23. What is the role of exploratory testing in your QA strategy?

Exploratory testing goes beyond scripted test cases and engages creativity, intuition, and experience. It allows for the discovery of unseen issues by encouraging testers to think like users and explore software in an unscripted manner. This approach reveals edge cases and unexpected behaviors, showcasing adaptability and critical thinking skills.

How to Answer: Articulate understanding of exploratory testing and its benefits, balancing it with other testing methods. Use examples where exploratory testing discovered significant issues or improvements. Integrate exploratory testing into the broader QA strategy, complementing automated and manual scripted testing.

Example: “Exploratory testing plays a crucial role in my QA strategy, acting as a complement to structured testing methods. While automated tests and predefined test cases ensure coverage of known requirements and previously documented bugs, exploratory testing allows the team to dive into the application with a fresh perspective, uncovering issues that might not be immediately apparent. It encourages testers to use their experience and intuition to find edge cases and unexpected behaviors.

In a previous project, we had a complex feature that passed all automated and manual test cases, yet users were still reporting issues. I organized exploratory testing sessions where team members, including developers and product managers, interacted with the feature as if they were end-users. This collaborative approach not only identified several usability concerns that were missed in structured testing but also fostered a deeper understanding of the product across the team. This experience reinforced the importance of integrating exploratory testing as a regular practice in our QA processes.”
