Acceptance testing is formal testing conducted to determine whether or not a solution satisfies its acceptance criteria, and to enable the customer, user or authorized entity to determine whether or not to accept the system. Acceptance testing is often conducted at the development site, and then at the customer site using the target environment.
How the customer evaluates the deliverable artifacts, to determine whether they meet a predefined set of acceptance criteria, is described in the Acceptance Plan. The Acceptance Plan describes the roles, responsibilities, required resources, tasks, test cases and acceptance criteria required to determine the acceptability of the product.
The System Administrator needs to ensure that the infrastructure (hardware and software resources) and support software are ready for the upcoming test activities.
