A Pytest plugin that allows you to loop tests for a user defined amount of time.

Project description

See Build Status on Travis CI PyPI version Python versions

A plugin that allows you to loop tests for a user-defined amount of time.


Only tested with Pytest version 5.2.2.


You can install “pytest-stress” via pip from PyPI (highly recommend installing in a Pipenv):

$ pip3 install pytest-stress


Loop tests for 30 seconds:

$ pytest --seconds 30

Loop tests for 45 minutes:

$ pytest --minutes 45

Loop tests for 8 hours:

$ pytest --hours 8

Loop tests for 1 hour 8 minutes and 9 seconds:

$ pytest --hours 1 --minutes 8 --seconds 9

Need to wait some time after each test loop? Don’t say I don’t love you:

$ pytest --delay 5 --hours 4 --minutes 30

You can also add these values to config files:

addopts = --hours 1 --minutes 30

Note: These loop times include setup and teardown operations as well. So if you have a test setup that takes 5 seconds, your actual tests will run for 5 seconds less than your desired time.


Contributions are very welcome! Tests can be run with tox, please ensure the coverage at least stays the same before you submit a pull request.


Distributed under the terms of the MIT license, “pytest-stress” is free and open source software
