would require them to count the length.  Types<...> is much
// easier to write, but generates horrible messages when there is a
// compiler error, as gcc insists on printing out each template
// argument, even if it has the default value (this means Types<int>
// will appear as Types<int, None, None, ..., None> in the compiler
// errors).
//
// Our solution is to combine the best part of the two approaches: a
// user would write Types<T1, ..., TN>, and Google Test will translate
// that to TypesN<T1, ..., TN> internally to make error messages
// readable.  The translation is done by the 'type' member of the
// Types template.

// We don't want to require the users to write TemplatesN<...> directly,
// as that would require them to count the length.  Templates<...> is much
// easier to write, but generates horrible messages when there is a
// compiler error, as gcc insists on printing out each template
// argument, even if it has the default value (this means Templates<list>
// will appear as Templates<list, NoneT, NoneT, ..., NoneT> in the compiler
// errors).
//
// Our solution is to combine the best part of the two approaches: a
// user would write Templates<T1, ..., TN>, and Google Test will translate
// that to TemplatesN<T1, ..., TN> internally to make error messages
// readable.  The translation is done by the 'type' member of the
// Templates template.

// 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!");
//
// 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), 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.
//
// TODO(wan@google.com): make thread-safe death tests search the PATH.

//   1. You stream a bunch of values to a Message object.

//
// For example;

// 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_CASE_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 case
// each with parameter values "meeny", "miny", and "moe".

                        FooTest,
                        Values("meeny", "miny", "moe"));

// To distinguish different instances of the pattern, (yes, you
// can instantiate it more then once) the first argument to the
// INSTANTIATE_TEST_CASE_P macro is a prefix that will be added to the
// actual test case 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"

//
// Please note that INSTANTIATE_TEST_CASE_P will instantiate all tests
// in the given test case, whether their definitions come before or
// AFTER the INSTANTIATE_TEST_CASE_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

// A parameterized test fixture must be derived from testing::Test and from

// 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.
}

TEST_P(DerivedTest, DoesBlah) {
  // GetParam works just the same here as if you inherit from TestWithParam.
  EXPECT_TRUE(foo.Blah(GetParam()));

//
// 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.

// 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.
//
// 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.

// Functions producing parameter generators.
//
// Google Test uses these generators to produce parameters for value-
// parameterized tests. When a parameterized test case is instantiated
// with a particular generator, Google Test creates and runs tests
// for each element in the sequence produced by the generator.
//
// In the following sample, tests from test case FooTest are instantiated
// each three times with parameter values 3, 5, and 8:
//
// class FooTest : public TestWithParam<int> { ... };
//
// TEST_P(FooTest, TestThis) {

// Range() returns generators providing sequences of values in a range.
//
// Synopsis:
// Range(start, end)
//   - returns a generator producing a sequence of values {start, start+1,
//     start+2, ..., }.
// Range(start, end, step)
//   - returns a generator producing a sequence of values {start, start+step,
//     start+step+step, ..., }.
// Notes:
//   * 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.

// ValuesIn(const Container& container)

//
// Please note that ValuesIn copies the values from the containers

// const char* strings[] = {"foo", "bar", "baz"};

//
// This instantiates tests from test case StlStringTest

// Bool() allows generating tests with parameters in a set of (false, true).

// of multiple flags can be tested when several Bool()'s are combined using
// Combine() function.
//
// In the following example all tests in the test case FlagDependentTest
// will be instantiated twice with parameters false and true.

// Combine() allows the user to combine two or more sequences to produce
// values of a Cartesian product of those sequences' elements.
//
// Synopsis:
// Combine(gen1, gen2, ..., genN)
//   - returns a generator producing sequences with elements coming from
//     the Cartesian product of elements from the sequences generated by
//     gen1, gen2, ..., genN. The sequence elements will have a type of
//     tuple<T1, T2, ..., TN> where T1, T2, ..., TN are the types
//     of elements from sequences produces by gen1, gen2, ..., genN.
//
// Combine can have up to 10 arguments. This number is currently limited
// by the maximum number of elements in the tuple implementation used by Google
// Test.
//
// Example:
//
// This will instantiate tests in test case AnimalTest each one with
// the parameter values tuple("cat", BLACK), tuple("cat", WHITE),
// tuple("dog", BLACK), and tuple("dog", WHITE):
//
// enum Color { BLACK, GRAY, WHITE };
// class AnimalTest
//     : public testing::TestWithParam<tuple<const char*, Color> > {...};
//
// TEST_P(AnimalTest, AnimalLooksNice) {...}

//                                 Values(BLACK, WHITE)));
//
// This will instantiate tests in FlagDependentTest with all variations of two
// Boolean flags:
//
// class FlagDependentTest
//     : public testing::TestWithParam<tuple<bool, bool> > {
//   virtual void SetUp() {
//     // Assigns external_flag_1 and external_flag_2 values from the tuple.
//     tie(external_flag_1, external_flag_2) = GetParam();
//   }
// };
//
// TEST_P(FlagDependentTest, TestFeature1) {
//   // Test your code using external_flag_1 and external_flag_2 here.

// This header implements typed tests and type-parameterized tests.

// 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 case, 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_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.
TYPED_TEST(FooTest, DoesBlah) {
  // Inside a test, refer to TypeParam to get the type parameter.
  // Since we are inside a derived class template, C++ requires use 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) { ... }

#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 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.
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 case name; the rest are the names of the tests in this test
// case.
REGISTER_TYPED_TEST_CASE_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 case name.  Remember to pick unique prefixes for
// different instances.

// 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

//
// Note:
//
//   1. It is possible to make a user-defined type work with
//   {ASSERT|EXPECT}_??(), but that requires overloading the
//   comparison operators and is thus discouraged by the Google C++
//   Usage Guide.  Therefore, you are advised to use the
//   {ASSERT|EXPECT}_TRUE() macro to assert that two objects are
//   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
//   are related, not how their content is related.  To compare two C
//   strings by content, use {ASSERT|EXPECT}_STR*().
//
//   3. {ASSERT|EXPECT}_EQ(expected, actual) is preferred to
//   {ASSERT|EXPECT}_TRUE(expected == actual), as the former tells you
//   what the actual value is when it fails, and similarly for the
//   other comparisons.
//
//   4. Do not depend on the order in which {ASSERT|EXPECT}_??()
//   evaluate their arguments, which is undefined.
