      1 Google C++ Testing Framework
      2 ============================
      3 
      4 http://code.google.com/p/googletest/
      5 
      6 Overview
      7 --------
      8 
      9 Google's framework for writing C++ tests on a variety of platforms
     10 (Linux, Mac OS X, Windows, Windows CE, Symbian, etc).  Based on the
     11 xUnit architecture.  Supports automatic test discovery, a rich set of
     12 assertions, user-defined assertions, death tests, fatal and non-fatal
     13 failures, various options for running the tests, and XML test report
     14 generation.
     15 
     16 Please see the project page above for more information as well as the
     17 mailing list for questions, discussions, and development.  There is
     18 also an IRC channel on OFTC (irc.oftc.net) #gtest available.  Please
     19 join us!
     20 
     21 Requirements for End Users
     22 --------------------------
     23 
     24 Google Test is designed to have fairly minimal requirements to build
     25 and use with your projects, but there are some.  Currently, we support
     26 Linux, Windows, Mac OS X, and Cygwin.  We will also make our best
     27 effort to support other platforms (e.g. Solaris, AIX, and z/OS).
     28 However, since core members of the Google Test project have no access
     29 to these platforms, Google Test may have outstanding issues there.  If
     30 you notice any problems on your platform, please notify
     31 googletestframework (a] googlegroups.com.  Patches for fixing them are
     32 even more welcome!
     33 
     34 ### Linux Requirements ###
     35 
     36 These are the base requirements to build and use Google Test from a source
     37 package (as described below):
     38   * GNU-compatible Make or gmake
     39   * POSIX-standard shell
     40   * POSIX(-2) Regular Expressions (regex.h)
     41   * A C++98-standard-compliant compiler
     42 
     43 ### Windows Requirements ###
     44 
     45   * Microsoft Visual C++ 7.1 or newer
     46 
     47 ### Cygwin Requirements ###
     48 
     49   * Cygwin 1.5.25-14 or newer
     50 
     51 ### Mac OS X Requirements ###
     52 
     53   * Mac OS X 10.4 Tiger or newer
     54   * Developer Tools Installed
     55 
     56 Also, you'll need CMake 2.6.4 or higher if you want to build the
     57 samples using the provided CMake script, regardless of the platform.
     58 
     59 Requirements for Contributors
     60 -----------------------------
     61 
     62 We welcome patches.  If you plan to contribute a patch, you need to
     63 build Google Test and its own tests from an SVN checkout (described
     64 below), which has further requirements:
     65 
     66   * Python version 2.3 or newer (for running some of the tests and
     67     re-generating certain source files from templates)
     68   * CMake 2.6.4 or newer
     69 
     70 Getting the Source
     71 ------------------
     72 
     73 There are two primary ways of getting Google Test's source code: you
     74 can download a stable source release in your preferred archive format,
     75 or directly check out the source from our Subversion (SVN) repositary.
     76 The SVN checkout requires a few extra steps and some extra software
     77 packages on your system, but lets you track the latest development and
     78 make patches much more easily, so we highly encourage it.
     79 
     80 ### Source Package ###
     81 
     82 Google Test is released in versioned source packages which can be
     83 downloaded from the download page [1].  Several different archive
     84 formats are provided, but the only difference is the tools used to
     85 manipulate them, and the size of the resulting file.  Download
     86 whichever you are most comfortable with.
     87 
     88   [1] http://code.google.com/p/googletest/downloads/list
     89 
     90 Once the package is downloaded, expand it using whichever tools you
     91 prefer for that type.  This will result in a new directory with the
     92 name "gtest-X.Y.Z" which contains all of the source code.  Here are
     93 some examples on Linux:
     94 
     95   tar -xvzf gtest-X.Y.Z.tar.gz
     96   tar -xvjf gtest-X.Y.Z.tar.bz2
     97   unzip gtest-X.Y.Z.zip
     98 
     99 ### SVN Checkout ###
    100 
    101 To check out the main branch (also known as the "trunk") of Google
    102 Test, run the following Subversion command:
    103 
    104   svn checkout http://googletest.googlecode.com/svn/trunk/ gtest-svn
    105 
    106 Setting up the Build
    107 --------------------
    108 
    109 To build Google Test and your tests that use it, you need to tell your
    110 build system where to find its headers and source files.  The exact
    111 way to do it depends on which build system you use, and is usually
    112 straightforward.
