Python unittest - opposite of assertRaises?

Question

I want to write a test to establish that an Exception is not raised in a given circumstance.

It\'s straightforward to test if an Exception is raise

Answer 1

I am the original poster and I accepted the above answer by DGH without having first used it in the code.

Once I did use I realised that it needed a little tweaking to actually do what I needed it to do (to be fair to DGH he/she did say "or something similar" !).

I thought it was worth posting the tweak here for the benefit of others:

    try:
        a = Application("abcdef", "")
    except pySourceAidExceptions.PathIsNotAValidOne:
        pass
    except:
        self.assertTrue(False)

What I was attempting to do here was to ensure that if an attempt was made to instantiate an Application object with a second argument of spaces the pySourceAidExceptions.PathIsNotAValidOne would be raised.

I believe that using the above code (based heavily on DGH's answer) will do that.
