What is User Acceptance Testing
User Acceptance Testing is the most important and final step of software testing process. It involves end to end testing of software applications in real time environment by end users to ensure that the applications meets the requirements of customers and organizations.The prime focus of User Acceptance Testing is to test the user friendliness, functionality and performance of software application as per customer requirements and expectations. User Acceptance Testing allows end users to thoroughly test the software application to make sure that it meets the requirements and performs as expected and helps to identify any fix any defects before final release.
Types of User Acceptance Testing
There are various types of User Acceptance Testing which are as follows:
Alpha Testing
Alpha testing is an important phase in software testing performed by both the development and testing team. It focuses on detecting and fixing defects in a controlled environment that mimics real time scenarios. This ensures the performance, scalability, reliability and functionality of the software application. Alpha testing uses a combination of white box and black box testing techniques for testing the functionality and performance of software applications. This results in increasing the quality of software applications and better user experience before final release of product.
Beta Testing
Beta testing is a process of testing software applications in a real time environment before final release. It is an important aspect of the software development process since it helps to detect and fix all the critical issues of software applications that might have been missed during the software development process. In Beta testing, the software is being given to a specific group of people to test its functionality ,evaluate its performance and provide the necessary feedback to developers. On receiving the feedback, the developers make necessary changes like adding new features, removing existing features and bug fixes so as to increase the efficiency of application and make it more user friendly before releasing to market.
Contract Acceptance Testing(CAT)
Contract Acceptance Testing is a type of software testing process which involves testing the functionality and performance of the software applications as per the requirements mentioned in the contractual agreement. It focuses on testing the user friendliness, stability, scalability,functionalities and performance of software applications as per the criteria,terms and conditions and quality standards mentioned in contract documents before being released into the market.
Operational Acceptance Testing(OAT)
It is a type of acceptance testing which checks whether the product is ready to be released into the market. It involves testing the operational features of software applications like backup, recovery and maintenance in an environment similar to a production environment. It is mostly used for software development and software maintenance projects. It also checks whether the software is ready to perform all the functions as per the client requirements and expectations.
Regulatory Acceptance Testing(RAT)
This type of software testing is done to ensure that the software application follows the rules and regulations set up by the government of a country before its release into the market. The main purpose of Regulatory Acceptance Testing is to ensure that the software meets all legal criterias as well as it is safe to be used by everyone. This type of testing is mostly used in the finance and healthcare domain.
End-User Acceptance Testing(EAU)
It is a type of testing which involves testing the functionality, performance, reliability and scalability of software applications by real users as per the requirements and expectations. The main aim of End User Acceptance Testing is to make sure that the application performs according to customer requirements and expectations in the real world scenario.It is generally performed by a group of real users before software release. During EAU users perform various actions on the application and give feedback based on their experience. All the issues and feedback are collected and sent to developers.
Black Box Testing
It is a type of testing which involves testing the functionality of software applications thoroughly and rigorously as per the customer requirements without focusing on the internal logic of the software application. Black Box testing involves testing the behaviour of software application without focusing on source code verification thus ensuring seamless user interaction.
Exploratory testing
This type of testing involves complete exploration of software application for understanding the requirements and identifying the functionalities ,testing those functionalities and finding out those defects which were not covered in the test case template. In exploratory testing,testers select any testing methodology of their choice to test the application.Developers utlise their skills and expertise to test the application developed by themselves.The exploratory testing provides a systematic approach to software testing by combining the skills, knowledge and experience of testers.