    113 
    114 ### Generic Build Instructions ###
    115 
    116 Suppose you put Google Test in directory ${GTEST_DIR}.  To build it,
    117 create a library build target (or a project as called by Visual Studio
    118 and Xcode) to compile
    119 
    120   ${GTEST_DIR}/src/gtest-all.cc
    121 
    122 with
    123 
    124   ${GTEST_DIR}/include and ${GTEST_DIR}
    125 
    126 in the header search path.  Assuming a Linux-like system and gcc,
    127 something like the following will do:
    128 
    129   g++ -I${GTEST_DIR}/include -I${GTEST_DIR} -c ${GTEST_DIR}/src/gtest-all.cc
    130   ar -rv libgtest.a gtest-all.o
    131 
    132 Next, you should compile your test source file with
    133 ${GTEST_DIR}/include in the header search path, and link it with gtest
    134 and any other necessary libraries:
    135 
    136   g++ -I${GTEST_DIR}/include path/to/your_test.cc libgtest.a -o your_test
    137 
    138 As an example, the make/ directory contains a Makefile that you can
    139 use to build Google Test on systems where GNU make is available
    140 (e.g. Linux, Mac OS X, and Cygwin).  It doesn't try to build Google
    141 Test's own tests.  Instead, it just builds the Google Test library and
    142 a sample test.  You can use it as a starting point for your own build
    143 script.
    144 
    145 If the default settings are correct for your environment, the
    146 following commands should succeed:
    147 
    148   cd ${GTEST_DIR}/make
    149   make
    150   ./sample1_unittest
    151 
    152 If you see errors, try to tweak the contents of make/Makefile to make
    153 them go away.  There are instructions in make/Makefile on how to do
    154 it.
    155 
    156 ### Using CMake ###
    157 
    158 Google Test comes with a CMake build script (CMakeLists.txt) that can
    159 be used on a wide range of platforms ("C" stands for cross-platofrm.).
    160 If you don't have CMake installed already, you can download it for
    161 free from http://www.cmake.org/.
    162 
    163 CMake works by generating native makefiles or build projects that can
    164 be used in the compiler environment of your choice.  The typical
    165 workflow starts with:
    166 
    167   mkdir mybuild       # Create a directory to hold the build output.
    168   cd mybuild
    169   cmake ${GTEST_DIR}  # Generate native build scripts.
    170 
    171 If you want to build Google Test's samples, you should replace the
    172 last command with
    173 
    174   cmake -Dgtest_build_samples=ON ${GTEST_DIR}
    175 
    176 If you are on a *nix system, you should now see a Makefile in the
    177 current directory.  Just type 'make' to build gtest.
    178 
    179 If you use Windows and have Vistual Studio installed, a gtest.sln file
    180 and several .vcproj files will be created.  You can then build them
    181 using Visual Studio.
    182 
    183 On Mac OS X with Xcode installed, a .xcodeproj file will be generated.
    184 
    185 ### Legacy Build Scripts ###
    186 
    187 Before settling on CMake, we have been providing hand-maintained build
    188 projects/scripts for Visual Studio, Xcode, and Autotools.  While we
    189 continue to provide them for convenience, they are not actively
    190 maintained any more.  We highly recommend that you follow the
    191 instructions in the previous two sections to integrate Google Test
    192 with your existing build system.
    193 
    194 If you still need to use the legacy build scripts, here's how:
    195 
    196 The msvc\ folder contains two solutions with Visual C++ projects.
    197 Open the gtest.sln or gtest-md.sln file using Visual Studio, and you
    198 are ready to build Google Test the same way you build any Visual
    199 Studio project.  Files that have names ending with -md use DLL
    200 versions of Microsoft runtime libraries (the /MD or the /MDd compiler
    201 option).  Files without that suffix use static versions of the runtime
    202 libraries (the /MT or the /MTd option).  Please note that one must use
    203 the same option to compile both gtest and the test code.  If you use
    204 Visual Studio 2005 or above, we recommend the -md version as /MD is
    205 the default for new projects in these versions of Visual Studio.
    206 
    207 On Mac OS X, open the gtest.xcodeproj in the xcode/ folder using
    208 Xcode.  Build the "gtest" target.  The universal binary framework will
    209 end up in your selected build directory (selected in the Xcode
    210 "Preferences..." -> "Building" pane and defaults to xcode/build).
