Test framework of choice?

[Mitchell Morris]

In the course of finding a reasonably standard-ish test framework, I found 
a curiousity: <URL:http://www.xprogramming.com/software.htm> reports three 
separate implementations for Python. It appears from my cursory reading 
that either Bob Martin's OmPyUnit or Stephen Purcell's pyunit would be the 
preferred mechanism, but I can't be sure. My kneejerk reaction is to use 
pyunit merely because it's hosted at SourceForge, but I'm not at all sure 
that software should be blessed merely because of who hosts the CVS tree.

Is there any consensus, emerging or otherwise, as to which is more likely 
to survive any putative consolidation efforts? Is either of them going to 
be included in the core Python distribution? Are there any plans to include 
any kind of regression testing framework into the standard distribution?
