CMock is a mock and stub generator and runtime for unit testing C. It's been designed to work smoothly with Unity Test, another of the embedded-software testing tools developed by ThrowTheSwitch.org. CMock automagically parses your C headers and creates useful and usable mock interfaces for unit testing. Give it a try!
If you don't care to manage unit testing builds yourself, consider checking out Ceedling, a test-centered build manager for unit testing C code.
Your first step is to get yourself a copy of CMock. There are a number of ways to do this:
-
If you're using Ceedling, there is no need to install CMock. It will handle it for you.
-
The simplest way is to grab it off github. The Github method looks something like this:
git clone --recursive https://github.com/throwtheswitch/cmock.git
-
You can also grab the
zipfile from github. If you do this, you'll also need to grab yourself a copy of Unity and CException, because github unfortunately doesn't bake dependencies into the zip files.
If you plan to help with the development of CMock (or just want to verify that it can perform its self tests on your system) then you can grab its self-testing dependencies, then run its self-tests:
> cd cmock
> bundle install # Ensures you have all RubyGems needed
> cd test
> rake # Run all CMock self tests
