When is it performed?

Acceptance Testing is the fourth and last level of software testing performed after System Testing and before making the system available for actual use.

Who performs it?

  • Internal Acceptance Testing (Also known as Alpha Testing) is performed by members of the organization that developed the software but who are not directly involved in the project (Development or Testing). Usually, it is the members of Product Management, Sales and/or Customer Support.
  • External Acceptance Testing is performed by people who are not employees of the organization that developed the software.
    • Customer Acceptance Testing is performed by the customers of the organization that developed the software. They are the ones who asked the organization to develop the software. [This is in the case of the software not being owned by the organization that developed it.]
    • User Acceptance Testing (Also known as Beta Testing) is performed by the end users of the software. They can be the customers themselves or the customers’ customers.
