Miachel Kolt has a nice short piece on leveraging the VSTS IDE to handle method creation for you as you do Test Driven Development.

I had spent some time with the ThoughtWorks guys here in Chicago and was totally sold on TDD, but doing so with Visual Studio 2003 was cumbersome at best.

IntelliJ IDEA has a rockin' Java IDE with the best refactoring and TDD support I've seen (unfortuantely, not enough dev's out there use IDEA, instead using the tools provided by their J2EE vendors or Eclipse [sometimes one in the same])
