The eclipse plugins are:
- Jupiter, which organises all the reporting and tracking of defects. It incorporates a good review process.
- FindBugs, which uses byte code analysis to notice strange things about the code - and could quite possibly be sufficient for reviewing unit test classes on its own. See this paper for more information.
- JDocs, to help you look up the API information you need.
- CheckStyle, with all the class design and metrics analysis extras turned on. Use the metrics to target your second glances.
- and Dupman will analyse for duplicates, if you are brave enough to tackle the German documentation.
There are a number of other tools that can help, but these cover the same areas as CheckStyle and Dupman do together, so rather than put in a large number of specialised tools you can get away with using the extras of the latest version of checkstyle and a good (free) duplication spotter.
FindBugs is a fantastic concept, it is really a time saver in this case. It finds "problem areas" more than anything else and so does require someone afterwards to look at the code and say something like "hmmm... that could have been embarassing" or "its not actually wrong, but it needs refactoring anyway".
