Offline Mbt
Offline Model-Based Testing (Offline MBT) generates test cases from a model before test execution begins.
“Model-based test approach whereby test cases are generated into a repository for future execution.”

View the complete ISTQB GlossaryWhat is Offline Mbt?
Generated tests are reviewed, stored, and executed later using manual or automated testing approaches.
Separate phases: Test generation and execution occur independently.
Review opportunity: Generated tests can be inspected before execution.
Automation support: Generated scripts may be exported to automation tools.
Real World Example
A regulated product team is preparing a release where Offline mbt appears in reviews, test design conversations, or defect triage rather than as an isolated glossary word.
The risk is that the team treats Offline mbt as interchangeable with nearby ISTQB terms. That makes test scope blurry and can lead to weak evidence for the release decision.
The tester anchors the discussion in the official definition, asks where the concept appears in the product, and designs examples that show the difference between Offline mbt and similar ideas.
The page becomes useful in practice because Offline mbt is connected to a specific testing decision, not memorized as a detached definition.
