If an end-to-end test fails, what was usually done?

If an end-to-end test fails, the first steps usually are:

1. Check the test and application logs to understand where exactly the error occurred.
2. Ensure that the test environment is correctly configured and all dependencies are available.
3. Verify whether the interface or business logic that the test checks has changed.
4. If the test is unstable, try to reproduce the error locally and analyze the causes of flakiness.
5. If necessary, fix the test or the bug in the code, and then rerun the tests.

It is important not just to fix the test, but to understand what exactly caused the failure to avoid false positives and improve product quality.
