Test planning/documentation/management tools

Question

I\'m looking for a good, preferably free, test planning and documentation tool. Ideally something that will keep track of which tests have been run against which software versio

Answer 1

I've heard good things about Fitnesse but I don't know how good it's test tracking is.

I know I just recently saw a slick looking test tracker for Trac or something, but I can't find it now...
