Chapter 4 in Advanced Level Syllabus 2012 - Test Analyst: Testing Software Quality Characteristics

The Test Analyst should concentrate on the software quality characteristics of functionality and usability. Accessibility testing should also be conducted by the Test Analyst.

Testing for the other quality characteristics is usually considered to be the responsibility of the Technical Test Analyst.
