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.

Is your code calling unittest.main() or is Visual Studio calling it for you?

In the version of unittest that comes with Python 2.7 you can call unittest.main(exit=False). Alternatively you can just catch and ignore this exception yourself.

All the best,

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 debugger?

Thanks.

Have a great day!
