JUnit 4.7 introduced the concept of custom rules:

http://www.infoq.com/news/2009/07/junit-4.7-rules

There are a number of built in JUnit rules including TemporaryFolder which helps by clearing up folders after a test has been run:

@Rule
public TemporaryFolder tempFolder = new TemporaryFolder();

There's a full list of built in rules here:

I'm interested in finding out what custom rules are in place where you work or what useful custom rules you currently use?
