IBM AlphaWorks has posted an preview of the Web Tools for Eclipse here. It says the final version will be out July 2005. I’m not really sure how old this preview is, but the date on the article says 10th of February. I’ll have to check it out one day.
Surrogate is an open source project for mocking dependencies in unit tests. It enables you to unit test existing code, without modification even though it is not based on dependency injection. It does this through AspectJ weaving where it intercepts calls to objects that needs to be mocked. Take a look at it, it should solve some hard to solve test cases you might run into (like simulating slow performance by replacing calls to System.currentTimeMillis()).
According to java.no it has been developed by Telenor (Norways largest telecom company), and according to their own docs used in large projects with 4000 unit tests.
Jetbrains is handing out licences to IntelliJ IDEA to open sourc projects. The requrements are quite fuzzy though, and I bet many sourceforge projects with 2-3 developers will have trouble passing. Or maybe they are just nice guys. 🙂 Read here.
