Which type of test verifies whether a program meets its initial requirements?

The acceptance test is designed to determine whether a program meets its specified requirements and is ready for deployment in a live environment. This type of testing typically involves the end users or stakeholders assessing the software against their initial requirements and expectations. It is often the final phase of testing before the software is released, confirming that it performs as intended in real-world scenarios.

While functionality tests do examine whether individual components of the software function correctly, acceptance testing is broader and includes validating that the overall system meets the agreed-upon specifications from the start. Thus, it plays a critical role in ensuring that the software is fit for purpose and satisfies the needs of its users.
