Unit testing for C?

9 points by dasmithii 12y ago ↗ HN

Being new to C in general, I haven't yet had to deal with large project structures. However, that's about to change. What would you recommend as a somewhat robust testing framework?

I'm not too picky, just looking for some reviews/experiences/hints. Thanks!

The last time I wrote a C project I used "cunit":

http://cunit.sourceforge.net/

It was nice that I could both compile the test-cases as standalone executables, and also build them into my main application. Running "./foo --tests" to run the test-suite post-installation was very nice for getting user-feedback.

There are a few frameworks for test-suites for C, and I looked around a fair bit before picking this one. Whether it suits you is an open question, but if you're not sold on it feel free to browse:

I found this presentation on test-driven development in C using assert and stdbool interesting:

It shows that you can accomplish quite a lot without a standalone testing framework. Good luck with writing C!

libcheck is nice

it forks off every test so its fast and failures like segfaults are really just test failures.
