Verification and Validation

Ensure that the deliverable meets business and customer requirements.

In Acceptance Testing, conditions that must be met to satisfy the customer (called Acceptance Criteria) are expressed as an example or usage scenario - called the Acceptance Test. These statements are written from the customer's point of view and explain how a user story or feature should work. In order for the story or feature to be accepted it needs to pass the acceptance criteria; otherwise, it fails. Many times, acceptance tests are automated so they can be performed on all versions of the software. Acceptance criteria usually include one or more acceptance tests.
