The doctests are executed with 'test.globs' as globals which is set in the 'find' method of doctest.DocTestFinder, and cleared after each run (unless 'clear_globs' is false). One possible fix is to have test.regrtest 'find' a new test_runner before each run instead of always using the same one. This is what does the attached patch. |
|
See also bpo-20766. |
|
test_statistics also defines a load_tests() function that builds unittest tests from doctests with doctest.DocTestSuite() and also fails in refleak mode. The above regrtest.diff patch also fixes the test_statistics in refleak mode. |
