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 raised ...

sInvalidPath=AlwaysSuppliesAnInvalidPath() self.assertRaises(PathIsNotAValidOne, MyObject, sInvalidPath)

... but how can you do the opposite?

Something like this I what I'm after ...

sValidPath=AlwaysSuppliesAValidPath() self.assertNotRaises(PathIsNotAValidOne, MyObject, sValidPath)

Answer 1

If you want to write a test to establish that an Exception is not raised in a given circumstance you can use the following piece of code:-

def run_test(self):

try:

myFunc()

except ExceptionType:

self.fail("myFunc()raised ExceptionType unexpectedly!")
