Release Notes

pytest-dev/pytest-rerunfailures (pytest-rerunfailures)

v16.5

Compare Source

Features
++++++++

• Add --max-suite-reruns option to cap the total number of reruns across
  the entire test suite. Once the limit is reached, no further reruns occur
  regardless of per-test --reruns or @pytest.mark.flaky settings.
  (#&#8203;298 <https://github.com/pytest-dev/pytest-rerunfailures/issues/298>_)

Bug Fixes
+++++++++

• Create a new test class instance for each rerun. Previously the instance of
  the failed attempt was reused, so state stored on self leaked into the
  rerun and broke test isolation. Fixtures cached at class scope or higher are
  still not re-executed. (#&#8203;268 <https://github.com/pytest-dev/pytest-rerunfailures/issues/268>_)
• Prevent a rerun when a fixture teardown raises an error matching
  --rerun-except. Previously only the error from the current test stage was
  considered, so a --rerun-except-matching error raised during teardown was
  ignored and the test was rerun anyway. (#&#8203;270 <https://github.com/pytest-dev/pytest-rerunfailures/issues/270>_)
