  What Is Model-Based Testing and How Does It Improve Test Coverage?

  Posted by Sophie on February 4, 2026 at 10:14 pm

  Model-based testing (MBT) is a software testing technique where test cases are automatically generated from models that represent the expected behavior of a system. Instead of writing individual test cases manually, teams create abstract models—such as state diagrams, flow charts, or decision tables—that describe how the application should behave under different conditions.

  The key advantage of model based testing is its ability to improve test coverage systematically. Since tests are derived from a model, MBT can explore multiple paths, edge cases, and state transitions that might be missed in traditional test design. This makes it especially effective for complex systems with many workflows, rules, or user interactions.

  Model-based testing also enhances consistency and maintainability. When requirements change, updating the model automatically updates the generated test cases, reducing manual effort and minimizing gaps between specifications and tests. This tight alignment helps teams detect defects earlier and ensures the system behaves according to its defined logic.

  In practice, model-based testing works best alongside other testing approaches. While exploratory and regression testing validate real-world usage, MBT provides a structured, requirements-driven view of system behavior. Together, they help teams achieve higher confidence in software quality while keeping testing efficient and scalable.
