I want to test that a function executes os._exit(2) on fail. I have seen many solutions with sys.exit() using SystemExit. I have read both the Python3 and the Python2 documentation and it seems that os._exit() doesn't use SystemExit
Nevertheless, I have tried this in case it was a misunderstanding of the documentation on my side, but it just exits nosetest, it's not even a test failure :
make: *** [test] Error 2
This is probably due to the function calling os._exit(2)
