Model-Based testing in MBSE: Patterns, Practices, and Pathways to Reuse

In today’s engineering environment, systems are more interconnected, safety-critical, and fast-evolving than ever. Traditional testing methods are no longer enough, and Model-Based testing (MBT) within Model-Based Systems Engineering (MBSE) is becoming a necessity. By deriving tests directly from system models, MBT ensures earlier defect detection, greater traceability, and the agility to adapt to rapid design changes without sacrificing quality.

During this presentation we will address the now or never moment for MBT adoption and explore proven patterns for integrating MBT into MBSE workflows, techniques for extending it into invariant checking, and strategies for maintaining and reusing test cases as enduring engineering assets.

Attendees will leave with a clear understanding of how MBT can accelerate innovation, reduce lifecycle costs, and deliver resilient systems in a world where speed and precision define competitive advantage.

• Recognize why MBT is essential in the face of growing system complexity and compressed development cycles.

• Learn repeatable patterns for test design, execution, and automation in an MBSE context.

• Understand how invariant checking helps ensuring that critical system properties hold during all test executions and how test automation can safeguard against regression and design drift.

• Discover modernization approaches for reusing tests across programs, platforms, and generations of products.

• Apply MBT in a vendor-agnostic way to fit diverse organizational needs.
