Non-Functional User Stories – Specification and Test

The presentation will show how non-functional requirements (NFA) can be specified at the story level in agile requirements engineering and how they can then be tested in a meaningful way. As practical examples, the non-functional areas of “usability” and “efficiency” will be presented in the lecture and shown how these can be specified in the form of user stories and what have to be considered in the tests of these NFAs. The following questions will be answered, among others: - What are the categories of non-functional requirements? - Which requirements specification technique can be applied in an agile environment for non-functional requirements? - How detailed should non-functional requirements be specified? - How do you formulate tests for non-functional requirements? - When is the best time to specify the user interface and other details?
