bpo-34185: Fix test module collision in test_bdb when ran as script. (GH-8537)

miss-islington · lajarre · web-flow · commit bacc272afc16 · 2018-12-05T12:04:57.000-08:00
When running test_bdb.py as a script, `import test_module` would be importing the existing Lib/test/test_modules.py instead of the tempcwd/test_module.py module which was dynamically created by test_bdb.py itself. (cherry picked from commit 54fd455) Co-authored-by: Alex H <1884912+lajarre@users.noreply.github.com>
