// 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.
//
// Asserts that a given `statement` causes the program to exit, with an
// integer exit status that satisfies `predicate`, and emitting error output

//
// In practice, this can be used to test functions that utilize the

//
// int DieInDebugOr12(int* sideeffect) {
// if (sideeffect) {
// *sideeffect = 12;

//
// This will assert that DieInDebugReturn12InOpt() crashes in debug
// mode, usually due to a DCHECK or LOG(DFATAL), but returns the
// appropriate fallback value (12 in this case) in opt mode. If you
// need to test that a function has appropriate side-effects in opt
// mode, include assertions against the side-effects. A general
// pattern for this is:
//
// EXPECT_DEBUG_DEATH({

// This macro is used for implementing macros such as

// death tests are not supported. Those macros must compile on such systems
// if and only if EXPECT_DEATH and ASSERT_DEATH compile with the same parameters
// 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

// 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.

// Inside a test, access the test parameter with the GetParam() method
// of the TestWithParam<T> class:

...
}

...
}
// 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":

// * 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.

// 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 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);
//
// Similar to the optional argument of TYPED_TEST_SUITE above,

# 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)`
### Underlying library support features
* `GTEST_HAS_CXXABI_H_`
### Exporting API symbols:
* `GTEST_API_` - Specifier for exported symbols.
## Header `gtest-printers.h`
* See documentation at `gtest/gtest-printers.h` for details on how to define a
custom printer.
