# Contributing

This is a quick reference for Click-specific development tasks. For setting up the development environment and the general contribution workflow, see the Pallets quick reference and the detailed contributing guide.

## Extra Test Environments

Click includes some extra test environments:

- `tox r -e stress` runs stress tests for race conditions in Click’s test runner.

      $ tox r -e stress

- `tox r -e random` runs tests in parallel in a random order to detect test pollution.

      $ tox r -e random

- A CI workflow (`.github/workflows/test-flask.yaml`) runs Flask’s test suite to catch downstream regressions.