    211 Alternatively, at the command line, enter:
    212 
    213   xcodebuild
    214 
    215 This will build the "Release" configuration of gtest.framework in your
    216 default build location.  See the "xcodebuild" man page for more
    217 information about building different configurations and building in
    218 different locations.
    219 
    220 Tweaking Google Test
    221 --------------------
    222 
    223 Google Test can be used in diverse environments.  The default
    224 configuration may not work (or may not work well) out of the box in
    225 some environments.  However, you can easily tweak Google Test by
    226 defining control macros on the compiler command line.  Generally,
    227 these macros are named like GTEST_XYZ and you define them to either 1
    228 or 0 to enable or disable a certain feature.
    229 
    230 We list the most frequently used macros below.  For a complete list,
    231 see file include/gtest/internal/gtest-port.h.
    232 
    233 ### Choosing a TR1 Tuple Library ###
    234 
    235 Some Google Test features require the C++ Technical Report 1 (TR1)
    236 tuple library, which is not yet available with all compilers.  The
    237 good news is that Google Test implements a subset of TR1 tuple that's
    238 enough for its own need, and will automatically use this when the
    239 compiler doesn't provide TR1 tuple.
    240 
    241 Usually you don't need to care about which tuple library Google Test
    242 uses.  However, if your project already uses TR1 tuple, you need to
    243 tell Google Test to use the same TR1 tuple library the rest of your
    244 project uses, or the two tuple implementations will clash.  To do
    245 that, add
    246 
    247   -DGTEST_USE_OWN_TR1_TUPLE=0
    248 
    249 to the compiler flags while compiling Google Test and your tests.  If
    250 you want to force Google Test to use its own tuple library, just add
    251 
    252   -DGTEST_USE_OWN_TR1_TUPLE=1
    253 
    254 to the compiler flags instead.
    255 
    256 If you don't want Google Test to use tuple at all, add
    257 
    258   -DGTEST_HAS_TR1_TUPLE=0
    259 
    260 and all features using tuple will be disabled.
    261 
    262 ### Multi-threaded Tests ###
    263 
    264 Google Test is thread-safe where the pthread library is available.
    265 After #include "gtest/gtest.h", you can check the GTEST_IS_THREADSAFE
    266 macro to see whether this is the case (yes if the macro is #defined to
    267 1, no if it's undefined.).
    268 
    269 If Google Test doesn't correctly detect whether pthread is available
    270 in your environment, you can force it with
    271 
    272   -DGTEST_HAS_PTHREAD=1
    273 
    274 or
    275 
    276   -DGTEST_HAS_PTHREAD=0
    277 
    278 When Google Test uses pthread, you may need to add flags to your
    279 compiler and/or linker to select the pthread library, or you'll get
    280 link errors.  If you use the CMake script or the deprecated Autotools
    281 script, this is taken care of for you.  If you use your own build
    282 script, you'll need to read your compiler and linker's manual to
    283 figure out what flags to add.
    284 
    285 ### As a Shared Library (DLL) ###
    286 
    287 Google Test is compact, so most users can build and link it as a
    288 static library for the simplicity.  You can choose to use Google Test
    289 as a shared library (known as a DLL on Windows) if you prefer.
    290 
    291 To compile *gtest* as a shared library, add
    292 
    293   -DGTEST_CREATE_SHARED_LIBRARY=1
    294 
    295 to the compiler flags.  You'll also need to tell the linker to produce
    296 a shared library instead - consult your linker's manual for how to do
    297 it.
    298 
    299 To compile your *tests* that use the gtest shared library, add
    300 
    301   -DGTEST_LINKED_AS_SHARED_LIBRARY=1
    302 
    303 to the compiler flags.
    304 
    305 Note: while the above steps aren't technically necessary today when
    306 using some compilers (e.g. GCC), they may become necessary in the
    307 future, if we decide to improve the speed of loading the library (see
    308 http://gcc.gnu.org/wiki/Visibility for details).  Therefore you are
    309 recommended to always add the above flags when using Google Test as a
    310 shared library.  Otherwise a future release of Google Test may break
    311 your build script.
    312 
    313 ### Avoiding Macro Name Clashes ###
    314 
    315 In C++, macros don't obey namespaces.  Therefore two libraries that
    316 both define a macro of the same name will clash if you #include both
    317 definitions.  In case a Google Test macro clashes with another
    318 library, you can force Google Test to rename its macro to avoid the
    319 conflict.
