Test duration sample report

[!INCLUDE version-gt-eq-2020]

Test duration reports, similar to the one shown in the following image, provide insight into the number of times a test is run and the average time it takes for a particular test to execute during a pipeline run.

:::image type="content" source="media/pipeline-test-reports/test-duration-table-report.png" alt-text="Screenshot of Test Duration Table report.":::

Use the queries provided in this article to generate the following reports:

  • Test duration for build workflow
  • Test duration for release workflow
  • Test duration for a particular branch
  • Test duration for a particular test file
  • Test duration for a particular test owner

Sample queries

You can use the following queries of the TestResultsDaily entity set to create different but similar test duration reports. The TestResultsDaily entity set provides a daily snapshot aggregate of TestResult executions, grouped by test.

[!INCLUDE temp]

Test duration for Build workflow

Use the following queries to view the test duration report for a pipeline with a Build workflow.

Power BI query

[!INCLUDE temp]

Test duration filtered by branch

To view the test duration of pipeline tests for a particular branch, use the following queries. To create the report, carry out the following extra steps along with what is specified later in this article.

  • Expand Branch into Branch.BranchName
  • Select Power BI Visualization Slicer and add the field Branch.BranchName to the slicer's Field
  • Select the branch name from the slicer for which you need to see the outcome summary.

For more information about using slicers, see Slicers in Power BI.

Expand the Test column in Power BI

Expand the Test column to show the expanded entity Test.TestName. Expanding the column flattens the record into specific fields. To learn how, see Transform Analytics data to generate Power BI reports, Expand columns.

Change column data type

  1. From the Power Query Editor, select the TotalCount column; select Data Type from the Transform menu; and then choose Whole Number.

  2. Select the TotalDuration and AvgDuration columns; select Data Type from the Transform menu; and then choose Decimal Number.

For more information about changing the data type, see Transform Analytics data to generate Power BI reports, Transform a column data type.

[!INCLUDE temp]

Create the Table report

  1. In Power BI, under Visualizations, choose **Table, and drag and drop the fields onto the Columns area.

    :::image type="content" source="media/pipeline-test-reports/visualizations-test-duration-table.png" alt-text="Screenshot of visualization fields selections for Test Duration table report. ":::

  2. Add the following fields to the Columns section in the order listed.

    • Test.TestName
    • TotalCount
    • AvgDuration

  3. Right select the AvgDuration and choose Average instead of Sum.

Your report should look similar to the following image.
