[TIP] Need help with IsolationPlugin and nose 0.10 API

[Kumar McMillan]

Hi Brandon.
from your Active State comment
http://community.activestate.com/impatient-developers-guide-writing-python-nose-plugins#comment-4864
it looks like what you are actually trying to do is re-run your suite
after the code has changed, correct?

The isolation plugin is kind of overkill for this because it uses a
separate process for *each* test, thus slowing down the test suite
considerably.  Another approach might be to drive a nosetests
subprocess that calls nose.run() and exits [1].  This would mean you'd
have to scrape the output but you'd probably have to do that anyway
unless you are introspecting the unittest TestResult (which would be
painful).  Alternatively, you could submit a feature request asking
for a way to "clear" all test suites from memory:
http://code.google.com/p/python-nose/issues/list
...this shouldn't be too hard (famous last words:)).

[1] I did this once and it worked just fine:
