// Environment-describing macros
|
|
// -----------------------------
|
|
//
|
|
// Google Test can be used in many different environments. Macros in
|
|
// this section tell Google Test what kind of environment it is being
|
|
// used in, such that Google Test can provide environment-specific
|
|
// features and implementations.
|
|
//
|
|
// Google Test tries to automatically detect the properties of its
|
|
// environment, so users usually don't need to worry about these
|
|
// macros. However, the automatic detection is not perfect.
|
|
// Sometimes it's necessary for a user to define some of the following
|
|
// macros in the build script to override Google Test's decisions.
|
|
//
|
|
// If the user doesn't define a macro in the list, Google Test will
|
|
// provide a default definition. After this header is #included, all
|
|
// macros in this list will be defined to either 1 or 0.
|
|
//
|
|
// Notes to maintainers:
|
|
// - Each macro here is a user-tweakable knob; do not grow the list
|
|
// lightly.
|
|
// - Use #if to key off these macros. Don't use #ifdef or "#if
|
|
// defined(...)", which will not work as these macros are ALWAYS
|
|
// defined.
|
|
//
|
|
// GTEST_HAS_CLONE - Define it to 1/0 to indicate that clone(2)
|
|
// is/isn't available.
|
|
// GTEST_HAS_EXCEPTIONS - Define it to 1/0 to indicate that exceptions
|
|
// are enabled.
|
|
// GTEST_HAS_GLOBAL_STRING - Define it to 1/0 to indicate that ::string
|
|
// is/isn't available
|
|
// GTEST_HAS_GLOBAL_WSTRING - Define it to 1/0 to indicate that ::wstring
|
|
// is/isn't available
|
|
// GTEST_HAS_POSIX_RE - Define it to 1/0 to indicate that POSIX regular
|
|
// expressions are/aren't available.
|
|
// GTEST_HAS_PTHREAD - Define it to 1/0 to indicate that <pthread.h>
|
|
// is/isn't available.
|
|
// GTEST_HAS_RTTI - Define it to 1/0 to indicate that RTTI is/isn't
|
|
// enabled.
|
|
// GTEST_HAS_STD_WSTRING - Define it to 1/0 to indicate that
|
|
// std::wstring does/doesn't work (Google Test can
|
|
// be used where std::wstring is unavailable).
|
|
// GTEST_HAS_SEH - Define it to 1/0 to indicate whether the
|
|
// compiler supports Microsoft's "Structured
|
|
// Exception Handling".
|
|
// GTEST_HAS_STREAM_REDIRECTION
|
|
// - Define it to 1/0 to indicate whether the
|
|
// platform supports I/O stream redirection using
|
|
// dup() and dup2().
|
|
// GTEST_LANG_CXX11 - Define it to 1/0 to indicate that Google Test
|
|
// is building in C++11/C++98 mode.
|
|
// GTEST_LINKED_AS_SHARED_LIBRARY
|
|
// - Define to 1 when compiling tests that use
|
|
// Google Test as a shared library (known as
|
|
// DLL on Windows).
|
|
// GTEST_CREATE_SHARED_LIBRARY
|
|
// - Define to 1 when compiling Google Test itself
|
|
// as a shared library.
|
|
// GTEST_DEFAULT_DEATH_TEST_STYLE
|
|
// - The default value of --gtest_death_test_style.
|
|
// The legacy default has been "fast" in the open

|
// source version since 2008. The recommended value

|
// is "threadsafe", and can be set in

// Platform-indicating macros
|

// --------------------------

|
|
// (a macro is defined to 1 if compiled on the given platform;
|
|
// otherwise UNDEFINED -- it's never defined to 0.). Google Test

|
// defines these macros automatically. Code outside Google Test MUST

// NOT define them.

|
// Feature-indicating macros
|
|
// -------------------------
|
|
//
|
|
// Macros indicating which Google Test features are available (a macro
|
|
// is defined to 1 if the corresponding feature is supported;
|
|
// otherwise UNDEFINED -- it's never defined to 0.). Google Test

|
// defines these macros automatically. Code outside Google Test MUST
|
|
// NOT define them.
|
|
//
|
|
// These macros are public so that portable tests can be written.
|
|
// Such tests typically surround code using a feature with an #if
|
|
// which controls that code. For example:
|
|
//
|
|
// #if GTEST_HAS_DEATH_TEST
|
|
// EXPECT_DEATH(DoSomethingDeadly());
|

