Power BI AI DAX Measure Test Harness

Use this skill to make DAX expert replacement verifiable.

Test Areas

• KPI contract to DAX measure mapping.
• Expected value tests for known slices.
• Reconciliation totals against source systems.
• Date-basis tests for order, invoice, delivery, posting, or fiscal dates.
• Filter context tests for customer, product, plant, warehouse, region, and owner.
• Regression tests against previous measure outputs.

Output Requirements

• Include DAX query, expected value, tolerance, test data scope, owner, and pass/fail criteria.
• Mark measures without test evidence as certification risks.
