Re: Tool to create assertions from a running Java application

Maybe you can check out agitar. They provide a system that does exactly
this: Generate tests for existing code.
They made a big buzz a few years ago. I look into it very briefly and the
generated tests where not that bad.
The biggest problem was: They were far too numerous and too detailed.
Writing good tests puts emphasis on the important parts that really needs
to be tested and ignores exidential details.

I never quite understood how a tool like that should be used.

I know that Kent Beck was involved into the undertaking, but I think he is
no longer. Probably because it didn't quite work out in practice.
