[IronPython] Prevention of SystemExit Dialog While Debugging

import System

Will determine if the debugger is attached or not.

Personally I hate code which checks this though but your usage sounds safe enough :)

Subject: [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 debugger?


Have a great day!
