Note
System Testing: The process of testing an integrated system to verify that it meets specified requirements is known as system testing.
Acceptance Testing: After the system testing is over, the software/application is tested by the client/user to check whether it meets the requirements given by him or not. This is known as acceptance testing.
Acceptance testing can be performed either at the developer's site (premises) or client site.
