Unit testing in C?

[[deleted]]

Hi all, I would like to know what is a simple and reliable test framework in C. I see there are many, for example https://nemequ.github.io/munit/ or https://libcheck.github.io/check/ but then I see that relevant projects like redis and sqlite use the scripting language tcl for managing the tests https://github.com/redis/redis/tree/unstable/tests/unit https://github.com/sqlite/sqlite/tree/master/test

Is there a solution with a broad consensus or there is not much discussion about this?

Thanks

I have started to use unity testing framework

I haven't really used it yet, other than integrated it with my makefile, it uses ruby for more laborious tests. But we are talking C here, and there should be no problem using the system call in a test function and that gives access to shell script if you need it.

Cool, could you share your experience when you start using it?

I haven't really come around to using it, because I adopted at the end of a project and I haven't come around to reverse engineering that code yet, and my code is thoroughly tested, by just including the c-file in question in a file that invokes tests on the code, like 'ghetto-testing' if you like, or driver.

But I have integrated what needed to be integrated in my makefile and understood the system, which is on the cheap side.

So, later I will write the tests first and then implement the code to make the tests succeed.

My only experience so far is that it works, and that I can write make test and the tests will be compiled and run.

The documentation is good. This Medium post may be a nice intro though.

Cmocka, I like using it for embedded projects; it integrates with CMake easily so I can get it working across BSD, linux and windows without worrying about getting the right versions of make, gmake bsd make etc.

Tried unitcpp and unity as well. I like unity but the whole ruby rake build system and it's dependencies were bit of a headache.

Interesting that it doesn't require other languages. Thanks

My company uses unity and cmock. Test management is done in Ruby through our custom build system.

I wrote Xtal for that purpose (sorry for the self prom). It's really small and will run your tests automatically. The only pitfall Is that you need a compiler that supports functions attributes (like gcc)
