Q:

Ruby Test Coverage Mapping Tool

I want to map a large number of tests (rspec, test-unit, cucumber, selenium, etc.) over a very large (RoR) code base and look for intersections and overlaps in an attempt to reduce the number of tests being run, while maintaining code coverage. I have looked at SimpleCov (per: Ruby test coverage tool) and it's not quite extensive enough. 
An aside, a colleague mentioned a Hudson plugin that might be what I'm looking for, but couldn't remember it's name and some basic searches didn't yield any useful results.
Thanks!

A:

It seems the primary answer is, there isn't really anything out there, at least, not that I could find. However, that said, for most apps and in most cases, SimpleCov is what people are looking for.
