Tool for testing using parameter permutations

Question

I remember there existed a testing program/library that will run your code and/or unit tests, creating all kinds of permutations of the parameters (null values, random integers, strings and so on). I just can't remember what it was called and searching google doesn't seem to come up with anything.

I know it was created for Java code and I think it was quite expensive as well. That's really all I can remember, anyone have a clue what program/library I am thinking about?

Answer 1

The AgitarOne JUnit Generator comes to mind. I'm not sure it's what you're thinking of, though.

Answer 2

JTest from Parasoft may be what you're thinking of.
