To ensure every row in a decision tree can be evaluated regardless of input values, what testing method should be used?

The testing method that ensures every row in a decision tree can be evaluated, regardless of input values, involves adding the decision tree to a decision shape with test cases. This approach allows for systematic evaluation of each path in the decision tree. By incorporating test cases, you can simulate various scenarios and inputs, ensuring that all decision paths are exercised. This is crucial for validating the decision logic and confirming that the tree behaves as expected across different situations.

Using test cases within a decision shape helps to capture all possible outcomes and ensures that the logic for each decision rule is functioning correctly. This method provides comprehensive coverage, as it checks the decision tree against various conditions, demonstrating how it handles different inputs and confirming its robustness. It is an effective way to validate that every row can be evaluated and that the overall decision-making process aligns with the expected business rules.
