The exploratory tester's role goes beyond finding bugs. It involves understanding user behavior, improving software quality, gathering feedback, and refining testing strategies. As an exploratory testing expert, you are an investigator who understands the software, uses creativity and intuition to guide the session, and discovers new ways to uncover hidden issues.
Moreover, mastering exploratory testing requires crafting effective test scenarios, navigating complex systems, quickly iterating based on feedback, analyzing data, and proactively identifying potential risks. And that’s where these recommendations come in! These 5 exploratory testing books offer practical advice, real-world examples of improving software quality, and innovative testing methods.
From the principles of exploratory testing to tester responsibilities and concepts like risk-based testing, session-based test management, and user-centered design, these books will help you improve your exploratory testing strategy.
James Whittaker exposes the hidden causes of today’s most challenging software bugs. He introduces new exploratory testing techniques designed to identify and fix these issues. With almost two decades of experience at leading companies like Google and Microsoft, Whittaker shares manual testing processes that are effective, structured, teachable, and repeatable.
Whittaker details techniques for individual testers and broader strategies to enhance the effectiveness of test teams. He also outlines a hybrid approach that integrates exploratory testing principles with traditional scripted testing methods. The book guides readers on when and how to apply each approach for maximum success.
The author also introduces the concept of Test Tours, a metaphor that can be used in exploratory testing to help you navigate the software’s complexity by providing a framework for organizing your testing and achieving your objectives. In these scenarios, you see yourself as a tourist (tester) exploring (testing) a new city (software). Your exploratory activities will change depending on the goals of your travels.
Written for testers, QA specialists, developers, program managers, and software architects, Whittaker answers questions such as:
