Failed tests sample report

  • Artikkel

Azure DevOps Services | Azure DevOps Server 2022 | Azure DevOps Server 2020

You can create a report that lists failed tests, similar to the following image, for pipeline runs that include test tasks. For information on adding tests to a pipeline, see the Test task resources section later in this article.

Screenshot of Failed Tests Table report.

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

  • Failed tests for build workflow
  • Failed tests for release workflow
  • Failed tests for a particular branch
  • Failed tests for a particular test file
  • Failed tests 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

Note

This article assumes you 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 pipeline failed test 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. For more information about the data type of each value, review the metadata provided for the corresponding EntityType.

Failed tests for a Build workflow

Use the following queries to view the failed tests for a Build workflow pipeline.

Copy and paste the following Power BI query directly into the Get Data > Blank Query window. For more information, see Overview of sample reports using OData queries.

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.

(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, PassedCount, FailedCount, NotExecutedCount, NotImpactedCount, and FlakyCount columns; select Data Type from the Transform menu; and then choose Whole Number.

  2. Select the PassRate column; 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.

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 Failed tests table report.

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

    • Test.TestName
    • TotalCount
    • PassedCount
    • FailedCount
    • NotImpactedCount
    • NotExecutedCount
    • FlakyCount
    • PassRate

Your report should look similar to the following image.
