How To Test Non Functional Requirements

This page is about testing non-functional requirements. Some of the non-functional requirements are:

• Scalability
• Performance
• Security
• Availability
• Reliability

These are aspects of a system that need to be verified somehow, preferably with automated tests, of course. But how?

Other non-functional requirements might be:

• Maintainability
• Extendability
• Reuseability

These are probably not verifiable by automated tests. (JayDepend? can run as a JUnit test, failing on e.g. circular package dependencies.)

The topic of testing non-functional requirements came up on InfrastructureInXp. --PeterGassmann
