# Google Test #
Welcome to **Google Test**, Google's C++ test framework!
This GitHub repository is a merger of the formerly separate GoogleTest and GoogleMock projects.
These were so closely related that it makes sense to maintain and release them together.

## About Google Mock ##
## Requirements ##
**Google Mock** is an extension to Google Test for writing and using C++ mock classes.
It is inspired by [jMock](http://www.jmock.org/), [EasyMock](http://www.easymock.org/),
and [Hamcrest](http://code.google.com/p/hamcrest/), and designed with C++'s specifics in mind.
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
<googletestframework@googlegroups.com>. Patches for fixing them are
even more welcome!
Google mock:
### Linux Requirements ###
* lets you create mock classes trivially using simple macros.
* supports a rich set of matchers and actions.
* handles unordered, partially ordered, or completely ordered expectations.
* is extensible by users.
These are the base requirements to build and use Google Test from a source
package (as described below):
We hope you find it useful!
* GNU-compatible Make or gmake
* POSIX-standard shell
* POSIX(-2) Regular Expressions (regex.h)
* A C++98-standard-compliant compiler
## Using Google Mock Without Google Test ##
Google Mock is not a testing framework itself. Instead, it needs a
testing framework for writing tests. Google Mock works seamlessly
with [Google Test](http://code.google.com/p/googletest/), butj
you can also use it with [any C++ testing framework](googlemock/ForDummies.md#Using_Google_Mock_with_Any_Testing_Framework).
### Windows Requirements ###
## Getting Started ##
* Microsoft Visual C++ v7.1 or newer
If you are new to the project, we suggest that you read the user
documentation in the following order:
### Cygwin Requirements ###
* Learn the [basics](http://code.google.com/p/googletest/wiki/Primer) of Google Test, if you choose to use Google Mock with it (recommended).
* Read [Google Mock for Dummies](ForDummies.md).
* Read the instructions on how to [build Google Mock](http://code.google.com/p/googlemock/source/browse/trunk/README).
* Cygwin v1.5.25-14 or newer
You can also watch Zhanyong's [talk](http://www.youtube.com/watch?v=sYpCyLI47rM) on Google Mock's usage and implementation.
### Mac OS X Requirements ###
Once you understand the basics, check out the rest of the docs:
* Mac OS X v10.4 Tiger or newer
* XCode Developer Tools
* [CheatSheet](googlemock/docs/CheatSheet.md) - all the commonly used stuff at a glance.
* [CookBook](googlemock/docs/CookBook.md) - recipes for getting things done, including advanced techniques.
Also, you'll need [CMake](http://www.cmake.org/) v2.6.4 or higher if
you want to build the samples using the provided CMake script, regardless
of the platform.
If you need help, please check the [KnownIssues](googlemock/docs/KnownIssues.md) and
[FrequentlyAskedQuestions](googlemock/docs/frequentlyaskedquestions.md) before
posting a question on the [googlemock discussion group](http://groups.google.com/group/googlemock).
### Requirements for Contributors ###
We'd love to have your help! Please read the Developer Guides if you are willing to contribute to the development.
We welcome patches. If you plan to contribute a patch, you need to
build Google Test and its own tests from a git checkout (described
below), which has further requirements:
Happy mocking!
* [Python](http://python.org/) v2.3 or newer (for running some of
the tests and re-generating certain source files from templates)
* [CMake](http://www.cmake.org/) v2.6.4 or newer
## Regenerating Source Files ##
Some of Google Test's source files are generated from templates (not
in the C++ sense) using a script.
For example, the
file include/gtest/internal/gtest-type-util.h.pump is used to generate
gtest-type-util.h in the same directory.
You don't need to worry about regenerating the source files
unless you need to modify them. You would then modify the
corresponding `.pump` files and run the '[pump.py](googletest/scripts/pump.py)'
generator script. See the [Pump Manual](googletest/docs/PumpManual.md).
### Contributing Code ###
We welcome patches. Please read the
[Developer's Guide](googletest/docs/DevGuide.md)
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.
Happy testing!

Google Mock:
It is inspired by:
- provides a declarative syntax for defining mocks,
- can easily define partial (hybrid) mocks, which are a cross of real
and mock objects,
- handles functions of arbitrary types and overloaded functions,
- comes with a rich set of matchers for validating function arguments,
- uses an intuitive syntax for controlling the behavior of a mock,
- does automatic verification of expectations (no record-and-replay
needed),
- allows arbitrary (partial) ordering constraints on
function calls to be expressed,
- lets a user extend it by defining new matchers and actions.
- does not use exceptions, and
- is easy to learn and use.

## Getting Started ##
Google Mock is implemented on top of the [Google Test C++ testing
framework](http://github.com/google/googletest/), and depends on it.
You must use the bundled version of Google Test when using Google Mock, or
you may get compiler/linker errors.
If you are new to the project, we suggest that you read the user
documentation in the following order:
* Learn the [basics](../googletest/docs/Primer.md) of
Google Test, if you choose to use Google Mock with it (recommended).
* Read [Google Mock for Dummies](docs/ForDummies.md).
* Read the instructions below on how to build Google Mock.

Getting the Source
------------------
### Building Google Mock ###
There are two primary ways of getting Google Mock's source code: you
can download a [stable source release](releases),
or directly check out the source from our Git repository.
The Git checkout requires a few extra steps and some extra software
packages on your system, but lets you track development and make
patches much more easily, so we highly encourage it.
#### Preparing to Build (Unix only) ####
### Git Checkout ###
To check out the master branch of Google Mock, run the following git command:
git clone https://github.com/google/googlemock.git
If you are using a \*nix system and plan to use the GNU Autotools build
If you are using a Unix system and plan to use the GNU Autotools build

configure it now.
To prepare the Autotools build system, enter the target directory of
the checkout command you used ('gmock-svn') and proceed with the
following command:
To prepare the Autotools build system:
cd googlemock
autoreconf -fvi
Once you have completed this step, you are ready to build the library.
Note that you should only need to complete this step once. The
subsequent 'make' invocations will automatically re-generate the bits
of the build system that need to be changed.
If your system uses older versions of the autotools, the above command
will fail. You may need to explicitly specify a version to use. For
instance, if you have both GNU Automake 1.4 and 1.9 installed and
'automake' would invoke the 1.4, use instead:
AUTOMAKE=automake-1.9 ACLOCAL=aclocal-1.9 autoreconf -fvi
Make sure you're using the same version of automake and aclocal.
Setting up the Build
--------------------
To build Google Mock 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.

### 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.
