[[Model checking|Model checkers]] can also be used for test case generation.<ref>Gordon Fraser, Franz Wotawa, and Paul E. Ammann. Testing with model checkers: a survey.

When used for testing, a model of the system under test, and a property to test is provided to the model checker. Within the procedure of proofing, if this property is valid in the model, the model checker detects witnesses and counterexamples. A witness is a path where the property is satisfied, whereas a counterexample is a path in the execution of the model where the property is violated. These paths can again be used as test cases.
