Validating a test
Validated test cases and systems are essential in ensuring that products – undergoing tests – conform to their respective test specifications.
This is especially important during conformity assessment procedures.
Questionnaire Validation in a Nutshell (I strongly recommend running PCA and CA again after completing the formal data collection phase [i.e., after you use your questionnaire to collect “real” data].
You want to make sure that you get the same factor loading patterns.) When reporting the results of your study you can claim that you used a questionnaire whose face validity was established experts.
Level 2: The tests are executed on one test platform against at least one System Under Test (SUT). Optionally, a back-to-back validation (mirror test cases) and/or a data-driven codec validation are performed.
The following definitions of validation levels for standardized TTCN-3 test specifications have been developed by the ETSI Centre for Testing and Interoperability (CTI).
Test Suites, however, cannot easily be validated by means of a design review as they are written in TTCN-3 or some other programming language.
