What does the DMN Test Lab perform? Note: There are 3 correct answers to this question.

Question

Options

• AValidates that diagrams are consistent
• BConnects to SAP Signavio Process Goverance
• CChecks expected results against calculated results
• DLinks to BPMN diagrams
• EKeeps track of previous tests for comparison

• A
  84% (26)
• B
  10% (3)
• D
  6% (2)

Explanation

DMN Test Lab is a testing feature within DMN tools (such as SAP Signavio) that focuses specifically on validating decision logic. A is correct because the Test Lab checks that decision tables and diagrams are internally consistent - for example, detecting overlapping or missing rules. C is correct because its core function is running test cases and comparing your expected output values against what the decision model actually calculates, confirming the logic works as designed. E is correct because the Test Lab maintains a history of prior test runs, allowing you to compare results over time and detect regressions when rules change.

B is wrong because connecting to SAP Signavio Process Governance is a separate integration feature, not a Test Lab function. D is wrong because linking DMN decisions to BPMN diagrams is a modeling/collaboration feature, not something the Test Lab itself performs.

Memory tip: Think of the Test Lab with the acronym CVH - Consistency, Verification, History. Any test lab worth its name must check that things are consistent, verify outputs match expectations, and keep a history - those map directly to A, C, and E.
