PexLogo Pex (from the Microsoft Research Lab) has finally been released the public. Pex 0.5 can be downloaded here.

What is Pex?


“Pex (Program EXploration) is a white-box test generation tool. Given a hand-written parameterized unit test, Pex analyzes the code to determine relevant test inputs fully automatically. The result is a traditional unit test suite with high code coverage. In addition, Pex suggests to the programmer how to fix bugs.”


I haven’t had a chance to dive in but I’m pretty excited to see how this can speed up production of writing white box tests and/or increase the code coverage on QA’s side.


At the end of the day it’d be nice to see this in the developers’ hands and not mine. Baby steps though…