// #endif
|
|
//

|
// GTEST_IS_THREADSAFE - Google Test is thread-safe.
|
|
// GOOGLETEST_CM0007 DO NOT DELETE
|
|
// GTEST_USES_POSIX_RE - enhanced POSIX regex is used. Do not confuse with
|
|
// GTEST_HAS_POSIX_RE (see above) which users can
|
|
// define themselves.
|
|
// GTEST_USES_SIMPLE_RE - our own simple regex is used;
|
|
// the above RE\b(s) are mutually exclusive.
|
|
// GTEST_CAN_COMPARE_NULL - accepts untyped NULL in EXPECT_EQ().
|
|
|
|
// Misc public macros
|
|
// ------------------
|
|
//
|
|
// GTEST_FLAG(flag_name) - references the variable corresponding to
|
|
// the given Google Test flag.
|
|
|
|
// Internal utilities
|
|
// ------------------
|
|
//
|
|
// The following macros and utilities are for Google Test's INTERNAL
|
|
// use only. Code outside Google Test MUST NOT USE THEM DIRECTLY.
|
|
//
|
|
// Macros for basic C++ coding:
|
|
// GTEST_AMBIGUOUS_ELSE_BLOCKER_ - for disabling a gcc warning.
|
|
// GTEST_ATTRIBUTE_UNUSED_ - declares that a class' instances or a
|
|
// variable don't have to be used.
|
|
// GTEST_DISALLOW_ASSIGN_ - disables operator=.
|
|
// GTEST_DISALLOW_COPY_AND_ASSIGN_ - disables copy ctor and operator=.
|
|
// GTEST_MUST_USE_RESULT_ - declares that a function's result must be used.
|
|
// GTEST_INTENTIONAL_CONST_COND_PUSH_ - start code section where MSVC C4127 is
|
|
// suppressed (constant conditional).
|
|
// GTEST_INTENTIONAL_CONST_COND_POP_ - finish code section where MSVC C4127
|
|
// is suppressed.
|
|
//
|
|
// C++11 feature wrappers:
|
|
//
|
|
// testing::internal::forward - portability wrapper for std::forward.
|
|
// testing::internal::move - portability wrapper for std::move.
|
|
//
|
|
// Synchronization:
|
|
// Mutex, MutexLock, ThreadLocal, GetThreadCount()
|
|
// - synchronization primitives.
|
|
//
|
|
// 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
|
|
// GOOGLETEST_CM0008 DO NOT DELETE
|
|
// or a reduced regular exception syntax on other
|
|
// platforms, including Windows.
|
|
// Logging:
|
|
// GTEST_LOG_() - logs messages at the specified severity level.
|
|
// LogToStderr() - directs all log messages to stderr.
|
|
// FlushInfoLog() - flushes informational log messages.
|
|
//
|
|
// Stdout and stderr capturing:
|
|
// CaptureStdout() - starts capturing stdout.
|
|
// GetCapturedStdout() - stops capturing stdout and returns the captured
|
|
// string.
|
|
// CaptureStderr() - starts capturing stderr.
|
|
// GetCapturedStderr() - stops capturing stderr and returns the captured
|
|
// string.
|
|
//
|
|
// Integer types:
|
|
// TypeWithSize - maps an integer to a int type.
|
|
// Int32, UInt32, Int64, UInt64, TimeInMillis
|
|
// - integers of known sizes.
|
|
// BiggestInt - the biggest signed integer type.
|
|
//
|
|
// Command-line utilities:
|
|
// 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.
|
|
// StringFromGTestEnv() - parses a string environment variable.

// (In C++11, we simply use static_assert instead of the following)
|

//
|
|
// - GTEST_COMPILE_ASSERT_ works by defining an array type that has -1
|
|
// elements (and thus is invalid) when the expression is false.
|
|
//
|
|
// - 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
