Detects thread leaks
Detects tests leaking threads
$ pip install pytest-threadleak
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
If you want to enable thread leak on a per test/module basis, you can use the threadleak pytest marker:
To enable it for a single test:
@pytest.mark.threadleak def test_leak(): ...
To disable it for a single test:
@pytest.mark.threadleak(enabled=False) def test_leak(): ...
For an entire test module:
import pytest pytestmark = pytest.mark.threadleak(enabled=False)
If you want to exclude some threads from the leak check, you can specify a regex to match excluded thread names:
[pytest] threadleak = True threadleak_exclude = pool/\d+
