Is this about the sad state of test frameworks or about the sad state of C test frameworks? There's a reference to JUnit I don't understand. Junit provides the ability to aggregate tests in suites (strict hierarchies wtf?).

Benchmark may be a different concern.. I know you can do something with rules but it may require more time to set up.

By the way: creating a small, self developed tool that just does what you need is sometimes a good idea, but it doesn't mean everything else is shit. Any library serving a large user base will serve somebody better than others.
