Difference Between Functional Testing and Non-Functional Testing

What do you mean by non functional testing?

The non functional Testing is the kind of testing done against the non functional needs. The vast majority of the criteria are not considered in functional testing so it is utilized to check the availability of a system


Non Fuctional Testing

Non functional testing affects client and client satisfaction with the product. Non functional testing is expected to be told in a testable manner “the software should be fast” or “the software ought to be easy to operate” which is not testable.


Cont.....

The testing of software properties which are not identified with a particular function or client activity like execution, adaptability, security or behavior pattern of application under specific limitations.


Non Functional Testing Types

  • Load testing

  • Reliability testing

  • Performance testing

  • Security testing

  • Volume testing

  • Installation testing

  • Localization testing and internationalization testing

  • Recovery testing

  • Stress testing and many more……


What do you mean by functional testing?


Five stages required to remember in case of Functional testing:

  • Arrangement of test data in light of the requirements of the function.

  • Business necessities are the inputs to functional testing.

  • In light of functional specifications, discover of output of the functions.

  • Executing the test cases.

  • Watch the actual and expected results.


Following types of testing need to be covered under functional testing

  • Sanity testing

  • System testing

  • Integration testing

  • Smoke testing

  • Regression testing

  • User Acceptance testing etc..


Functionality testing involves checking the following

  • Installation and setup on localized systems running localized operating systems and pages with local code.

  • Content handling, (for example, copying, pasting, and altering) of augmented characters, extraordinary textual styles, and non-Latin scripts.

  • String taking care of, content, and information, particularly when interfacing with non-Unicode applications or modules.

  • Content info, including the utilization of augmented characters or non-Latin scripts.

  • Core application functions.

  • Regional and other localized settings etc.

  • Exact hot key shortcuts without repetition.


This was regarding functional and non functional testing.
