What test type is associated with validating typical customer behavior in an application through scripted data?

Use case testing is focused on validating typical customer behavior within an application by utilizing scripted data that reflects real-world scenarios. This type of testing examines how users interact with the application based on predefined use cases, ensuring that the software behaves as expected in common situations that a customer would encounter. By following these scripted scenarios, testers can confirm that the functionality meets user requirements and that specific interactions yield the expected outcomes.

This approach is crucial for verifying that the fundamental operations of the application align with the intents of the users, thereby enhancing user satisfaction and effectiveness. By contrast, other test types focus on different objectives, which is why they are not appropriate answers in this context. Exploratory testing, for example, involves testers exploring the application without specific scripts, emphasizing discovery and learning rather than validating predefined scenarios. Regression testing concentrates on ensuring that new code changes do not negatively affect existing functionalities, while performance testing assesses how the application behaves under various conditions, primarily measuring speed, scalability, and resource consumption rather than specific customer behaviors.
