If this -is not feasible, for example in a C project using GoogleTest for validation, -then it can be specified by adding it to the options for cmake via the -`DCMAKE_CXX_FLAGS` option. - -### Tweaking GoogleTest - -GoogleTest can be used in diverse environments. The default configuration may -not work (or may not work well) out of the box in some environments. However, -you can easily tweak GoogleTest by defining control macros on the compiler -command line. Generally, these macros are named like `GTEST_XYZ` and you define -them to either 1 or 0 to enable or disable a certain feature. - -We list the most frequently used macros below. For a complete list, see file -[include/gtest/internal/gtest-port.h](https://github.com/google/googletest/blob/master/googletest/include/gtest/internal/gtest-port.h). - -### Multi-threaded Tests - -GoogleTest is thread-safe where the pthread library is available. After -`#include "gtest/gtest.h"`, you can check the -`GTEST_IS_THREADSAFE` macro to see whether this is the case (yes if the macro is -`#defined` to 1, no if it's undefined.). - -If GoogleTest doesn't correctly detect whether pthread is available in your -environment, you can force it with - - -DGTEST_HAS_PTHREAD=1 - -or - - -DGTEST_HAS_PTHREAD=0 - -When GoogleTest uses pthread, you may need to add flags to your compiler and/or -linker to select the pthread library, or you'll get link errors. If you use the -CMake script, this is taken care of for you. If you use your own build script, -you'll need to read your compiler and linker's manual to figure out what flags -to add. - -### As a Shared Library (DLL) - -GoogleTest is compact, so most users can build and link it as a static library -for the simplicity. You can choose to use GoogleTest as a shared library (known -as a DLL on Windows) if you prefer. - -To compile *gtest* as a shared library, add - - -DGTEST_CREATE_SHARED_LIBRARY=1 - -to the compiler flags. You'll also need to tell the linker to produce a shared -library instead - consult your linker's manual for how to do it. - -To compile your *tests* that use the gtest shared library, add - - -DGTEST_LINKED_AS_SHARED_LIBRARY=1 - -to the compiler flags. - -Note: while the above steps aren't technically necessary today when using some -compilers (e.g. GCC), they may become necessary in the future, if we decide to -improve the speed of loading the library (see -<http://gcc.gnu.org/wiki/Visibility> for details). Therefore you are recommended -to always add the above flags when using GoogleTest as a shared library. -Otherwise a future release of GoogleTest may break your build script. - -### Avoiding Macro Name Clashes - -In C++, macros don't obey namespaces. Therefore two libraries that both define a -macro of the same name will clash if you `#include` both definitions. In case a -GoogleTest macro clashes with another library, you can force GoogleTest to -rename its macro to avoid the conflict. - -Specifically, if both GoogleTest and some other code define macro FOO, you can -add - - -DGTEST_DONT_DEFINE_FOO=1 - -to the compiler flags to tell GoogleTest to change the macro's name from `FOO` -to `GTEST_FOO`. Currently `FOO` can be `FAIL`, `SUCCEED`, or `TEST`. For -example, with `-DGTEST_DONT_DEFINE_TEST=1`, you'll need to write - - GTEST_TEST(SomeTest, DoesThis) { ... } - -instead of - - TEST(SomeTest, DoesThis) { ... } - -in order to define a test. +### Generic Build Instructions + +#### Setup + +To build GoogleTest and your tests that use it, you need to tell your build +system where to find its headers and source files.

