What is Functionality Testing?

Functionality testing is a type of software testing that validates the software system against the functional requirements/specifications. The purpose of functionality tests is to test each function of the software application, by providing appropriate input, verifying the output against the Functional requirements.

Functional testing mainly involves black box testing and it is not concerned about the source code of the application. This testing checks User Interface, APIs, Database, Security, Client/Server communication and other functionality of the Application under Test. The testing can be done either manually or using automation.

Therefore, functionality testing can be carried out via two popular techniques:

  • website theme designing

    Testing based on Requirements:

    Contains all the functional specifications which form a basis for all the tests to be conducted.

  • website theme designing

    Testing based on Business scenarios:

    Contains the information about how the system will be perceived from a business process perspective.

What do you test in Functionality Testing?

The prime objective of Functionality testing is checking the functionalities of the software system. It mainly concentrates on -

    Basic Usability:

    It involves basic usability testing of the system. It checks whether a user can freely navigate through the screens without any difficulties.

  • website theme designing

    Accessibility:

    Checks the accessibility of the system for the user.

  • website theme designing

Advantages of Functionality Testing

Let’s highlight various advantages of Functional Testing.

    Functionality testing is essential for evaluating the performance and the functionality of a software application before it is delivered to the end user for its real use.

    It is performed from the perspective of the users, which allows the development team to create test scenarios that represent the real world use scenarios.

  • website theme designing

    Allows the team to meet the requirements of the user as well as the client.

  • website theme designing

    It ensures the proper working of all the functionalities of an application/software/product.

  • website theme designing

    It ensures that the software/product works as expected.

  • website theme designing

    It ensures security and safety.

  • website theme designing

    It improves the quality of the product.

  • website theme designing

    The risks and loss associated with the product/software reduced.

Functionality testing is more effective when the test conditions are created directly from user/business requirements. When test conditions are created from the system documentation (system requirements/ design documents), the defects in that documentation will not be detected through testing and this may be the cause of end-users’ wrath when they finally use the software.
