Functional Testing ensures that any Product released to the customer should perform as expected.
Functional testing is carried out to verify whether each function of the software application functions as per the specification. Lack or improper functional testing might lead to faulty product reaching the users which has a negative effect on the overall reputation, user experience and other commercial impacts.
Functional testing is very crucial step in the overall testing process as it involves testing each and every functionality of the application. Typically, functional testing involves black box testing as it does not take in consideration the source code of the application.
Though functional testing is a common activity in the software testing process, it requires thorough understanding of the requirements from the application based on which proper test cases need to be designed. As the nature of software applications becomes function-heavy and complex, so becomes the functionality testing. Increased complexity significantly enhances the chances of functionality issues creeping in the application. Hence, it becomes critical that the team carrying out functional testing is well aware of all the functionalities and carries out testing for each of them.
Methodology of functional testing
Though functional testing is a single term, it is an activity comprising many sub activities. Functional testing involves testing each of the individual modules for correct functioning (unit testing) and then also analyses how these individual modules function together and work as per the specific requirements.
Depending on the nature of the application, functional testing may involve any or all of following testing activities:
Functional testing process begins with understanding the requirements of different functionalities of the application. This is the most crucial step as it determines the overall success or failure of the product. After the testing team gets the clear understanding of the functional requirements, various test inputs are selected to test each and every functional aspect of the application. An output for each input is computed. The fourth step involves actually executing the application for these selected inputs and then comparing these actual outputs with the computed outputs. Any gaps between the actual and computed outputs means presence of functional issues in the application then are de-bugged.
