Is there a unit testing framework for testing PowerShell with PowerShell scripts?

Question

I am lookin for a unit testing framework of type xUnit that lets me test PowerShell functions with PowerShell scripts.

Answer 1

While not an actual framework a la xUnit, Lee Holmes did write an article about how to unit test PowerShell using PowerShell scripts.

Answer 2

Well, just for completeness: There is actually PSUnit. Doesn't seem to be very mature, though as I see only two spikes of activity since its beginning as well as no documentation to speak of.

But as I learnt from cuTest, unit testing is something that fits into a very small space (at least for C in that case), so having something that works might not require too much effort.

Answer 3

I also found PSUnit on Codeplex. PSUnit PowerShell Unit Testing Framework

There are some cool screen shots and a release is expected in August this year.
