I love CIJ. When I use git, I find myself making a lot of commits, and I want to see my test coverage aggregated by the jira ticket I've put in my commit log. For example, let's say I'm working on a project for 3 days. I might make 50 commits. All throughout my development, I'd like to keep a running track of how the test coverage is for my code, bounded by a commit regex. In other words, I'd like to use something like git blame, married with coverage, to give me feedback like "Hey Zim, the feature you're working on only has 52% coverage". Awesome-er still would be something like the class coverage pane, but using only lines I've changed. So I could have a window that shows the classes I've changed, and a summary of the coverage for the lines that I've changed, again bounded by a the jira ticket in my commit logs.

This would be crazy to do in something other than a lightning fast DVCS like git or mercurial...but I have totally drunk the git cool aid.
