Manual test execution trend sample report

  • Straipsnis

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

This article shows you how to get the execution state of one or more Test Plans in Power BI. The report generated is similar to following image and the Outcome trend chart of the Progress report.

The report displays a trend chart that summarizes the number and outcome states of Test Plans executed over a specified period of time.

  • Passed: Number of test cases passing.
  • Failed: Number of test cases failing.
  • NotApplicable: Number of test cases
  • Blocked: Number of test cases blocked from running.
  • NotExecuted: Number of test cases defined but not executed.

Questions the report answers

This report helps you track the team's progress with respect to planned testing of your product or service by answering the following questions:

  • How much testing is complete?
  • What is the current status of tests passing, failing, or being blocked?
  • How many tests are passing and what does the trend indicate about software quality?
  • How many tests are failing?
  • How many tests are blocked and what does the trend indicate?

A healthy test execution trend report shows a steady progress in test plans running and passing. Ideally, the report shows a relatively flat number of test cases for a given plan. As the development cycle progresses, the number of passing test cases should increase, and the numbers of test cases in other states should go down.

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.

For the report to generate useful data, the team must carry out the following activities to manage test plans:

  • Define test plans, test suites, and test cases. Specify their state. For a Test Suite to run, it must be in the In Progress state. For a Test Case to run, it must be in the Ready state. For details, see Create test plans and test suites and Create manual test cases.

  • Run manual tests and verify the results. Mark the results of each validation step in the test case as passed or failed. For details, see Run manual tests.

    Note

    Testers must mark a test step with a status if it is a validation test step. The overall result for a test reflects the status of all the test steps that were marked. Therefore, the test will have a status of failed if any test step is marked as failed or not marked.

Sample queries

You can use the following queries of the TestPointHistorySnapshot entity set to create different but similar test plan execution trend reports.

Note

To determine available properties for filter or report purposes, see Metadata reference for Test Plans Analytics. 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.

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.

let 
    Source = OData.Feed ("https://analytics.dev.azure.com/{organization}/{project}/_odata/v3.0-preview/TestPointHistorySnapshot?" 
        &"$apply=filter((TestSuite/TestPlanTitle eq '{testPlanTitle}') and (DateSK ge {startDate} and DateSK le {endDate}))" 
        &"/groupby(" 
            &"(DateSK)," 
            &"aggregate(" 
                &"$count as TotalCount," 
                &"cast(ResultOutcome  eq 'Passed', Edm.Int32) with sum as Passed," 
                &"cast(ResultOutcome  eq 'Failed', Edm.Int32) with sum as Failed," 
                &"cast(ResultOutcome eq 'Blocked', Edm.Int32) with sum as Blocked," 
                &"cast(ResultOutcome eq 'NotApplicable', Edm.Int32) with sum as NotApplicable," 
                &"cast(ResultOutcome eq 'None', Edm.Int32) with sum as NotExecuted," 
                &"cast(ResultOutcome ne 'None', Edm.Int32) with sum as Executed 
            ) 
        )", null, [Implementation="2.0"])

    Source

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, or omit "/{project}" entirely, for a cross-project query
  • {testPlanTitle} - Title of your test plan. Example: Fabrikam test plan.
  • {startDate} and {endDate} - Date range of interest. You can enter the dates in YYYYMMDD format. For example, 20220815 for 15 August 2022.

Query breakdown

The following table describes each part of the query.

Query part

Description

filter((TestSuite/TestPlanTitle eq '{testPlanTitle}'))

Return data for only selected test plan. You can add multiple plans with a clause like filter((TestSuite/TestPlanTitle eq '{testPlanTitle1}' or TestSuite/TestPlanTitle eq '{testPlanTitle2}')). You can also apply any other filters related to test suites and test configurations here.

and (DateSK ge {startDate} and DateSK le {endDate})

Date range of interest. You can enter the dates in YYYYMMDD format.

/groupby((DateSK)

Group the data into bins of same date. It produces one set of values per day in given date range.

/aggregate($count as TotalCount,

Aggregate data across the filtered test points with having count as TotalCount.

cast(LastResultOutcome eq 'Passed', Edm.Int32) with sum as Passed,

While aggregating, type-cast test points having latest execution outcome 'Passed' to 1 and sum them up as Passed metric.

(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.

Change column data type

From the Power Query Editor, select the TotalCount column and all other columns, and then select Data Type from the Transform menu, and choose Whole Number. For more information about changing the data type, see Transform Analytics data to generate Power BI reports, Transform a column data type.

(Optional) Rename column fields

You can rename column fields. For example, you can rename the column NotApplicable to Not Applicable, or TotalCount to Total Count. To learn how, see Rename column fields.

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 stacked area chart report

  1. In Power BI, under Visualizations, choose the Stacked area chart report. Screenshot of visualization fields selections for test plan execution trend run report.

  2. Drag and drop DateSK onto the X-Axis.

  3. Drag and drop Passed, Failed, Blocked, NotApplicable and NotExecuted onto the Y-Axis.

Your report should look similar to the following image.
