## Google Mock ##
|

# Googletest Mocking (gMock) Framework
|
||||
|
||||
The Google C++ mocking framework.
|
||||
### Overview
|

|

Google's framework for writing and using C++ mock classes.

It can help you derive better designs of your system and write better tests.
|
||||
Google's framework for writing and using C++ mock classes. It can help you
|
||||
derive better designs of your system and write better tests.
|
||||
|
||||
It is inspired by:
|
||||
|
||||
* [jMock](http://www.jmock.org/),
|
||||
* [EasyMock](http://www.easymock.org/), and
|
||||
* [Hamcrest](http://code.google.com/p/hamcrest/),
|
||||
* [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 mock:
|
||||
gMock:
|
||||
|
||||
* 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.
|
||||
- provides a declarative syntax for defining mocks,
|
||||
- can 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.
|
||||
|
||||
We hope you find it useful!

|

|
||||
## Getting Started ##
|
||||
|
||||
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](../googlemock/docs/for_dummies.md).
|
||||
* Read the instructions below on how to build Google Mock.
|
||||
|
||||
You can also watch Zhanyong's [talk](http://www.youtube.com/watch?v=sYpCyLI47rM) on Google Mock's usage and implementation.
|
||||
|
||||
Once you understand the basics, check out the rest of the docs:
|
||||
|
||||
* [CheatSheet](../googlemock/docs/cheat_sheet.md) - all the commonly used stuff
|
||||
at a glance.
|
||||
* [CookBook](../googlemock/docs/cook_book.md) - recipes for getting things done,
|
||||
including advanced techniques.
|
||||
|
||||
If you need help, please check the
|
||||
[KnownIssues](docs/known_issues.md) and
|
||||
[FrequentlyAskedQuestions](docs/frequently_asked_questions.md) before
|
||||
posting a question on the
|
||||
[discussion group](http://groups.google.com/group/googlemock).
|
||||
|
||||
|
||||
### 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](https://github.com/google/googletest), but
|
||||
you can also use it with [any C++ testing framework](../googlemock/docs/for_dummies.md#using-google-mock-with-any-testing-framework).
|
||||
|
||||
### Requirements for End Users ###
|
||||
|
||||
Google Mock is implemented on top of [Google Test](
|
||||
http://github.com/google/googletest/), and depends on it.
|
||||
You must use the bundled version of Google Test when using Google Mock.
|
||||
|
||||
You can also easily configure Google Mock to work with another testing
|
||||
framework, although it will still need Google Test. Please read
|
||||
["Using_Google_Mock_with_Any_Testing_Framework"](
|
||||
../googlemock/docs/for_dummies.md#using-google-mock-with-any-testing-framework)
|
||||
for instructions.
|
||||
|
||||
Google Mock depends on advanced C++ features and thus requires a more
|
||||
modern compiler. The following are needed to use Google Mock:
|
||||
|
||||
#### Linux Requirements ####
|
||||
|
||||
* GNU-compatible Make or "gmake"
|
||||
* POSIX-standard shell
|
||||
* POSIX(-2) Regular Expressions (regex.h)
|
||||
* C++98-standard-compliant compiler (e.g. GCC 3.4 or newer)
|
||||
|
||||
#### Windows Requirements ####
|
||||
|
||||
* Microsoft Visual C++ 8.0 SP1 or newer
|
||||
|
||||
#### Mac OS X Requirements ####
|
||||
|
||||
* Mac OS X 10.4 Tiger or newer
|
||||
* Developer Tools Installed
|
||||
|
||||
### Requirements for Contributors ###
|
||||
|
||||
We welcome patches. If you plan to contribute a patch, you need to
|
||||
build Google Mock and its tests, which has further requirements:
|
||||
|
||||
* Automake version 1.9 or newer
|
||||
* Autoconf version 2.59 or newer
|
||||
* Libtool / Libtoolize
|
||||
* Python version 2.3 or newer (for running some of the tests and
|
||||
re-generating certain source files from templates)
|
||||
|
||||
### Building Google Mock ###
|
||||
|
||||
#### Using CMake ####
|
||||
|
||||
If you have CMake available, it is recommended that you follow the
|
||||
[build instructions][gtest_cmakebuild]
|
||||
as described for Google Test.
|
||||
|
||||
If are using Google Mock with an
|
||||
existing CMake project, the section
|
||||
[Incorporating Into An Existing CMake Project][gtest_incorpcmake]
|
||||
may be of particular interest.
|
||||
To make it work for Google Mock you will need to change
|
||||
|
||||
target_link_libraries(example gtest_main)
|
||||
|
||||
to
|
||||
|
||||
target_link_libraries(example gmock_main)
|
||||
|
||||
This works because `gmock_main` library is compiled with Google Test.
|
||||
|
||||
|
||||
### Tweaking Google Mock ###
|
||||
|
||||
Google Mock 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 Mock 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 [${GTEST\_DIR}/include/gtest/internal/gtest-port.h](
|
||||
../googletest/include/gtest/internal/gtest-port.h).
|
||||
|
||||
### As a Shared Library (DLL) ###
|
||||
|
||||
Google Mock is compact, so most users can build and link it as a static
|
||||
library for the simplicity. Google Mock can be used as a DLL, but the
|
||||
same DLL must contain Google Test as well. See
|
||||
[Google Test's README][gtest_readme]
|
||||
for instructions on how to set up necessary compiler settings.
|
||||
|
||||
### Tweaking Google Mock ###
|
||||
|
||||
Most of Google Test's control macros apply to Google Mock as well.
|
||||
Please see [Google Test's README][gtest_readme] for how to tweak them.
|
||||
|
||||
### Upgrading from an Earlier Version ###
|
||||
|
||||
We strive to keep Google Mock 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 Mock.
|
||||
|
||||
#### Upgrading from 1.1.0 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](#choosing-a-tr1-tuple-library)".
|
||||
|
||||
#### Upgrading from 1.4.0 or Earlier ####
|
||||
|
||||
On platforms where the pthread library is available, Google Test and
|
||||
Google Mock use it in order to be thread-safe. For this to work, you
|
||||
may need to tweak your compiler and/or linker flags. Please see the
|
||||
"[Multi-threaded Tests](../googletest/README.md#multi-threaded-tests)" section in file Google Test's README for what you may need to do.
|
||||
|
||||
If you have custom matchers defined using `MatcherInterface` or
|
||||
`MakePolymorphicMatcher()`, you'll need to update their definitions to
|
||||
use the new matcher API (
|
||||
[monomorphic](./docs/cook_book.md#writing-new-monomorphic-matchers),
|
||||
[polymorphic](./docs/cook_book.md#writing-new-polymorphic-matchers)).
|
||||
Matchers defined using `MATCHER()` or `MATCHER_P*()` aren't affected.
|
||||
|
||||
Happy testing!

**Tip 2:** If your mock objects are never deleted, the final verification won't
|
||||
happen. Therefore it's a good idea to turn on the heap checker in your tests
|
||||
when you allocate mocks on the heap. You get that automatically if you use the
|
||||
`gunit_main` library already.
|
||||
`gtest_main` library already.

|

functions are called, otherwise the behavior is **undefined**. In particular,
