What is decision table testing?

Decision table testing is a software testing design technique that focuses on verifying the decision-making logic of a system based on various conditions and inputs. This technique is particularly useful when the system behavior is determined by multiple combinations of inputs, allowing testers to create a clear representation of the different possible scenarios and their corresponding outputs.

By using decision tables, testers can systematically explore and validate the decision logic involved in the application. Each combination of conditions can represent a specific scenario, and the expected outcomes can be directly linked to these input combinations. This approach helps in identifying gaps in the specifications and ensures that all possible decision paths are tested.

When evaluating the nature of decision table testing, it's evident that its primary function is to assess how different inputs interact to result in specific decisions, making it closely related to the system requirements rather than solely focusing on structural or static aspects. Thus, the emphasis on verifying decisions aligns well with the role of decision table testing in ensuring that the software behaves as intended under various conditions.
