Release Notes

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

v16.7

Compare Source

Features
++++++++

• Allow configuring only_rerun regular expressions in pytest.ini files.
  (#&#8203;165 <https://github.com/pytest-dev/pytest-rerunfailures/issues/165>_)
• Show each rerun attempt and its final outcome in the rerun test summary info
  section. (#&#8203;191 <https://github.com/pytest-dev/pytest-rerunfailures/issues/191>_)
• Allow flaky marker conditions to inspect the exception that caused a failed
  test phase, including when running with pytest-xdist. (#&#8203;230 <https://github.com/pytest-dev/pytest-rerunfailures/issues/230>_)

Bug Fixes
+++++++++

• Match only_rerun against the full exception chain (__cause__ and
  __context__), not only the outermost exception. Match rerun_except
  against explicit __cause__ links only, so implicit except /
  finally context does not suppress reruns. (#&#8203;353 <https://github.com/pytest-dev/pytest-rerunfailures/issues/353>_)
• Fix INTERNALERROR when only_rerun or rerun_except is given a bare
  exception class instead of a list. (#&#8203;362 <https://github.com/pytest-dev/pytest-rerunfailures/issues/362>_)
• Fix subtest reruns with newer pytest versions that use structured NodeId
  values internally. (#&#8203;363 <https://github.com/pytest-dev/pytest-rerunfailures/issues/363>_)
• Mark teardown failures from an attempt that is rerun as reruns, so a later
  successful attempt is not reported as an error. (#&#8203;366 <https://github.com/pytest-dev/pytest-rerunfailures/issues/366>_)

Misc
++++

• Keep the test suite passing when pytest-randomly is installed, including when
  the outer pytest is started with -p no:randomly. (#&#8203;218 <https://github.com/pytest-dev/pytest-rerunfailures/issues/218>_)
• Test the free-threaded Python 3.14 build in CI, via a new py314t tox
  environment and a matching workflow job. (#&#8203;361 <https://github.com/pytest-dev/pytest-rerunfailures/issues/361>_)
