nosetests error "TypeError (Cannot extend enumerations)" #1056

Closed abcondas closed 7 years ago

abcondas commented 7 years ago

I've created a testsuite.py module that sets up a python testsuite. This module imports an enum class with 3 members:

# test_helper.py
class TestType(Enum):
    ONE = 1
    TWO = 2 
    THREE = 3
# testsuite.py
...
from test_helper import TestType
... create, add, and run testsuite

when I execute this module using nosetests I receive the error: Failure: TypeError (Cannot extend enumerations) ... ERROR

nose seems to be doing discovery and attempts to extend the enum class which is not allowed in python. Seems like a bug. Please advise.

Nose looks for classes whose names begin with ‘Test’ and considers those tests to be run. Perhaps your example would work as you would expect, if it had a name that did not being with 'Test'

Thank you, Rob! That was it. I should have figured that out... (blush)
