// 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

// succeeds is not a factor in deciding whether an explanation is

// 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".
INSTANTIATE_TEST_CASE_P(InstantiationName,
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"
// * 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_CASE_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_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
// 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.
}
TEST_P(DerivedTest, DoesBlah) {
// GetParam works just the same here as if you inherit from TestWithParam.
EXPECT_TRUE(foo.Blah(GetParam()));

# 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:
### Flag related macros:
* `GTEST_FLAG(flag_name)`
* `GTEST_USE_OWN_FLAGFILE_FLAG_` - Define to 0 when the system provides its
own flagfile flag parsing.
* `GTEST_DECLARE_bool_(name)`
* `GTEST_DECLARE_int32_(name)`
* `GTEST_DECLARE_string_(name)`
* `GTEST_DEFINE_bool_(name, default_val, doc)`
* `GTEST_DEFINE_int32_(name, default_val, doc)`
* `GTEST_DEFINE_string_(name, default_val, doc)`
### 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.

// on a system that does not support death tests and be sure that it will
// compile on a death-test supporting system.
//
// 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 iff 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

//
// 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.
