The characteristic of the software product is ensured by the process of functional testing. This implies that before releasing the product, it should be thoroughly checked to see whether its functionality meets all the necessities.  Functional testing is the form of software testing that ensures whether the functions of an app are working following the required specifications. The purpose of this practice is to test each function of the software application.It mainly involves black box testing (method of software testing) where the tester does not know the internal system logic. Functional testing focuses on manual testing, along with automation testing. This type of testing includes checking the following: User Interface, APIs (application programming interface), Security, Database, Client Applications, and Feature of the application under test.Two popular techniques are involved in the process of functional testing. They are:Based on requirements – It includes all the technical specifications that form the basis for the entire test to be carried out.Based on Business set-up- It includes information regarding how the system will be identified from the viewpoint of the business process.Functional testing primarily concentrates on:Fundamental Usability- It comprises initial usability testing of the system wherein it confirms whether the user can navigate effortlessly through the screens.Core functionalities- It tests the critical functions of an application.User-friendliness- It verifies the accessibility of the system for the user.Faulty condition- It checks the error conditions and sees whether the appropriate error messages are correctly displayed.Features of functional testing:The functional testing technique is a way of quality assurance and authenticates the functionality of web applications.It serves as the black box testing along with specification-based testing.It makes sure that the software/product conforms to their particular functional requirements. Functional testing is not concerned about how the system processes.Various aspects mentioned in the requirement specification and functional specification document is verified with functional testing.The bases of test cases are the specifications of the component under test.Types of Functional Testing Many categories are involved in functional testing, and based on the scenario; it can be utilized. Let’s discuss the main types of functional testing:Unit Testing – Developers who write different code units perform this (unit testing) type of testing. These code units are written to attain a specific functionality, and it can be related or unrelated. Code coverage is an essential part of unit testing. The test cases cover line coverage, code path coverage, and method coverage.Integration Tests- After unit testing, the concept of integration tests gains attention. During unit testing, the unit is developed and is tested by itself. These units are integrated with the surrounding units in the program. The aim of this (integration) testing is to verify proper functionality between components. Due to this type of software testing, there is no need to retest every combination of lower-level functionality.Smoke Testing – This type of software testing is executed after the software is built to determine that the program's crucial functionalities are working well. This type of testing helps in building stability. It is also known as build verification testing. The objective of smoke testing is to discard a faultily broken application, which saves the team's precious time from installing and testing the software application.Sanity Testing – Generally, after the smoke test, this type of testing is done. The purpose of sanity testing is to ensure that all the primary and essential functionalities of the application or system are working correctly. If testers do not have sufficient time for testing, then this testing is carried out. It serves as the surface level testing.Regression test- This type of testing certifies that changes to the codebase (like new code, debugging strategies, enhancements, etc.) do not disturb the existing functions. The test cases in this type of software testing are re-executed to check the working of the previous functionality, and simultaneously it ensures that the new changes have not introduced any new bugs. Regression testing can be performed on a newly built code snippet or program.Beta/Usability testing – This type of testing aims to meet the user needs and confirms whether it works well for the users. The product is exposed to the customers in a production like an environment. After that, the product is tested. The user's comfort is derived from this situation, and then finally, the feedback is taken. Often, this type of testing is considered the last step before the software or any other feature goes live.Benefits of functional testing:It enhances the quality of the product and ensures that all the requirements are met efficiently.The right working of all the functionalities of an application/ software/product is ensured by functional testing.Any risk associated with the software or product decreases with the help of a functional testing technique, which also reduces the loss.Defect-free software/product is produced with the help of a functional testing technique. It makes sure that customer or end-user is satisfied.This type of test provides security and safety. It focuses that the software/product works as per the expectations.The team can spend more time writing test cases for new areas/modules due to the system's automation.The manual test of different functions can be done quickly and easily with the help of a functional testing technique.The actual system usage is stimulated due to the functional testing technique.It ensures that the system/application is working on all platforms efficiently.The development team can create test scenarios representing the real world used scenarios by employing a functional testing technique.Conclusive Statement Functional testing tests the system's functionalities and confirms whether the system is working according to the features mentioned in the business document. The objective of functional testing is to ensure that whether the system is functioning correctly. The functional testing technique checks the website, system, or application to ensure that it does what it is meant to do. It serves as an excellent instrument to perform business tasks efficiently.
