bpo-30523 added a new --list-cases command to regrtest to list test methods. It is able to list doctest tests in test_builtins, but not in test_extcall. test_builtin doctest tests: haypo@selma$ ./python -m test test_builtin --list-cases|grep ^builtins builtins.bin builtins.float.as_integer_ratio ... test_builtins works because it uses: def load_tests(loader, tests, pattern): from doctest import DocTestSuite tests.addTest(DocTestSuite(builtins)) return tests Listing test methods of test_extcall doesn't work, the following command has no output (but succeed): ./python -m test test_extcall --list-cases test_extcall uses: def test_main(): support.run_doctest(sys.modules[__name__], True) I see two options: * Replace support.run_doctest() with doctest.DocTestSuite() in all tests * Enhance --list-cases to discover doctests. support.run_doctest() calls doctest.testmod(), but doctest.testmod() has no API to list tests. testmod() lists tests and directly runs them. Maybe --list-cases can reuse doctest.DocTestSuite(), I don't know.
Note that --match (and --matchfile) is ignored by doctests. I think this can cause a problem for bisect feature. After making --match working with doctests we can found a way to name doctests and list them.
> Note that --match (and --matchfile) is ignored by doctests, so technically, it seems that it's doable ;-) In test_os, --match works on doctest tests: haypo@selma$ ./python -m test -v test_builtin --match=builtins.hex (...) 0:00:00 load avg: 0.28 [1/1] test_builtin hex (builtins) Doctest: builtins.hex ... ok ---------------------------------------------------------------------- Ran 1 test in 0.002s (...)
I have no idea how to implement this idea. I'm not interested to work on this topic, so I just close this issue. If someone wants to work on this topic, please open a new issue.
