Software quality can be enhanced by different approaches that differ from functional testing, such as technical performance analysis, security testing, usability testing.

What is Non-functional Testing? Non-functional testing is an extensive part of software testing that obscures a lot of different aspects of software behavior. Some of the most usual non-functional tests that are identified and conducted on a regular basis are performance, capacity, and failover tests.

At present many IT projects disregard to test extra non-functional characteristics of the systems they implement, such as sustainability/soak test, recovery and operability. The area of non-functional behavior showed by an application and system combination is immense and further complicated by the sudden nature of events taking place in the target production environment. In a perfect world we would have an entire set of non-functional requirements that defines all elements of application behavior in a given environment and systems composition under a variety of custom patterns.

Reality of Non-functional Testing The reality is that, at the best, project teams are faced with a lean minimum set of requirements that define the expected response time for a set of critical online functions, a batch processing window, and high-level availability requirements. You should use another method that is different than the traditional functional requirements collecting and specification is required to get a list of non-functional requirements. Moreover to the minimum set of tests above, there are many extra tests that are critical to understanding and verifying the non-functional behavior of your application and system.

What Do We Advise? We believe that non-functional types of testing should be paid no less time than the functional testing and these efforts should be planned in the early stages of development. Main types of non-functional testing : • • • •

Performance testing (load testing, etc.) Failover testing Usability testing, Testing of Information Security.
