New submission from STINNER Victor:
On Python 2.7, listing *all* test cases with "./python -m test --list-cases"
fails on the following test files:
* test_multibytecodec_support
* test_robotparser
regrtest of Python 2.7 uses the test_main() function of each test file, if the
function is defined. Whereas --list-cases is more written as a raw discovery
function listing all cases which inherit from unittest.TestCase. These 3 files
have base test cases which are "abstract" or configured below.
Options:
* Modify --list-cases to tolerate failures and report them at exit
* Modify these 2 tests to make them more "test discovery"-friendly
* Use test_main() function if available but modify its behaviour to only list
test cases, instead of running them
I would prefer to limit changes in Python 2.7 branch, so IMHO the second option
is the best: modify the 2 tests.
