Difference Between Functional Testing and Non-Functional Testing

Up till now, you must have seen separate articles for Functional Testing and Non-Functional testing. In any case, in today’s article we will see the real distinction 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. Requirements which are non functional have a tendency to be those that mirror the nature of the product, especially with regards to the reasonableness perspectives of its clients. It can be begun after Functional Testing is done. The non functional tests can be compelling by utilizing testing tools.

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.

Essentially in the non functional test is utilized to major non-useful properties of software frameworks. Here are some examples of non functional requirements; what amount of time does the software product take to finish a particular task? on the other hand, how quick the response time is.

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.

Here is some testing that should be considered in the 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?

It includes the complete integration framework to check the system’s consistence with its predetermined requirements. In view of the system requirement specification document, this kind of testing is to be done. In actual testing, testers need to confirm a particular activity or functioning of the code. For functional testing either manual testing or automation tools can be utilized however functionality testing would be simpler utilizing manual testing as it were. Before non Functional testing the Functional testing would be executed first.

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.

In order to implement functional testing, there are many tools available, that include test automation tools as well.

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 confirms that an application is still completely functional after localization. Indeed, even applications which are professionally internationalized by world-readiness rules require functional testing.

Functionality testing is performed to check that a product application performs and works accurately as indicated by design specifications. Amid functionality testing we check the center application functions, content input, menu functions and installation and setup on localized machines, and so on.

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.
