How to Fix Flaky Tests?

To fix flaky tests, follow these focused steps:

• Rerun the test to confirm flakiness: Run the test multiple times. If it passes and fails inconsistently, it's flaky.
• Run the test in isolation: This helps identify if shared state or other tests are affecting it.
• Capture failure details: Use logs, screenshots, and test recordings to gather debugging data.
• Find the root cause: Common issues include timing problems, dynamic data, unstable environments, or external service dependencies.
• Fix the issue:
  • Replace hardcoded timeouts with smart waits
  • Use fixed or mock test data
  • Isolate test environments and clear state before each run
  • Use stable and specific element selectors
  • Stub or mock external dependencies
• Limit retries: If you enable retries, keep them minimal and only as a temporary measure.
• Track and tag flaky tests: Mark flaky tests clearly in your test management system until they are resolved.

By systematically identifying, isolating, and correcting the cause, you can eliminate flaky tests and make your test suite more reliable.
