Certification Description
The Certified Tester Model-Based Tester (CT-MBT) certification is a specialist-level credential offered by the International Software Testing Qualifications Board (ISTQB). It focuses on the principles and application of Model-Based Testing (MBT), a modern approach to software testing that leverages system models to automatically or semi-automatically generate test cases. Instead of designing individual tests manually, testers use models to represent the expected behavior of a system under test (SUT), allowing for better visualization, traceability, and consistency throughout the testing lifecycle.
This certification equips professionals with the knowledge and skills required to create test models using a variety of modeling languages and notations, such as UML, state charts, decision tables, and control flow graphs. These models form the basis for generating structured and optimized test cases that reflect real-world scenarios and business logic. CT-MBT emphasizes the strategic integration of model-based techniques into existing testing processes and tools. Candidates also learn how to evaluate model quality, maintain model-test alignment as systems evolve, and align MBT with methodologies like Agile, DevOps, and continuous integration/continuous delivery (CI/CD).
