Units is simple / dynamic unit testing framework for C (and C++, I suppose).
- Tests are sandboxed, but can share functions in their own files
- There is no global configuration. All tests are completely contained within their own file, no registration needed.
- It should run on any unix system with a somewhat recent version of GCC (tested on 4.2 and 4.6)
- Output is TAP compliant
###Writing tests See example.c. Each function is called individually as its own test if included with add_test. Tests are sandboxed in child processes so there is no memory sharing between them.
###Running tests Running tests is easy. For most projects you can simply drop a .c in the tests directory, build and run:
user@host:~/code/units$ make compiling main.c compiling tests/example.c linking runtests user@host:~/code/units$ ./runtests 1..4 ok 1 - always_passing not ok 2 - always_failing not ok 3 - fail_with_output this is a string with linebreaks in the failure output ok 4 - pass_with_output everything went better than expected # 4 tests run, 2/4 passed
