Which term is synonymous with 'wrong values used to test software errors'?

• A. Data types
• B. Abnormal test data
• C. Real
• D. Constants

Answer: (B)

Testing with inputs that are outside what the program expects is about ensuring robustness and proper error handling. The term that matches “wrong values used to test software errors” is abnormal test data. It covers values that are invalid, unexpected, or malformed—things a user or system might try that the program should reject or handle safely. For example, entering letters where a number is required, or a number outside an allowed range. This is distinct from data types, which are just categories of data; real refers to real-number values; and constants are fixed values used in code. So abnormal test data is the right description of using wrong values to probe error conditions.
