Loppukäyttäjähyväksyntätestaus

Loppukäyttäjähyväksyntätestaus, often abbreviated as UAT (User Acceptance Testing), is a phase in the software development lifecycle where the end-users test the software to ensure it meets their business needs and requirements before the system goes live. The primary goal of UAT is to validate that the software is fit for purpose and acceptable to the intended users.

This type of testing is typically performed in a production-like environment, using real-world scenarios and data. The end-users, who are the actual people who will be using the software on a daily basis, are responsible for conducting these tests. They evaluate the software's functionality, usability, and performance from their perspective.

UAT is a critical step because it helps identify any issues or discrepancies that may not have been caught during earlier testing phases. It ensures that the software aligns with business processes and that users are comfortable and confident in using the new system. Successful completion of UAT often signifies that the software is ready for deployment and release to the wider user base. It bridges the gap between development and actual business implementation.
