Is it possible for a unit test to assert that a method calls sys.exit()?

Question

I have a Python 2.7 method that sometimes calls

sys.exit(1)

Is it possible to make a unit test that verifies this line of code is called when

Answer 1

I found the answer to your question in the Python Unit Testing documentation search for "Testing for Exceptions". Using your example, the unit test would look like the following:

self.assertRaises(SystemExit, your_function, argument 1, argument 2)

Remember to include all arguments needed to test your function.
