[Pywikibot-commits] [Gerrit] [FEAT] tests: Add ability to easily patch parts - change (pywikibot/core)

jenkins-bot has submitted this change and it was merged. Change subject: [FEAT] tests: Add ability to easily patch parts ...................................................................... [FEAT] tests: Add ability to easily patch parts This adds the decorator `TestCaseBase.patched()` and the method `TestCaseBase.patch()` to easily patch something which is unpatched in `tearDown`. Each method with that `@patched()` decorator will be automatically patched into the given target. Anything more complex can be done manually with `patch()`.
