Enable plugin and use @fail_slow decorator to set per-test maximum duration in seconds.

# conftest.py pytest_plugins = ['pytest_fail_slow'] # then in test import pytest from pytest_fail_slow import fail_slow @fail_slow(0.5) def test_fast_enough(): import time time.sleep(0.1) assert True

Debug

Known issues

gotchaThe @fail_slow decorator must be applied after @pytest.mark.slow or similar markers; order matters because the decorator reads the test's current marker info.

fix

Place @fail_slow closest to the function, above other custom decorators.

affects: all

gotchaThe plugin only works with pytest's default runner; custom runners may silently ignore the fail_slow marker.

fix

Use the default pytest runner.

affects: all

deprecatedThe CLI option --fail-slow is deprecated in v0.6.0; use --fail-slow-seconds instead.

fix

Use `--fail-slow-seconds <seconds>` from command line.

affects: >=0.6.0
