In WTP Source Editing we spend time, when we find it, bolstering our compatibility with the W3C DOM unit test suite (bug 214439).  Currently we fail nearly 100 of the 499 tests, and I find it difficult making forward progress as it is easy to make changes that (hypothetically) let us pass 5 tests while causing 4 tests that *used* to pass to now fail.  The overall numbers are better but it's basically a regression at that point, and one that's hard to figure out unless there's a way for me to compare the results of the suite executions before and after my changes (not comparing the results in a single execution as is offered for expected/actual).

Ideally when I bring up the History of runs, there'd be a new button to compare the exactly two runs I've selected so I can know both the net pass/fail change as well as easily spot tests that previously passed but now fail, and vice-versa.
