Functional testing is a type of software testing by providing appropriate input which verifies that each function of the software application operates in conformance with the requirement specification. This testing mainly involves black box testing and it is not concerned about the source code of the application. This testing involves checking of User Interface, APIs, Database, security, client/ server applications and functionality of the Application under Test. The testing can be done either manually or using automation

During functional testing, Black Box Testing technique is used in which the internal logic of the system being tested is not known to the tester (QA).

Functional testing is normally performed during the levels of System Testing and Acceptance Testing.

Arivon Technologies Functional testing involves the following process:

• Identify functions that the software is expected to perform.
• Create input data based on the function’s specifications.
• Determine the output based on the function’s specifications.
• Execute the test case.
• Compare the actual and expected outputs.

Functional testing is more effective when the test conditions are created directly from end user/business requirements.

The main objective of Functional testing is checking the functionalities of the software system.

• Mainline functions:  Testing the main functions of an application
• Basic Usability: It involves basic usability testing of the system. It checks whether an end user can freely navigate through the screens without any difficulties.
• Accessibility:  Checks the accessibility of the system for the end user
• Error Conditions: Usage of testing techniques to check for error conditions.  It checks whether suitable error messages are displayed.
