Abstract
Model-Based Systems Engineering (MBSE) using CATIA Magic Systems of Systems Architect (formerly known as CAMEO) is applied to develop a structured and traceable approach to test case modeling for CubeSat missions. The effort focuses on supporting unit-, subsystem-, and system-level testing by explicitly linking system requirements to corresponding test cases within the model, ensuring clear traceability across all verification levels. Each test case is organized within a dedicated package that includes a Block Definition Diagram (BDD) and Internal Block Diagram (IBD) to represent the complete test configuration, capturing all relevant components, subsystem boundaries, and interface connections involved in the test setup. In addition to the structural representation, system behavior during test execution is modeled using activity diagrams to define operational flow and decision logic, as well as state machine diagrams to capture system states and transitions throughout the test. Although a traditional written test plan exists, modeling the test cases within an MBSE environment provides added value by creating a consistent and visual representation of the test logic, improving communication across subsystem teams, and enabling early identification of gaps or inconsistencies between requirements, architecture, and verification procedures. This approach demonstrates a more rigorous and integrated method for managing verification in CubeSat systems.
