Project description


Plugin for adding a marker to slow running tests. 🐌


You can install pytest-snail via pip from PyPI:

pip install pytest-snail==0.1.0


When you run your tests, pytest-snail keeps track of test durations for each test item by test phase: setup, call, and teardown. ⏱

The next time you run your tests, pytest-snail adds a snail marker to all test items with a recorded, accumulated duration that is equal or longer than the value for the --snail CLI option (defaults to 5.0 seconds).

You can then use pytest's marker expressions to select or deselect tests.


First run your tests to measure test durations:


Then deselect all tests that take longer than 5.0 seconds to complete:

pytest -m "not snail"

Select only tests that take longer than 10.0 seconds to complete:

pytest --snail 10.0 -m snail
