What is the term for data that a user is likely to input during testing?

The term for data that a user is likely to input during testing is normal data. Normal data represents the typical and realistic values that a user would expect to provide when interacting with a software application. This type of data is critical during the testing phase because it helps developers assess whether the program behaves as intended under standard conditions.

In contrast, error data refers to inputs that are intentionally incorrect or invalid to test how the system handles unexpected scenarios. Boundary data, on the other hand, focuses on inputs that fall at the limits of acceptable ranges, helping to identify issues at the edges of input constraints. Malicious data is designed to exploit vulnerabilities in the system, often used to test security features rather than everyday user behavior. By focusing on normal data, testers can verify that the application meets user expectations in typical usage scenarios.
