Minunit - slightly extended
This is a slightly extended version of minunit C unit test "framework". This version of the framework has been designed for performing coding Dojos, and is not production-ready (assuming that you'd want to use minunit for unit testing your production code)
Minunit is a minimalist C unit testing framework. While minified to its simplest expression (only 2 macros) it does the job pretty well, and it has the advantage that one can completely understand what it does.
Originally a fork from ValiValpas, ValiValpas macros did not work while using GCC on the Raspberry Pi (and was generating core when compiled on Cygwin's GCC), therefore I entirely revised the extended version of this framework: back to basics with minor improvements.
I strongly advise to look at JTN002, that introduced and explains the minunit framework.
This fork has been created, reworked and used at the ISE LAB #06, featuring a TDD coding dojo in C on Raspberry Pi.
Modifications to minunit
More meaningful test failure messages, it now indicates what was the file on which the test failed and the line.
Utility script
The script is a simple (and stupid) shell script that assumes that:
- Your module is composed of
<module>.cand<module>.h - Your test suite is names
<module>_suite.c - You are using gcc (you should better replace by $CC)
It does the following (based on assumptions explained above):
- Find existing test suites
- Compile them
- Run them
How I use it
I run the unit tests in background, for example every 5 seconds (for a small dojo with quick feedback). So I simply run the following command line: watch --interval=5 ./run_tests.sh
Then code and see how the test pass by the same time.
