Have you ever had to write or maintain end-to-end tests independently?

Yes, I have had to write and maintain end-to-end (E2E) tests myself. In my practice, I used tools like Selenium, Cypress, and Playwright to automate the full user scenario — from page load to interaction with elements and result verification.

Maintaining E2E tests includes:

• Updating tests when UI or logic changes.
• Optimizing tests to reduce execution time.
• Ensuring test stability to minimize false positives.

For example, in a web application project, I wrote tests that checked user registration, authentication, and main business processes, which allowed for quick regression detection during releases.
