ATA: ISTQB Advanced Level Test Analyst

SUMI provides structured feedback on users’ perceived usability, use case testing evaluates realistic user interactions and transaction flows, and heuristic evaluation efficiently identifies usability issues through an expert review. These techniques directly assess usability without the resource demands of a usability laboratory. Equivalence partitioning and pairwise testing are primarily techniques for selecting functional input combinations rather than evaluating usability. ISTQB describes use case testing as behavior-based testing that emulates intended use of the system.
