These analyses and predictions are based on parameterized performance specifications. However, the quality of the specifications and their trustworthiness usually remain unspecified. In existing approaches, it remains unclear if a specification can be reused in another context and which effect its use may have on the quality of the analysis or prediction. In this paper, we propose a test-based approach to validate parameterized performance specifications against deployed component implementations. The validation is used to certify the quality and valid parameter ranges of the specifications.enText/Conference Paper1617-5468
