Based on the -xUnit architecture. Supports automatic test discovery, a rich set of -assertions, user-defined assertions, death tests, fatal and non-fatal -failures, various options for running the tests, and XML test report -generation. - -Please see the project page above for more information as well as the -mailing list for questions, discussions, and development. There is -also an IRC channel on OFTC (irc.oftc.net) #gtest available. Please -join us! - -Requirements for End Users --------------------------- - -Google Test is designed to have fairly minimal requirements to build -and use with your projects, but there are some. Currently, we support -Linux, Windows, Mac OS X, and Cygwin. We will also make our best -effort to support other platforms (e.g. Solaris, AIX, and z/OS). -However, since core members of the Google Test project have no access -to these platforms, Google Test may have outstanding issues there. If -you notice any problems on your platform, please notify -googletestframew...@googlegroups.com. Patches for fixing them are -even more welcome! - -### Linux Requirements ### - -These are the base requirements to build and use Google Test from a source -package (as described below): - * GNU-compatible Make or gmake - * POSIX-standard shell - * POSIX(-2) Regular Expressions (regex.h) - * A C++98-standard-compliant compiler - -### Windows Requirements ### - - * Microsoft Visual C++ 7.1 or newer - -### Cygwin Requirements ### - - * Cygwin 1.5.25-14 or newer - -### Mac OS X Requirements ### - - * Mac OS X 10.4 Tiger or newer - * Developer Tools Installed - -Also, you'll need CMake 2.6.4 or higher if you want to build the -samples using the provided CMake script, regardless of the platform. - -Requirements for Contributors ------------------------------ - -We welcome patches. If you plan to contribute a patch, you need to -build Google Test and its own tests from an SVN checkout (described -below), which has further requirements: - - * Python version 2.3 or newer (for running some of the tests and - re-generating certain source files from templates) - * CMake 2.6.4 or newer - -Getting the Source ------------------- - -There are two primary ways of getting Google Test's source code: you -can download a stable source release in your preferred archive format, -or directly check out the source from our Subversion (SVN) repositary. -The SVN checkout requires a few extra steps and some extra software -packages on your system, but lets you track the latest development and -make patches much more easily, so we highly encourage it. - -### Source Package ### - -Google Test is released in versioned source packages which can be -downloaded from the download page [1]. Several different archive -formats are provided, but the only difference is the tools used to -manipulate them, and the size of the resulting file. Download -whichever you are most comfortable with. - - [1] http://code.google.com/p/googletest/downloads/list - -Once the package is downloaded, expand it using whichever tools you -prefer for that type. This will result in a new directory with the -name "gtest-X.Y.Z" which contains all of the source code. Here are -some examples on Linux: - - tar -xvzf gtest-X.Y.Z.tar.gz - tar -xvjf gtest-X.Y.Z.tar.bz2 - unzip gtest-X.Y.Z.zip - -### SVN Checkout ### - -To check out the main branch (also known as the "trunk") of Google -Test, run the following Subversion command: - - svn checkout http://googletest.googlecode.com/svn/trunk/ gtest-svn - -Setting up the Build --------------------- - -To build Google Test and your tests that use it, you need to tell your -build system where to find its headers and source files. The exact -way to do it depends on which build system you use, and is usually -straightforward. - -### Generic Build Instructions ### - -Suppose you put Google Test in directory ${GTEST_DIR}. To build it, -create a library build target (or a project as called by Visual Studio -and Xcode) to compile - - ${GTEST_DIR}/src/gtest-all.cc - -with ${GTEST_DIR}/include in the system header search path and ${GTEST_DIR} -in the normal header search path. Assuming a Linux-like system and gcc, -something like the following will do: - - g++ -isystem ${GTEST_DIR}/include -I${GTEST_DIR} \ - -pthread -c ${GTEST_DIR}/src/gtest-all.cc - ar -rv libgtest.a gtest-all.o - -(We need -pthread as Google Test uses threads.) - -Next, you should compile your test source file with -${GTEST_DIR}/include in the system header search path, and link it -with gtest and any other necessary libraries: - - g++ -isystem ${GTEST_DIR}/include -pthread path/to/your_test.cc libgtest.a \ - -o your_test - -As an example, the make/ directory contains a Makefile