Which of the following black-box test techniques should you use to test the processing functionality of this system?

You are testing the processing of a critical traffic control system to which various regulations apply. The processing of the input variables is dependent on defined ranges within which the actual retrieved data values can lie.

Which of the following black-box test techniques should you use to test the processing functionality of this system?
A . Use case testing
B . Pairwise testing
C . Equivalence partitioning enhanced with boundary value analysis
D . State transition testing

Answer: C

Explanation:

Equivalence partitioning is a black-box test technique that divides the input domain of a system into partitions of equivalent data. Boundary value analysis is a technique that tests the boundaries of these partitions, where errors are more likely to occur. These techniques are suitable for testing the processing functionality of a critical traffic control system, as they can ensure that the system handles the input variables within the defined ranges and detects any invalid or out-of-range values.
