No. The package is abandoned (last release 2019-02-12, no updates for 2740 days) and compatibility with modern Django and Python versions is unverified. Modern Django includes built-in test timing features and third-party test runners have better maintenance. Use only if you are locked to Django 1.6–1.11 and Python 2.7 or 3.6.AI-flagged interpretation of the facts on this page — verify before relying
Before you install
- Requires Django and Python; compatibility with versions released after 2019 is not documented or verified.
- High install friction due to lack of runtime dependencies but the package is abandoned as of 2019-02-12 with no updates for 2740 days.
- Last commit was 2021-11-23, but the project shows no active maintenance.

Verify before relying
pip install django-slowtests

NUM_SLOW_TESTS = 10
SLOW_TEST_THRESHOLD_MS = 200
# Run tests:
python manage.py test- Whether the package works with Django versions released after 1.11 (last tested version in docs)
- Whether the package is compatible with Python 3.7+ (docs only mention up to 3.6)
- Whether the package's test runner integrates correctly with modern Django test discovery
What it is and what it does
django-slowtests is a Django test runner plugin that wraps the standard test runner to automatically measure and report execution time for each test. After your test suite completes, it displays a ranked list of the slowest tests, optionally filtered by a configurable threshold. You can save the report to a JSON file for further analysis.
The package has no runtime dependencies beyond Django itself and integrates by replacing Django's TEST_RUNNER setting with a custom runner class. It was designed for Django 1.6–1.11 and Python 2.7 and 3.6, but has received no updates since 2019 and is no longer actively maintained.
Use it for
- Identify which tests are consuming the most time during a test run to prioritize optimization efforts.
- Export test performance data to JSON for trend analysis or integration with CI/CD dashboards.
- Set a threshold to focus on tests exceeding a specific duration, filtering out fast tests from reports.
- Diagnose performance regressions by comparing slow test reports across different versions or branches.
