What is the primary focus of acceptance testing?

Acceptance testing primarily focuses on verifying that the software meets the agreed-upon requirements and is ready for use by the end user or customer. This type of testing is often performed in the final phase of development and is critical in determining whether the software is fit for release. It emphasizes ensuring that the functionality aligns with the business needs and requirements specified at the project's outset.

While the verification of requirements is significant, the other areas, such as performance under load, security vulnerabilities, and integration with other systems, may be evaluated during different testing phases like performance testing, security testing, or integration testing. Acceptance testing is specifically centered on end-user needs and satisfaction, ensuring that the final product complies with the specified criteria and can be confidently delivered to users.
