What is Non-Functional Testing?            

Non-Functional Testing is one of the types of software testing which is used to check non-functional aspects of a software application. The major role of it is to test the performance of the system as per its parameters which must not be addressed by functional testing. It also comes under the black box testing technique.

                In other hands this testing can be easily understandable by checking that how many people can simultaneously login into a software application. Both Functional Testing and Non-Functional Testing are important in Software Testing to get the expected output results.

Working Process of Non-Functional Testing:

  • Initially, it performs testing to grow the efficiency, usability and portability of the product
  • It helps to decrease the production cost and risk in accordance with aspects of the product
  • Optimizes the way of product installation, setup, execution, management and monitorization
  • It collects and provides metric measurements over internal research and development
  • Finally, it helps to improve and enhance product behavior and technologies in use

Advantages:

  • While doing this testing meanwhile we can do functional testing for some part of the software system
  • Huge range of security will increase against sudden attacks from internal and external sources
  • It helps to increase the performance and decrease the production cost and risk
  • Very flexible to work in any hardware and software configurations
  • Interference of one software system with other software system can be easily operated simply called as interoperability

 Disadvantages:

  • While doing new testing each time system need to get a modification
  • Required various number of software testing tools
