[issue25746] test_unittest failure in leaks searching mode

[Xiang Zhang]

Xiang Zhang added the comment:

Simple reproduction:

>>> pickle.dumps(unittest.loader._make_skipped_test('hello', RuntimeError, 
>>> unittest.suite.TestSuite))
Traceback (most recent call last):
  File "", line 1, in 
_pickle.PicklingError: Can't pickle : 
attribute lookup ModuleSkipped on unittest.loader failed

Exporting ModuleSkipped in unittest.loader can solve this. But maybe any more 
elegant method?

[issue25746] test_unittest failure in leaks searching mode

[STINNER Victor]

STINNER Victor added the comment:

While checking that I didn't introduce a reference leak recently with my 
changes around _PyObject_FastCall(), I found the same issue: test_unittest 
doesn't work with regrtest -R.

I get the same error:

$ ./python -m test -R 0:1 -v test_unittest
