Scenario: A medical software application is being developed to assist doctors in diagnosing diseases. The system uses decision trees to recommend treatment options based on symptoms and patient history. What testing approach would be most effective for validating the decision-making logic of the application?

Decision Coverage Testing is effective for validating decision-making logic by ensuring that every decision point in the decision tree is exercised during testing. It provides insight into the completeness of testing, especially in complex scenarios like medical diagnosis where accurate decision-making is crucial.
