[New-bugs-announce] [issue12376] unittest.TextTestResult.__init__ breaks under complex __mro__

[Ben Ranker]

New submission from Ben Ranker <branker at emory.edu>:

TextTestResult.__init__(...) calls super(TextTestResult, self).__init__() with no args. If a custom TextTestResult descendant has a complex inheritance hierarchy that puts another class between TextTestResult and TestResult in the __mro__, then that class doesn't receive the common stream, descriptions, and verbosity args. If it needs them to function then the __init__ chain explodes.

See attached breakunit.py for an example of this.
