tilaajahyväksyntätestaukseen

Tilaajahyväksyntätestaus, often abbreviated as UAT (User Acceptance Testing), is the final phase of the software testing process before a system is deployed into production. Its primary purpose is to validate that the developed software meets the business requirements and needs of the end-users or customers. Essentially, it's a test conducted by the intended users or clients to determine if the system is fit for purpose and if they are ready to accept it.

During UAT, real-world scenarios and business processes are simulated. Users typically execute test cases based on their day-to-day tasks and workflows. The focus is not on finding defects in the code itself, which is the responsibility of earlier testing phases like unit, integration, and system testing, but rather on confirming that the software functions as expected from a business perspective and provides the desired value.

The goal of tilaajahyväksyntätestaus is to gain confidence that the system will work correctly in the production environment and to achieve formal sign-off from the stakeholders. This sign-off signifies that the users have reviewed the software and are satisfied with its functionality, usability, and performance, paving the way for its official release. Issues identified during UAT are typically prioritized and addressed before deployment.
