What are some effective strategies to reduce flaky tests?

To reduce flaky tests, consider implementing the following strategies: 1. Ensure test isolation, 2. Use stable test data, 3. Avoid timing issues, 4. Regularly review and refactor tests.

Can you explain what test isolation means?

Test isolation means that each test should run independently of others, ensuring that the outcome of one test does not affect another.

How can I ensure stable test data?

You can ensure stable test data by using fixed datasets, mocking external services, and resetting the database state before each test.

What are some common causes of flaky tests?

Common causes of flaky tests include timing issues, dependencies on external systems, and shared state between tests.

How often should I review my tests for flakiness?

It's a good practice to review your tests regularly, ideally after every sprint or release, to identify and address flaky tests.
