requirements analysis

Acceptance testing

includes all the preparations for the series of tests to be performed on the system.

tests the functioning of the system as a whole in order to determine if discrete modules will function together as planned.

tests each program separately.

provides the final certification that the system is ready to be used in a production setting.
