creating-debug-tests-and-iterating

External debugging tests interact with your application's public interfaces rather than internal components. Create a script that calls your CLI or API endpoints, run it against the live application, inspect logs for the bug, then iteratively adjust the script until the issue surfaces and you can fix it.

Bugs in production environments often depend on real workflows, authentication, and data state. Build external-interface scripts that replicate those exact conditions—including API calls, CLI commands, and logging—then run them repeatedly while analyzing logs and refining your fix until tests pass consistently.

Enable comprehensive logging in your application, then create a test script that exercises the API or CLI flow where the bug occurs. Run the script, review logs for the failure point, update your script or fix the code, and repeat until the bug is resolved and your test passes reliably.

Yes. External debugging supports authenticated flows, multi-step interactions, and real-time logging. Build a script that handles login, performs the sequence of CLI or API calls that triggers the bug, then logs and reports results so you can iterate without manual testing.

External tests validate behavior through the same interfaces users encounter, catching bugs that only appear in realistic conditions—network latency, data state, authentication—rather than in isolated unit tests. This ensures fixes work in production environments.

After your external test script passes and the bug is fixed, verify all tests pass end-to-end, remove any temporary test data or logging added during debugging, and keep the test script as a regression guard for future iterations.
