Quality, as discussed in Concept: Focus Continuously On Quality, is not a simple concept to describe.
Likewise, when our focus turns to the discussion of testing to identify quality, there is no single perspective of what
quality is or how it's measured.
In the RUP, we categorize quality using the FURPS+ model [GRA92]:
+ (and others)
This is the same categorization scheme that we use in RUP for requirements, which is described further in Concept: Requirements.
For each of these dimensions, one or more individual types of tests (see Concept: Types of Test) should be implemented and executed during one or more of the different levels of test (see Technique: Stages of Test).
