Looks like there is a typo in the docs.  It should be

Yes, the docs are wrong here too and I can't get that option working 
either.  I'll get back to you when I have more info on this part of the

Hmm, well, it took me quite a while of digging through source code to 
figure out how to get this to work at all and here is one example that 
does work, although without the --one-module-per-process option:

   python ~/src/ide/src/testing/runners/run_unittests_xml.py 
--output-file=test.xml -q test_textutils.CTextUtils.testQuotedSplit

The key things are the -q option followed by 
modulename.classname.testName (not just testName by itself).

Sorry this is so poorly documented.  I'll fix the docs and will get back 
to you when we have a fix for the --one-module-per-process option.

Thanks for pointing out these problems!
