matt@matt-1005P:~/src/cpython$ ./python -m unittest test.test_concurrent_futures
Ran 79 tests in 62.554s

FAILED (errors=18)

Failures are due to test discovery picking up unintentionally exposed tests. By adhering to the test_cases protocol introduced in 3.2, this doesn't occur.

Patch attached.

I think the better solution would be to fix the test inheritance hierarchy: only concrete test classes should inherit from unittest.TestCase.

Then the code can be simplified by simply calling unittest.main(__name__).

I had missed this issue before; issue16968 tracks the same thing.

There are a couple of issues that the committed patch doesn't address.  Namely, the file still uses test_main, and there is no thread or process reaping when running the file via discovery.

Unfortunately, there's no clear-cut best solution in the other issue.  A couple months ago, Serhiy posted a question on python-dev[1] about how to solve it, which I haven't seen any replies to.  Antoine, do you have any suggestions?
