Module digint.tests.user_int_tests
user_int_tests
Holds test cases that specifically test the UserInt and ExtendedUserInt classes.
Classes
class ExtendedUserIntTests (methodName='runTest')-
Tests for the
ExtendedUserIntclass.Create an instance of the class that will use the named test method when executed. Raises a ValueError if the instance does not have a method with the specified name.
