(tried sending this earlier but I think I got bit by the DNS issue) Mark Hindess of the Harmony project has written an interesting little test tool that I thought you guys might be interested in. I haven't time to look at it very closely myself, but the concept seems sound. As I understand it what he does is take a japi file and generate tests which call constructors and static methods with various combinations of probably-invalid arguments, such as empty strings and nulls. For each one it then records the exception thrown if any by the implementation for comparison with other implementations. It seems like a good way to catch corner-case differences which are unlikely to be caught any other way - until some application gets an exception different than the one it was expecting and falls over. His script is available here: http://issues.apache.org/jira/browse/HARMONY-325 Thoughts? Feelings? Stuart. -- http://sab39.dev.netreach.com/
