What black-box test design technique involves creating test cases that execute representatives from equivalence partitions?

The correct choice, which focuses on the creation of test cases that execute representatives from equivalence partitions, is equivalence partitioning. This black-box testing technique is designed to reduce the number of test cases needed while maintaining adequate test coverage of the input domain.

In equivalence partitioning, the input data is divided into groups, or partitions, that are expected to exhibit similar behavior. Each partition represents a set of valid or invalid states that the input can take. The idea is that if one test case from a partition works (or fails), the others from that partition should behave similarly, allowing testers to efficiently identify potential defects without redundant testing.

For example, if an input field accepts values from 1 to 100, testing one value from 1-100 (valid partition) and one from any of the invalid partitions (like less than 1 or greater than 100) is often sufficient to confirm that the input is being handled correctly across its defined range.

Other techniques such as boundary value analysis specifically target the edges of input ranges rather than the values themselves; decision table testing organizes conditions and outcomes systematically for complex logic; state transition testing focuses on the different states an application can be in and tests the transitions between these states. Therefore, these alternatives
