JUnitMax beta is worth the price
Kent Beck has released JUnitMax for Eclipse as paid beta – currently USD $2/month. JUnitMax is a selective testing tool – it chooses a subset of tests to run so you get feedback very fast. I especially like the fact that the results are written into the same window as compiler failures. Think of JUnitMax as the twin sister of the incremental compiler.
I’ve tested it with the latest version of Apache Commons Collections and it works quite well. Of course its usefulness depends on whether you have fast and reliable tests in the first place, but if your project can benefit from fast tests – you have one less excuse not to write them.
