User acceptance testing (UAT) is a process by which a product is tested by representatives of the intended end-users to determine if it meets their needs and expectations.
The goal of UAT is to ensure that the product is ready for release, and that users will be able to successfully use it once it is released. UAT can be used to test any aspect of a product, from its functionality to its usability.
UAT (for software dev.) is typically performed near the end of the software development cycle, after the product has been coded and tested but before it is released to the public. However, it can also be used in the early stages of product development, to help identify potential problems and user needs.
UAT can be conducted in a number of ways, but usually involves having users test the product in a simulated environment, such as a test server or virtual machine. This allows developers to track any errors that occur and make changes before the product is released.
The main objective of UAT is to ensure that the software system meets all the functional and non-functional requirements specified by the customer or user. It also helps identify any issues or defects in the system before it goes live.
UAT is typically performed by an independent team consisting of users, stakeholders, and other interested parties who have knowledge about the application and its intended use. This team will evaluate whether or not the software meets their expectations and needs.
The duration of UAT depends on various factors such as complexity of features, size of user base, etc. Generally speaking, it can take anywhere from a few days to several weeks for a successful completion.
Fun Fact:
"User Acceptance Testing (UAT) is a critical part of the software development process, with 94% of organizations using UAT to ensure that their software meets customer requirements.” (Nguyen, 2019).
