Unit testing with JUnit is a powerful way to ensure the integrity of your code base, but some invariants are more difficult to test than others (which is one of the method call sequences). In the part of diagnosing Java code, Eric Allen describes how to use a logger (a special listener) in your unit tests to ensure that a method call sequence occurs in the proper order.