    320 
    321 Specifically, if both Google Test and some other code define macro
    322 FOO, you can add
    323 
    324   -DGTEST_DONT_DEFINE_FOO=1
    325 
    326 to the compiler flags to tell Google Test to change the macro's name
    327 from FOO to GTEST_FOO.  Currently FOO can be FAIL, SUCCEED, or TEST.
    328 For example, with -DGTEST_DONT_DEFINE_TEST=1, you'll need to write
    329 
    330   GTEST_TEST(SomeTest, DoesThis) { ... }
    331 
    332 instead of
    333 
    334   TEST(SomeTest, DoesThis) { ... }
    335 
    336 in order to define a test.
    337 
    338 Upgrating from an Earlier Version
    339 ---------------------------------
    340 
    341 We strive to keep Google Test releases backward compatible.
    342 Sometimes, though, we have to make some breaking changes for the
    343 users' long-term benefits.  This section describes what you'll need to
    344 do if you are upgrading from an earlier version of Google Test.
    345 
    346 ### Upgrading from 1.3.0 or Earlier ###
    347 
    348 You may need to explicitly enable or disable Google Test's own TR1
    349 tuple library.  See the instructions in section "Choosing a TR1 Tuple
    350 Library".
    351 
    352 ### Upgrading from 1.4.0 or Earlier ###
    353 
    354 The Autotools build script (configure + make) is no longer officially
    355 supportted.  You are encouraged to migrate to your own build system or
    356 use CMake.  If you still need to use Autotools, you can find
    357 instructions in the README file from Google Test 1.4.0.
    358 
    359 On platforms where the pthread library is available, Google Test uses
    360 it in order to be thread-safe.  See the "Multi-threaded Tests" section
    361 for what this means to your build script.
    362 
    363 If you use Microsoft Visual C++ 7.1 with exceptions disabled, Google
    364 Test will no longer compile.  This should affect very few people, as a
    365 large portion of STL (including <string>) doesn't compile in this mode
    366 anyway.  We decided to stop supporting it in order to greatly simplify
    367 Google Test's implementation.
    368 
    369 Developing Google Test
    370 ----------------------
    371 
    372 This section discusses how to make your own changes to Google Test.
    373 
    374 ### Testing Google Test Itself ###
    375 
    376 To make sure your changes work as intended and don't break existing
    377 functionality, you'll want to compile and run Google Test's own tests.
    378 For that you can use CMake:
    379 
    380   mkdir mybuild
    381   cd mybuild
    382   cmake -Dgtest_build_tests=ON ${GTEST_DIR}
    383 
    384 Make sure you have Python installed, as some of Google Test's tests
    385 are written in Python.  If the cmake command complains about not being
    386 able to find Python ("Could NOT find PythonInterp (missing:
    387 PYTHON_EXECUTABLE)"), try telling it explicitly where your Python
    388 executable can be found:
    389 
    390   cmake -DPYTHON_EXECUTABLE=path/to/python -Dgtest_build_tests=ON ${GTEST_DIR}
    391 
    392 Next, you can build Google Test and all of its own tests.  On *nix,
    393 this is usually done by 'make'.  To run the tests, do
    394 
    395   make test
    396 
    397 All tests should pass.
    398 
    399 ### Regenerating Source Files ###
    400 
    401 Some of Google Test's source files are generated from templates (not
    402 in the C++ sense) using a script.  A template file is named FOO.pump,
    403 where FOO is the name of the file it will generate.  For example, the
    404 file include/gtest/internal/gtest-type-util.h.pump is used to generate
    405 gtest-type-util.h in the same directory.
    406 
    407 Normally you don't need to worry about regenerating the source files,
    408 unless you need to modify them.  In that case, you should modify the
    409 corresponding .pump files instead and run the pump.py Python script to
    410 regenerate them.  You can find pump.py in the scripts/ directory.
    411 Read the Pump manual [2] for how to use it.

    415 ### Contributing a Patch ###
    416 
    417 We welcome patches.  Please read the Google Test developer's guide [3]
    418 for how you can contribute.  In particular, make sure you have signed
    419 the Contributor License Agreement, or we won't be able to accept the
    420 patch.
