Zooming into "requirements management" (and out of "developing test cases") there's a couple of Open Source projects that address specifically this important branch of software development. I like both approaches and I think they might be used in different situations. By the way, the creators of these two projects are having useful conversations on aspects of their solutions so you might want to try both and see what's leading from your point of view.

Of course requirements can be linked to test cases and test execution reports, based on a defined and described process.

How to build test cases is another story.
