The problem is that __main__ is not really the same when you run within
the Wing debugger, because the wrapper call wingdb.py is __main__.  We try
to hide this from the debug process but you've uncovered a bug in Wing
1.1b7-2 and earlier where our import hook is not returning the faked
__main__ upon __import__('__main__') (which is what unittest.py is doing).

There are two ways to work around this for now:

1) Write a small substitute main entry point for your test instead of
   using the "if __name__ == '__main__'" clause.  So in a seperate file
   you would have:

   import unittest
   unittest.main('mytestclasses')

   or:

   import unittest
   import mytestclasses
   unittest.main(mytestclasses)

   In this case you are explicitely giving the test modules so you
   don't run into the __main__ problem.

2) Use wingdbstub and launch the process from the command line.
   In this case __main__ is correct because there is no difference
   in what you're launching from the non-debug case.

The __import__('__main__') bug should be fixed in the next release.

Thanks for reporting this!
