Have you ever had to translate tests from one level to another (for example, from E2E to integration/component)?

Yes, I have had to translate tests from one level to another. For example, when E2E tests turned out to be too slow and fragile, I would extract integration or component tests from them to verify key logic without the need to run the full stack.

This allowed for faster feedback and error localization. When translating, it is important to identify dependencies and mock external services to keep tests isolated. This approach improves coverage and speeds up the development cycle.
