[FIXED] How to set up a unit-tested C project in Eclipse

Issue

I'm sure this is documented somewhere but I'm struggling to find what I'm after. I am developing a project in C (and explicitly not C++), and having had good experiences developing Java projects with JUnit for TDD, I'd like to take a similar approach for this new project.

Can anyone provide a walkthrough for creating and running a simple C project, and running a couple of unit tests on them within Eclipse CDT? I have Eclipse CDT (Luna) and the unit-testing plugin as described in the frequently referenced blog. Most of the guidance appears to be for C++.

FWIW I'm running on Windows 7 and compiling with MinGW GCC.

Solution

Have you given google test a try? Its technically a c++ library, but has very little overhead to test your functions. A c++ test project would easily be able to consume the library generated from your c code, so should be pretty easy.

For example, this is what a test would look like

#include "gtest/gtest.h"
#include "MyProject/myFunc.h

TEST (myFuncTest, calculate) { 
    EXPECT_EQ (18.0, myFunc_calculate (324.0));
}

You can find more details at IBM Developerworks on YouTube etc.
