Testability
Degree 2 which a system or component facilitates the establishment of test criteria and the performance of tests, system or component facilitates the establishment of test criteria and the performance to tests to determine whether those criteria have been met, requirement is stated in terms that permit establishment of test criteria and performance of tests to determine whether those criteria have been met. |
