What’s a flaky test
A flaky test is a test that sometimes passes and sometimes fails. This usual happens randomly and is incredibly annoying.
What causes flaky tests
- Under powered resources
- Tests running in random order
- Tests not cleaning themselves up afterwards
- External programs or requests interfering with the tests
How to fix flaky tests
- Run tests more regularly
- Separate flaky tests and run them in isolation until fixed
- Only test what is needed based on what has changed
- Don’t ignore or skip tests if you can help it
- Check the environment
- Check inputs for non-deterministic values
- Check timeouts
- Check system resources
- Check for race conditions
- Check if there is any fixed order to the tests
- Keep your tests maintained.
