[IronPython] Prevention of SystemExit Dialog While Debugging

I'm writing unit tests in IronPython.


The implementation of unittest.main() calls sys.exit() when finished
even if no testing errors occurred. Consequently, the Visual Studio
debugger presents a dialog indicating that the SystemExit exception was
unhandled.  Running from the console, I do not see any evidence of the
SystemExit exception. Because my colleagues are not familiar with
IronPython, seeing this error in the debugger will cause them to think
that some problem occurred on exit.


Although I suspect I can configure Visual Studio to ignore this
exception, I'd prefer not to because it may indicate an actual problem.


How can I determine if an IronPython script is running under the VS




Have a great day!
