What is the difference between UAT user acceptance testing and system testing?
User Acceptance Testing (UAT) is a type of testing performed by the end user or the client to verify/accept the software system before moving the software application to the production environment. UAT is done in the final phase of testing after functional, integration and system testing is done. Show
In this UAT tutorial, you will learn:
Purpose of UATThe main Purpose of UAT is to validate end to end business flow. It does not focus on cosmetic errors, spelling mistakes or system testing. User Acceptance Testing is carried out in a separate testing environment with production-like data setup. It is kind of black box testing where two or more end-users will be involved. UAT is performed by – Need of User Acceptance TestingNeed of User Acceptance Testing arises once software has undergone Unit, Integration and System testing because developers might have built software based on requirements document by their own understanding and further required changes during development may not be effectively communicated to them, so for testing whether the final product is accepted by client/end-user, user acceptance testing is needed.
Acceptance Testing and V-ModelIn VModel, User acceptance testing corresponds to the requirement phase of the Software Development life cycle(SDLC). Prerequisites of User Acceptance Testing:Following are the entry criteria for User Acceptance Testing:
How to execute UAT TestsUAT is done by the intended users of the system or software. This type of Software Testing usually happens at the client location which is known as Beta Testing. Once Entry criteria for UAT are satisfied, following are the tasks need to be performed by the testers: UAT Process
Step 1) Analysis of Business RequirementsOne of the most important activities in the UAT is to identify and develop test scenarios. These test scenarios are derived from the following documents:
Step 2) Creation of UAT Plan:The UAT test plan outlines the strategy that will be used to verify and ensure an application meets its business requirements. It documents entry and exit criteria for UAT, Test scenarios and test cases approach and timelines of testing. Step 3) Identify Test Scenarios and Test Cases:Identify the test scenarios with respect to high-level business process and create test cases with clear test steps. Test Cases should sufficiently cover most of the UAT scenarios. Business Use cases are input for creating the test cases. Step 4) Preparation of Test Data:It is best advised to use live data for UAT. Data should be scrambled for privacy and security reasons. Tester should be familiar with the database flow. Step 5) Run and record the results:Execute test cases and report bugs if any. Re-test bugs once fixed. Test Management tools can be used for execution. Step 6) Confirm Business Objectives met:Business Analysts or UAT Testers needs to send a sign off mail after the UAT testing. After sign-off, the product is good to go for production. Deliverables for UAT testing are Test Plan, UAT Scenarios and Test Cases, Test Results and Defect Log Exit criteria for UAT:Before moving into production, following needs to be considered:
Qualities of UAT Testers:UAT Tester should possess good knowledge of the business. He should be independent and think as an unknown user to the system. Tester should be Analytical and Lateral thinker and combine all sort of data to make the UAT successful. Tester or Business Analyst or Subject Matter Experts who understand the business requirements or flows can prepare test and data which are realistic to the business. Best Practices:Following points needs to be considered to make UAT Success:
UAT ToolsThere are several tools in the market used for User acceptance testing and some are listed for reference: Fitness tool: It is a Java tool used as a testing engine. It is easy to create tests and record results in a table. Users of the tool enter the formatted input and tests are created automatically. The tests are then executed and the output is returned back to the user. What is difference between system testing and user acceptance testing?1. System testing is done to check whether the software or product meets the specified requirements or not. Acceptance testing is the type of testing which is used to check whether the software meets the customer requirements or not.
Is acceptance testing the same as user acceptance testing?The user acceptance test is performed by the users and application managers. The Operational Acceptance test: also known as Production acceptance test validates whether the system meets the requirements for operation.
What are the 4 types of acceptance testing?Types of acceptance testing include:. Alpha & Beta Testing.. Contract Acceptance Testing.. Regulation Acceptance Testing.. Operational Acceptance testing.. What is UAT user acceptance testing?User acceptance testing (UAT), also called application testing or end-user testing, is a phase of software development in which the software is tested in the real world by its intended audience.
