ENTRY & EXIT CRITERIA FOR TESTING

As the name implies Entry criteria denotes the conditions or process that must be present before a process can begin. For example Test Plan, Test Strategy, Test tools are some of the Entry criteria for carrying out the testing process. Exit criteria as the name implies denotes the conditions or process that must be present before a cycle completes. Test results or Test Summary Report, Test Logs are some of the Exit criteria out of the testing process.


The Entrance Criteria specified by the system test controller, should be fulfilled before System Test can commence. In the event, that any criterion has not been achieved, the System Test may commence if Business Team and Test Controller are in full agreement that the risk is manageable.

* All developed code must be unit tested. Unit and Link Testing must be completed and signed off by development team.
* System Test plans must be signed off by Business Analyst and Test Controller.
* All human resources must be assigned and in place.
* All test hardware and environments must be in place, and free for System test use.
* The Acceptance Tests must be completed, with a pass rate of not less than 80%.

The Exit Criteria detailed below must be achieved before the Phase 1 software can be recommended for promotion to Operations Acceptance status. Furthermore, I recommend that there be a minimum 2 days effort Final Integration testing AFTER the final fix/change has been retested.

* All High Priority errors from System Test must be fixed and tested
* If any medium or low-priority errors are outstanding - the implementation risk must be signed off as acceptable by Business Analyst
* Project Integration Test must be signed off by Test Controller and Business Analyst.
* Business Acceptance Test must be signed off by Business Expert.

FURPS


FURPS is an acronym representing a model for classifying software quality attributes (Functional & Non-functional):
  • Functionality - Feature set, Capabilities, Generality, Security
  • Usability- Human factors, Aesthetics, Consistency, Documentation
  • Reliability - Frequency/severity of failure, Recoverability, Predictability, Accuracy, Mean time to failure
  • Performance - Speed, Efficiency, Resource consumption, Throughput, Response time
  • Supportability - Testability, Extensibility, Adaptability, Maintainability, Compatibility, Configurability, Serviceability, Installability, Localizability, Portability
The model, developed at HP, was first publicly elaborated by Grady and Caswell. The + was later added to the model after various campaigns at HP to extend the acronym to emphasize various attributes.
FURPS+ is now widely used in the software industry.
