What is a primary reason for involving users during test execution?

Involving users during test execution is primarily about facilitating user acceptance and confidence in the system being tested. When users participate in the testing process, they gain firsthand experience with the application, which helps them understand its functionalities and limitations. This engagement not only allows users to evaluate whether the system meets their needs but also serves to build their confidence that the product will work as intended in real-world scenarios.

Furthermore, active participation by users can uncover insights that might not be apparent to testers with less domain knowledge. They can provide valuable feedback based on their perspective as end-users, which can help identify usability issues or unexpected behaviors. Ultimately, this collaborative approach enhances the likelihood of user acceptance once the product goes live, making it a crucial aspect of the testing process.
