Which testing type is focused on demonstrating compliance with requirements and specifications?

The type of testing focused on demonstrating compliance with requirements and specifications is acceptance testing. Acceptance testing is conducted to determine whether the software meets the acceptance criteria set forth by the stakeholders, such as the end users or clients. It is the final phase of testing and validates that the delivered product matches the specified requirements and is ready for deployment.

This testing type typically includes both functional and non-functional requirements, ensuring that the product behaves as expected in a real-world environment. The goal is to confirm that the software satisfies all specified requirements and is fit for use in its intended context.

In summary, acceptance testing is essential for providing stakeholders with confidence that the software product is compliant with their requirements and can be positioned for release.
