What is the difference between functional testing and acceptance testing?

Functional testing is a type of testing that focuses on verifying the individual functions or features of a software application to ensure they work correctly. It is performed by testers and aims to identify any defects or issues in the functionality of the software.

On the other hand, acceptance testing is a type of testing that is performed to determine whether a software application meets the requirements and expectations of the end-users or stakeholders. It is usually conducted by the end-users or a designated group of individuals who represent the end-users. The main goal of acceptance testing is to validate that the software meets the specified business requirements and is ready for deployment.

In summary, the main difference between functional testing and acceptance testing lies in their objectives and the parties involved. Functional testing focuses on verifying the functionality of the software, while acceptance testing focuses on validating whether the software meets the requirements and expectations of the end-users.
