New submission from William Schwartz:
In Python 2.7 and 3.3, decorating a unittest.TestCase subclass with
unittest.expectedFailure caused test discover to skip the decorated test case.
Python 3.4 apparently ignores the decorator when applied to classes.
The attached file when run with Python 2.7.6 on Mac OS X produces the following
output
$ python -m unittest discover
F.
======================================================================
FAIL: test_fails (test.TestControl)
----------------------------------------------------------------------
Traceback (most recent call last):
File "/Users/schwartz_w/Documents/testtest/test.py", line 9, in test_fails
self.assertFalse(True)
AssertionError: True is not false
----------------------------------------------------------------------
Ran 2 tests in 0.000s
FAILED (failures=1)
When run with Python 3.4.0 produces the following output.
~/Documents/testtest $ python3 -m unittest discover
F.F.
======================================================================
FAIL: test_fails (test.TestControl)
----------------------------------------------------------------------
Traceback (most recent call last):
File "/Users/schwartz_w/Documents/testtest/test.py", line 9, in test_fails

======================================================================

The expectedFailure decorator when applied to a class should either skip the
class or run all of its tests and check that they failed for consistency with
how expectedFailure applies to test methods.
