<s>[INST] Python unittest - opposite of assertRaises? 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) 

 [/INST] try:
    myFunc()
except ExceptionType:
    self.fail("myFunc() raised ExceptionType unexpectedly!")
