Päätöstaulukotestin

Päätöstaulukotestin, also known as Decision Table Testing, is a software testing technique used to design test cases based on the conditions and actions described in a decision table. This method is particularly effective for systems with complex business logic, where multiple input conditions can lead to various outcomes.

The core of decision table testing involves creating a table that systematically lists all possible combinations of input conditions and the corresponding actions or outputs. The table typically has rows representing conditions and columns representing specific combinations of those conditions, along with the actions that should be taken for each combination. Each column represents a unique scenario.

The process begins by identifying all relevant input conditions and their possible values. Then, the actions or outputs that result from different combinations of these conditions are determined. Finally, a decision table is constructed, ensuring that every possible combination of conditions is covered. Test cases are then derived directly from each column of the table, providing a clear and exhaustive set of tests.

Decision table testing helps to identify missing logic, incomplete rules, and ambiguities in requirements. It ensures that all combinations of conditions are considered, leading to more thorough test coverage and a higher quality software product. This technique is valuable for testing business rules, complex workflows, and scenarios where multiple factors influence system behavior.
