Acceptance test cases are based on what?

Acceptance test cases are fundamentally based on requirements because they are designed to ensure that the software meets the specified needs and expectations of the stakeholders. These requirements outline the functionality, features, and conditions that the product must fulfill in order to be considered acceptable for use. Acceptance criteria derived from these requirements guide the creation of test cases, providing a clear framework that can assess whether the software works as intended in real-world scenarios.

Ensuring alignment with requirements is critical because acceptance testing serves as a final check to validate that the delivered product aligns with the business objectives and user needs before it is officially released. This is why requirements form the cornerstone of acceptance test case development.
