Unit Testing C Code [closed]

manpreet Best Answer 2 years ago

I worked on an embedded system this summer written in straight C. It was an existing project that the company I work for had taken over. I have become quite accustomed to writing unit tests in Java using JUnit but was at a loss as to the best way to write unit tests for existing code (which needed refactoring) as well as new code added to the system.

Is there any way to make unit testing plain C code as easy as unit testing Java code with, for example, JUnit? Any insight that would apply specifically to embedded development (cross-compiling to arm-linux platform) would be greatly appreciated.
