New submission from Martin Panter:
The documentation for "unittest.TestCase" says "the standard implementation of
the default 'methodName', runTest(), will run every method starting with 'test'
as an individual test". However:
>>> from unittest import *
>>> class Test(TestCase):
... def test_method(self): pass
...
>>> t = Test()
>>> t.run()
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "/usr/lib/python3.4/unittest/case.py", line 552, in run
testMethod = getattr(self, self._testMethodName)
AttributeError: 'Test' object has no attribute 'runTest'
After further experimentation, I see that if my test method is called
"runTest", it can be automatically discovered, but only if there are no other
test- prefixed methods.
Perhaps you could drop the end of the second paragraph for TestCase, so that it
just reads:
Each instance of TestCase will run a single base method: the method named
"methodName".
I think the details about the test- prefix and counting results are covered
elsewhere, and in most uses you wouldn't instantiate a TestCase yourself, so
changing the method name is irrelevant.
Also, perhaps under "TestLoader.loadTestsFromTestCase" it should say:
If no methods with the usual name prefix are found, but the "runTest" method is
implemented, there will be a single test case using that method.
