Topic: Functional - Nonfunctional testing

Message

You got your terms mixed up, and if you are not careful you would be advised as follows:

1) Functional testing is performed by someone who is quite aware of what they are looking for;
2) Nonfunctional testing is performed by someone with no idea of what they are looking for;
3) The difference is that you get what you pay for, I suppose.

What
you are referring to is requirements. What a set of functional
requirements define is exactly what is needed to support the business
operation. What non-functional requirements define are all the other
types of requirements that relate to an operating environment,
standards, interfaces, and those kinds of things that are not unique to
the business operation. As a tester you should verify that all
requirements are satisfied regardless of their source classification.

The
main difference? For many non-functional test scripts you can reuse the
same tests (adapted to a specific user interface if necessary) to make
sure that the application is properly coded, and for functional
requirements you always have to create unique tests.
