Test duration sample report

  • Article

Azure DevOps Services | Azure DevOps Server 2022 | Azure DevOps Server 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. For information on adding tests to a pipeline, see the Test task resources section later in this article.

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

Important

Power BI integration and access to the OData feed of the Analytics Service are generally available for Azure DevOps Services and Azure DevOps Server 2020 and later versions. The sample queries provided in this article are valid only against Azure DevOps Server 2020 and later versions, and depend on v3.0-preview or later version. We encourage you to use these queries and provide us feedback.

Prerequisites

  • To view Analytics data and query the service, you need to be a member of a project with Basic access or greater. By default, all project members are granted permissions to query Analytics and define Analytics views.
  • To learn about other prerequisites regarding service and feature enablement and general data tracking activities, see Permissions and prerequisites to access Analytics.

Note

This article assumes you've read Overview of Sample Reports using OData Queries and have a basic understanding of Power BI.

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.

Note

To determine available properties for filter or report purposes, see Metadata reference for Test Plans Analytics and Metadata reference for Azure Pipelines. You can filter your queries or return properties using any of the Property values under an EntityType or NavigationPropertyBinding Path values available with an EntitySet. Each EntitySet corresponds to an EntityType. To learn more about the data type of each value, review the metadata provided for the corresponding EntityType.

Substitution strings and query breakdown

Substitute the following strings with your values. Don't include brackets {} with your substitution. For example if your organization name is "Fabrikam", replace {organization} with Fabrikam, not {Fabrikam}.

  • {organization} - Your organization name
  • {project} - Your team project name
  • {pipelinename} - Your pipeline name. Example: Fabrikam hourly build pipeline
  • {startdate} - The date to start your report. Format: YYYY-MM-DDZ. Example: 2021-09-01Z represents September 1, 2021. Don't enclose in quotes or brackets and use two digits for both, month and date.

Query breakdown

The following table describes each part of the query.

Query part

(Optional) Rename query

You can rename the default query label, Query1, to something more meaningful. Simply enter a new name from the Query Settings pane.

Screenshot of Power BI query menu options, rename query.

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.

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

Close the query and apply your changes

Once you've completed all your data transformations, choose Close & Apply from the Home menu to save the query and return to the Report tab in Power BI.

Screenshot of Power Query Editor Close and Apply option.

Create the Table report

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

    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 click the AvgDuration and choose Average instead of Sum.

Your report should look similar to the following image.
