Introduction to Non-Functional Testing — quiz

A login page accepts correct credentials and returns the right user dashboard, but takes 8 seconds to load on a standard broadband connection. Which statement best describes this situation?

• The application has a functional defect that blocks the login flow
• The functional behaviour is correct, but there is a non-functional (performance) defect
• This is an acceptable trade-off and requires no further testing
• Only unit tests can detect this kind of issue
