Common SQA Engineer Interview Questions

1. What is a potential risk in test automation, and how would you mitigate it?

Test automation is a valuable tool, but it can create a false sense of security if not managed properly. Automated tests might not cover all edge cases or adapt well to changes, leading to undiscovered defects. Additionally, test scripts can become brittle and high-maintenance with frequent software updates. Recognizing these risks shows foresight and the ability to address challenges before they impact development.

How to Answer: To address risks in test automation, acknowledge issues like maintenance complexity and insufficient coverage. Mitigate these by implementing a robust strategy with regular script reviews and updates. Combine automated and manual testing to cover edge cases. Use examples from past experiences to illustrate your proactive approach.

Example: “One potential risk in test automation is the maintenance burden that can occur when tests are too tightly coupled with the UI, particularly in applications that undergo frequent changes. This can lead to a situation where a minor change in the UI causes a large number of tests to fail, not because the functionality is broken, but because the tests need updating.

To mitigate this, I focus on building a robust test architecture that prioritizes the separation of the test logic from the UI layer. This involves using page object models or similar design patterns to abstract the UI interactions away from the test scripts. Additionally, I emphasize the importance of regularly reviewing and refactoring tests to ensure they remain reliable and relevant. By doing this, the team can focus on actual issues rather than spending excessive time on test maintenance.”
