pytest-threadleak 0.2.0

Detects thread leaks

Detects tests leaking threads

Installation

You can install “pytest-threadleak” via pip from PyPI:

$ pip install pytest-threadleak

Usage

The threadleak pytest plugin will fail leaking threads. This can be an issue in the test, or in the tested code.

Here is an example leaking test:

$ cat leak_test.py
import threading
import time

def test_leak():
    threading.Thread(target=time.sleep, args=(1,)).start()

Here is an example run with thread leak plugin enabled:

$ pytest --threadleak leak_test.py
...
leak_test.py::test_leak FAILED
...
>   ???
E   Failed: Test leaked [<Thread(Thread-1, started 139762716391168)>]

If you want to enable thread leak by default, you can enable it in your pytest.ini or tox.ini:

[pytest]
threadleak = True

Contributing

Running the tests:

$ tox
