Käyttäjäacceptanssitesti

Käyttäjäacceptanssitesti, or User Acceptance Testing (UAT), is a crucial phase in the software development lifecycle. It is the final stage of testing before a new system, application, or software is released into production. The primary purpose of UAT is to verify that the system meets the business requirements and user needs defined at the beginning of the project.

During UAT, end-users or representatives of the target audience test the software in a realistic environment. They execute predefined test cases and scenarios that mimic real-world usage. This hands-on testing helps to identify any defects, usability issues, or discrepancies between what the system is supposed to do and what it actually does from an end-user perspective.

The success of UAT is often determined by whether the stakeholders formally accept the system for deployment. If the UAT is successful, it signifies that the software is ready to be released to the wider user base or to go live. If issues are found, they are documented, prioritized, and then addressed by the development team before a subsequent round of testing.

UAT is essential for ensuring customer satisfaction and minimizing the risk of costly post-release problems. It provides a final opportunity to catch errors and confirm that the system delivers the intended value to the business and its users. The process is typically performed after system testing and integration testing are completed.
