Tests with CUNIT - walkthrough analysis / code coverage

Question

I want to test some code with CUnit. Does anyone know if it is possible to do a walktrough Analysis?

I want to have something, that says, you`ve tested 80% of your function.

It must be ensured, that 100% coverage are reached with the test.

Answer 1

There are a few tools that will help - the basic free one is gcov, which will do what you need but will involve a certain amount of setup, etc.

There are other (commercial) ones, but what's available changes, including if there are non-commercial free/low-cost licences. Having said that, http://c2.com/cgi/wiki?CodeCoverageTools might be worth a starting point if you need more than gcov.