If this +is not feasible, for example in a C project using GoogleTest for validation, +then it can be specified by adding it to the options for cmake via the +`DCMAKE_CXX_FLAGS` option. + +### Tweaking GoogleTest + +GoogleTest can be used in diverse environments. The default configuration may +not work (or may not work well) out of the box in some environments. However, +you can easily tweak GoogleTest by defining control macros on the compiler +command line. Generally, these macros are named like `GTEST_XYZ` and you define +them to either 1 or 0 to enable or disable a certain feature. + +We list the most frequently used macros below. For a complete list, see file +[include/gtest/internal/gtest-port.h](https://github.com/google/googletest/blob/master/googletest/include/gtest/internal/gtest-port.h). + +### Multi-threaded Tests + +GoogleTest is thread-safe where the pthread library is available. After +`#include "gtest/gtest.h"`, you can check the +`GTEST_IS_THREADSAFE` macro to see whether this is the case (yes if the macro is +`#defined` to 1, no if it's undefined.). + +If GoogleTest doesn't correctly detect whether pthread is available in your +environment, you can force it with + + -DGTEST_HAS_PTHREAD=1 + +or + + -DGTEST_HAS_PTHREAD=0 + +When GoogleTest uses pthread, you may need to add flags to your compiler and/or +linker to select the pthread library, or you'll get link errors. If you use the +CMake script, this is taken care of for you. If you use your own build script, +you'll need to read your compiler and linker's manual to figure out what flags +to add. + +### As a Shared Library (DLL) + +GoogleTest is compact, so most users can build and link it as a static library +for the simplicity. You can choose to use GoogleTest as a shared library (known +as a DLL on Windows) if you prefer. + +To compile *gtest* as a shared library, add + + -DGTEST_CREATE_SHARED_LIBRARY=1 + +to the compiler flags. You'll also need to tell the linker to produce a shared +library instead - consult your linker's manual for how to do it. + +To compile your *tests* that use the gtest shared library, add + + -DGTEST_LINKED_AS_SHARED_LIBRARY=1 + +to the compiler flags. + +Note: while the above steps aren't technically necessary today when using some +compilers (e.g. GCC), they may become necessary in the future, if we decide to +improve the speed of loading the library (see +<http://gcc.gnu.org/wiki/Visibility> for details). Therefore you are recommended +to always add the above flags when using GoogleTest as a shared library. +Otherwise a future release of GoogleTest may break your build script. + +### Avoiding Macro Name Clashes + +In C++, macros don't obey namespaces. Therefore two libraries that both define a +macro of the same name will clash if you `#include` both definitions. In case a +GoogleTest macro clashes with another library, you can force GoogleTest to +rename its macro to avoid the conflict. + +Specifically, if both GoogleTest and some other code define macro FOO, you can +add + + -DGTEST_DONT_DEFINE_FOO=1 + +to the compiler flags to tell GoogleTest to change the macro's name from `FOO` +to `GTEST_FOO`. Currently `FOO` can be `FAIL`, `SUCCEED`, or `TEST`. For +example, with `-DGTEST_DONT_DEFINE_TEST=1`, you'll need to write + + GTEST_TEST(SomeTest, DoesThis) { ... } + +instead of + + TEST(SomeTest, DoesThis) { ... } + +in order to define a test. diff --git a/contrib/restricted/googletest/googletest/gtest_main/ya.make b/contrib/restricted/googletest/googletest/gtest_main/ya.make index 444c91c6d8..98edf7262a 100644 --- a/contrib/restricted/googletest/googletest/gtest_main/ya.make +++ b/contrib/restricted/googletest/googletest/gtest_main/ya.make @@ -12,14 +12,14 @@ LICENSE(BSD-3-Clause) LICENSE_TEXTS(.yandex_meta/licenses.list.txt) PEERDIR( - contrib/restricted/googletest/googletest + contrib/restricted/googletest/googletest +) + +ADDINCL( + GLOBAL contrib/restricted/googletest/googletest/include + contrib/restricted/googletest/googletest ) -ADDINCL( - GLOBAL contrib/restricted/googletest/googletest/include - contrib/restricted/googletest/googletest -) - NO_COMPILER_WARNINGS() NO_UTIL() @@ -30,7 +30,7 @@ CFLAGS( GLOBAL -DGTEST_HAS_STD_WSTRING=1 ) -SRCDIR(contrib/restricted/googletest/googletest/src) +SRCDIR(contrib/restricted/googletest/googletest/src) SRCS( GLOBAL gtest_main.cc diff --git a/contrib/restricted/googletest/googletest/include/gtest/gtest-death-test.h b/contrib/restricted/googletest/googletest/include/gtest/gtest-death-test.h index 3cfe2fe17f..9b4d4d1337 100644 --- a/contrib/restricted/googletest/googletest/include/gtest/gtest-death-test.h +++ b/contrib/restricted/googletest/googletest/include/gtest/gtest-death-test.h @@ -26,17 +26,17 @@ // THEORY OF LIABILITY, WHETHER IN CONTRACT, STRICT LIABILITY, OR TORT // (INCLUDING NEGLIGENCE OR OTHERWISE) ARISING IN ANY WAY OUT OF THE USE // OF THIS SOFTWARE, EVEN IF ADVISED OF THE POSSIBILITY OF SUCH DAMAGE. - + // -// The Google C++ Testing and Mocking Framework (Google Test) +// The Google C++ Testing and Mocking Framework (Google Test) // // This header file defines the public API for death tests.
