CTFL-UT Exam Dumps : ISTQB Certified Tester-Foundation Level - Usability Testing

Common mistakes in usability testing include:

Ignoring critical results (ii): A significant issue if findings are not acted upon.

Scheduling the test too late (iv): This can lead to usability problems being discovered too late to be addressed effectively.

Having the wrong focus (v): For instance, focusing on aesthetics instead of usability goals.

Option i ("user is too active") is not a problem—active participation is necessary. Option iii ("no observers involved") is not a typical mistake, since tests can still be valid even with recorded sessions and later review. Hence, the correct answer is A: ii, iv & v are true.

The Web Content Accessibility Guidelines (WCAG) provide standards to ensure websites are accessible to people with disabilities. They specifically address:

i. Text resizability (SC 1.4.4),

iii. Text alternatives for non-text content (SC 1.1.1),

iv. Keyboard accessibility (SC 2.1.1),

v. Device independence, which includes not relying solely on mouse input.

Visually appealing design (ii) is not an accessibility requirement and is thus not a WCAG focus. The correct answer is D: i, iii, iv & v are true; ii is false.

A usability test participant is a person selected to represent the target user group and asked to perform specific tasks in a usability test. Their actions, reactions, and feedback help identify usability issues and evaluate the system’s effectiveness, efficiency, and user satisfaction. This role is strictly observational and does not involve organizing, observing, or setting up the test. Options A, B, and C describe other roles (e.g., technical support, observers, or moderators). Only option D accurately reflects the definition of a usability test participant.
