An Introduction About Non Functional Testing

Nonfunctional testing is a type of testing which is performed to check the performance, usability, reliability etc of a software application. This testing is designed to test the nonfunctional aspect of an application which is not addressed during functional testing.

Nonfunctional testing is also important for a software as functional testing.

Objectives of Non functional Testing

• Nonfunctional testing should perform to increase the usability, efficiency, maintainability, and portability of the software application.
• Helps to reduce cost associated and production risk with non-functional aspects of the software application.
• Optimize the way product is setup, installed, managed, executes and monitored.
• Improve and enhance the knowledge of software application. 

Non-functional testing Parameters:-

Security:

The parameters check system behavior against the sudden attack from an internal and external resource. This is done via Security Testing.

Reliability:

The parameters check that the system is able to perform specified function continuously without failure. This is done via Reliability testing.

Survivability:

The parameters check that the system is able to perform continues and recovers itself in case of system failure. This is done via Recovery Testing.

Availability:

The parameters check that the user can depend on the software system during its operation. This is done via Stability Testing.

Usability:

In this parameter user can learn, operate, prepare inputs and outputs through interaction with a system. This is done via Usability Testing.

Interoperability:

This parameter checks the software application interface with other other software application. This is done via Interoperability Testing.

Efficiency:

This parameter checks that the system can handle the response, capacity, quantity time. This is done via Efficiency Testing.

Flexibility:

This parameter checks that the software application is able to work in different hardware and software configuration.
