Which term refers to values at the limits?

• A. Extreme test data
• B. Abnormal test data
• C. Boundary test data
• D. Real

Answer: (A)

Testing values at the limits is about boundary testing. The standard term for this kind of data is boundary test data (also called boundary value analysis). It focuses on the edges of the valid input range—the minimum and maximum values, plus values just inside and just outside those limits—to catch issues like off-by-one errors or overflow. For example, if the valid range is 1 to 100, boundary data would include 1, 100, and also 0 and 101 to see how the program handles just outside the allowed range. Extreme test data isn’t the common term for limits, abnormal test data refers to invalid or unusual inputs, and real isn’t about testing limits.
