The concept of establishing pre-requisites (entrance criteria) and post conditions (exit criteria) an activity to be undertaken is extremely useful for managing any process, testing being no exception.

• Entrance criteria are those factors that must he present, at a minimum, to he able to start an activity. In Integration Testing for example, before a module can be integrated into a programme, it must he compiled cleanly and have successfully completed unit testing.If the entrance criteria of the next phase have been met, the next phase may be started even though the current phase is still under way, This is how overlapping schedules are allowed.
• Exit criteria are those factors that must be present to declare an activity completed. To proclaim System Testing completed, two criteria might be that all test cases must have been executed with a defined level of success (if other than 100%) and that there must be no more than a mutually agreed upon number of outstanding problems left unresolved. Exit criteria must be specifically expressed using terms such as, “X will be accepted if Y and a Z are completed.”
