What else should a QA do besides writing automated tests to ensure feature quality?

In addition to writing automated tests, QA should:

• Analyze requirements and specifications to ensure they are complete and testable.
• Conduct manual testing to verify user experience and identify bugs that are difficult to automate.
• Plan testing, develop test strategies and scenarios.
• Perform regression testing after changes.
• Work with developers and managers to clarify requirements and quickly resolve issues.
• Track and document found defects, participate in their prioritization.
• Conduct load and stress testing if necessary.
• Ensure quality not only of functionality but also of performance, security, and usability.
• Maintain and update existing tests and test documentation.
• Participate in automation of testing processes and integration into CI/CD.

Thus, the role of QA is broader than just writing automated tests — it is a comprehensive assurance of product quality at all stages of development.
