Acceptance testing can be said to be a technique of testing which is carried out to determine whether the software system has actually met the requirements specifications or not.
The major purpose why we carry out such a test is to help evaluate the compliance of the system with the business requirements as well as verifying or checking the desired criteria for delivery to the end-users have been met.
The major focus of acceptance testing is to check for the perspective of a business. Acceptance testing is performed in most cases to make sure that all the functional requirements are met by the product being made. This testing stage helps to carry out a verification process to ensure that the customers or clients receive their products having all the functional properties that are required.
