Verification and Validation Test Framework Using a Model‐Based Systems Engineering Approach

Abstract

AbstractThis paper describes a test framework for verification and validation (V&V) planning and execution using a model‐based system engineering (MBSE) approach that is suitable for large‐scale cyber‐physical systems. The test framework (TF) is defined using the systems modeling language (SysML) and an MBSE tool and describes and links to external test plans, test procedures, and other relevant test documents. This test framework approach includes the following considerations: level of abstraction of systems for testing, multiple types of testing across the development lifecycle, design vs. system V&V approaches, verification vs. validation, and the use of test patterns, instances, inheritance, and libraries. The libraries contain distinct types of tests to maximize model element reuse. An example is provided that illustrates the application of this V&V Test Framework (V&VTF) to a lubrication system. This method demonstrates that the proposed V&VTF is desirable as part of Systems Engineering metamorphosis to support an organization's digital transformation.
