Re: [Pyunit-interest] Help!

Hi Peter,

The function 'unittest.main()' is the top-level function that turns a  
python file into a standalone runnable test program.  It uses sys.exit 
() to indicate whether the tests passed or not.

What you see here is the result of running that function inside an  
interactive interpreter, which is intercepting the 'SystemExit' that  
is thrown by sys.exit().  If you don't care about the exit code, you  
can just wrap 'unittest.main()' in a try: except SystemExit: block.

Hope that helps,

-Steve
