comment Functionality in ISO 9126 is Non-functional quality? Contradiction in ISTQB and many sources
I see, I just cannot see the relation. When you look at the Functionality metrics (external from ISO 9126) I posted above, it seems exactly like testing (differences between exp and act. outputs etc.). I still miss the link - if it passes functional testing, what are these (I mean "functional") NFR good for?

1.1 Functionality metrics An external functionality metric should be able to measure an attribute such as the functional behaviour of a system containing the software. The behaviour of the system may be observed from the following perspectives: a) Differences between the actual executed results and the quality requirements specification; NOTE: The quality requirements specification for functionality is usually described as the functional requirements specification.

Really? Interesting, never heard that. This is quite an interesting topic. Anyway, sources saying that these are functional and need to be tested functionally..not sure what to think of that. So basically, if I get you right, you use functional testing to verify functional aspect of a non-functional quality - but at the same time, you verify functional reqs?

Thanks. I would think the same..however, I read the external metrics which mentioned measurements of individual sub-characteristics and - as adopted by some ISTQB books - they say e.g. Correctness - verify expected or implied output as stated in functional requirements. IMO this has nothinh to do with NFR! Im just confused...

@Robert Harvey: Maybe it is my English but I am not sure what you are saying. You say these qualitiies are non-functional (including Functionality) but I cannot see how?
