Microsoft DevOps Engineer Expert AZ-400 Practice Question
You are creating a Power BI dashboard that must display a daily trend of passed versus failed automated tests for each Azure DevOps pipeline during the last 90 days. You will query the Azure DevOps Analytics OData feed (v3). To minimise query complexity and avoid aggregating millions of individual test-result rows, which entity set should you query?
The TestResultsDaily entity set is a pre-aggregated, time-series view produced by the Analytics service. Each record already contains the count of passed, failed, not executed, and other outcomes for a pipeline on a given date. Using this entity eliminates the need to join TestRuns to raw TestResults or perform manual grouping, while still providing historical accuracy. The TestResults, TestRuns, and Builds entity sets store detailed or unrelated data that would require additional joins and calculations to achieve the same daily trend.