that you can -use to build Google Test on systems where GNU make is available -(e.g. Linux, Mac OS X, and Cygwin). It doesn't try to build Google -Test's own tests. Instead, it just builds the Google Test library and -a sample test. You can use it as a starting point for your own build -script. - -If the default settings are correct for your environment, the -following commands should succeed: - - cd ${GTEST_DIR}/make - make - ./sample1_unittest - -If you see errors, try to tweak the contents of make/Makefile to make -them go away. There are instructions in make/Makefile on how to do -it. - -### Using CMake ### - -Google Test comes with a CMake build script (CMakeLists.txt) that can -be used on a wide range of platforms ("C" stands for cross-platofrm.). -If you don't have CMake installed already, you can download it for -free from http://www.cmake.org/. - -CMake works by generating native makefiles or build projects that can -be used in the compiler environment of your choice. The typical -workflow starts with: - - mkdir mybuild # Create a directory to hold the build output. - cd mybuild - cmake ${GTEST_DIR} # Generate native build scripts. - -If you want to build Google Test's samples, you should replace the -last command with - - cmake -Dgtest_build_samples=ON ${GTEST_DIR} - -If you are on a *nix system, you should now see a Makefile in the -current directory. Just type 'make' to build gtest. - -If you use Windows and have Vistual Studio installed, a gtest.sln file -and several .vcproj files will be created. You can then build them -using Visual Studio. - -On Mac OS X with Xcode installed, a .xcodeproj file will be generated. - -### Legacy Build Scripts ### - -Before settling on CMake, we have been providing hand-maintained build -projects/scripts for Visual Studio, Xcode, and Autotools. While we -continue to provide them for convenience, they are not actively -maintained any more. We highly recommend that you follow the -instructions in the previous two sections to integrate Google Test -with your existing build system. - -If you still need to use the legacy build scripts, here's how: - -The msvc\ folder contains two solutions with Visual C++ projects. -Open the gtest.sln or gtest-md.sln file using Visual Studio, and you -are ready to build Google Test the same way you build any Visual -Studio project. Files that have names ending with -md use DLL -versions of Microsoft runtime libraries (the /MD or the /MDd compiler -option). Files without that suffix use static versions of the runtime -libraries (the /MT or the /MTd option). Please note that one must use -the same option to compile both gtest and the test code. If you use -Visual Studio 2005 or above, we recommend the -md version as /MD is -the default for new projects in these versions of Visual Studio. - -On Mac OS X, open the gtest.xcodeproj in the xcode/ folder using -Xcode. Build the "gtest" target. The universal binary framework will -end up in your selected build directory (selected in the Xcode -"Preferences..." -> "Building" pane and defaults to xcode/build). -Alternatively, at the command line, enter: - - xcodebuild - -This will build the "Release" configuration of gtest.framework in your -default build location. See the "xcodebuild" man page for more -information about building different configurations and building in -different locations. - -If you wish to use the Google Test Xcode project with Xcode 4.x and -above, you need to either: - * update the SDK configuration options in xcode/Config/General.xconfig. - Comment options SDKROOT, MACOS_DEPLOYMENT_TARGET, and GCC_VERSION. If - you choose this route you lose the ability to target earlier versions - of MacOS X. - * Install an SDK for an earlier version. This doesn't appear to be - supported by Apple, but has been reported to work - (http://stackoverflow.com/questions/5378518). - -Tweaking Google Test --------------------- - -Google Test 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 Google Test 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. - -### Choosing a TR1 Tuple Library ### - -Some Google Test features require the C++ Technical Report 1 (TR1) -tuple library, which is not yet available with all compilers. The -good news is that Google Test implements a subset of TR1 tuple that's -enough for its own need, and will automatically use this when the -compiler doesn't provide TR1 tuple. - -Usually you don't need to care about which tuple library Google Test -uses. However, if your project already uses TR1 tuple, you need to -tell Google Test to use the same TR1 tuple library the rest of your -project uses, or the two tuple implementations will clash. To do -that, add - - -DGTEST_USE_OWN_TR1_TUPLE=0 - -to the compiler flags while compiling Google Test and your tests. If -you want to force Google Test to use its own tuple library, just add - - -DGTEST_USE_OWN_TR1_TUPLE=1 - -to the compiler flags instead. - -If you don't want Google Test to use tuple at all, add - - -DGTEST_HAS_TR1_TUPLE=0 - -and all features using tuple will be disabled. - -### Multi-threaded Tests ### - -Google Test 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 Google Test 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 Google Test 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 or the deprecated Autotools -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) ### - -Google Test is compact, so most users can build and link it as a -static library for the simplicity. You can choose to use Google Test -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 Google Test as a -shared library. Otherwise a future release of Google Test 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 Google Test macro clashes with another -library, you can force Google Test to rename its macro to avoid the -conflict. - -Specifically, if both Google Test and some other code define macro -FOO, you can add - - -DGTEST_DONT_DEFINE_FOO=1 - -to the compiler flags to tell Google Test 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. - -Upgrating from an Earlier Version ---------------------------------- - -We strive to keep Google Test releases backward compatible. -Sometimes, though, we have to make some breaking changes for the -users' long-term benefits. This section describes what you'll need to -do if you are upgrading from an earlier version of Google Test. - -### Upgrading from 1.3.0 or Earlier ### - -You may need to explicitly enable or disable Google Test's own TR1 -tuple library. See the instructions in section "Choosing a TR1 Tuple -Library". - -### Upgrading from 1.4.0 or Earlier ### - -The Autotools build script (configure + make) is no longer officially -supportted. You are encouraged to migrate to your own build system or -use CMake. If you still need to use Autotools, you can find -instructions in the README file from Google Test 1.4.0. - -On platforms where the pthread library is available, Google Test uses -it in order to be thread-safe. See the "Multi-threaded Tests" section -for what this means to your build script. - -If you use Microsoft Visual C++ 7.1 with exceptions disabled, Google -Test will no longer compile. This should affect very few people, as a -large portion of STL (including <string>) doesn't compile in this mode -anyway. We decided to stop supporting it in order to greatly simplify -Google Test's implementation. - -Developing Google Test ----------------------- - -This section discusses how to make your own changes to Google Test. - -### Testing Google Test Itself ### - -To make sure your changes work as intended and don't break existing -functionality, you'll want to compile and run Google Test's own tests. -For that you can use CMake: - - mkdir mybuild - cd mybuild - cmake -Dgtest_build_tests=ON ${GTEST_DIR} - -Make sure you have Python installed, as some of Google Test's tests -are written in Python. If the cmake command complains about not being -able to find Python ("Could NOT find PythonInterp (missing: -PYTHON_EXECUTABLE)"), try telling it explicitly where your Python -executable can be found: - - cmake -DPYTHON_EXECUTABLE=path/to/python -Dgtest_build_tests=ON ${GTEST_DIR} - -Next, you can build Google Test and all of its own tests. On *nix, -this is usually done by 'make'. To run the tests, do - - make test - -All tests should pass. - -### Regenerating Source Files ### - -Some of Google Test's source files are generated from templates (not -in the C++ sense) using a script. A template file is named FOO.pump, -where FOO is the name of the file it will generate. For example, the -file include/gtest/internal/gtest-type-util.h.pump is used to generate -gtest-type-util.h in the same directory. - -Normally you don't need to worry about regenerating the source files, -unless you need to modify them. In that case, you should modify the -corresponding .pump files instead and run the pump.py Python script to -regenerate them. You can find pump.py in the scripts/ directory. -Read the Pump manual [2] for how to use it. - - [2] http://code.google.com/p/googletest/wiki/PumpManual - -### Contributing a Patch ### - -We welcome patches. Please read the Google Test developer's guide [3] -for how you can contribute. In particular, make sure you have signed -the Contributor License Agreement, or we won't be able to accept the -patch. - - [3] http://code.google.com/p/googletest/wiki/GoogleTestDevGuide - -Happy testing!
