What is Non-Functional Testing?

Non-Functional Testing occurs to be defined as one of Software testing that is used to check non-functional aspects(performance, usability, reliability, etc) that a software application makes out. An excellent example of the non-functional test occurs out to check how many people can simultaneously login in a software.

The non-functional test occurs out to be equally important since functional testing affects client satisfaction. Non-Functional Testing occurs out as one such testing of a software application or system for its non-functional requirements. It includes the way a system operates instead of specific behaviors of that system & its components.

The names of various non-functional tests often are used interchangeably just because of the overlap in scope between multiple non-functional requirements. For instance, software performance occurs out to be a broad term that involves various specific requirements like reliability & scalability.

Non-Functional Testing

Treat testing like a team effort.

Non-Functional Test Parameters

  • Security: This parameter defines how a system gets safeguarded against deliberate as well as sudden attacks through internal & external sources. This gets tested through Security Testing.
  • Reliability: The extent to which any of the software systems continuously performs out the specified functions without any kind of failure.
  • Survivability: The parameter checks out that the software system continues out to function & recovers itself out in case of the system failure. Recovery Testing checks it out in the right manner.
  • Availability: This parameter determines out the degree to which the user depends upon the system during its operation. Stability Testing checks it out perfectly.
  • Usability: The ease with which the user learns, operates, prepares inputs & outputs through interacting with a system. Usability Testing checks it out amazingly well.
  • Scalability: This term refers to the degree wherein any software application can expand out its processing capacity so as to meet an increase in demand. Scalability Testing tests it out in the right manner.
  • Interoperability: This non-functional parameter checks out a software system interfaces with other software systems. Interoperability Testing checks it.
  • Efficiency: The extent to which any software system handles out capacity, quantity as well as responsive time.
  • Flexibility: This term refers to the ease with which the application can work out in different hardware & software configurations. Like minimum RAM, CPU requirements.
  • Portability: The flexibility of software to transfer through its current hardware or software environment.
  • Reusability: It refers to the portion of a software system that gets converted for usage in another application.
