Requirements tracking sample report

  • Artikkeli

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

You can track the quality of work items that belong to the Requirements category with the requirements tracking report. The Requirements category includes work items such as User Stories (Agile), Product Backlog Items (Scrum), Issues (Basic), and Requirements (CMMI). For more information about work item categories, see Track user stories, issues, bugs, and other work items.

The following image shows an example of a requirements tracking report.

This report displays the following information for each requirement that it lists:

  • Percent work completed: Progress bar that shows the percentage of completed work based on the rollup of completed hours for all tasks that are linked to the requirement.
  • Passed tests: The number of test cases run that's passed based on the most recent test run.
  • Failed tests: The number of test cases run that's failed based on the most recent test run.
  • Run tests: The number of test runs that's executed.
  • Active bugs: The number of linked bugs in an Active state.
  • Closed bugs: The number of linked bugs in a Closed, Done, or Completed state.

Note

Requirement tracking is supported only for test cases linked through a Requirement-based test suite. The association between a requirement work item—User Story (Agile), Product Backlog Item (Scrum), Requirement (CMMI), or Issue (Basic)—and manual test execution is only formed when the test case is linked via a Requirement-based test suite.

Questions the report answers

Requirements tracking reports are useful for answering the following types of questions.

Work progress

  • Does the amount of work that remains for each requirement correspond to your expectations?
  • Are top-ranked requirements being implemented first?
  • How many tests are defined for each requirement? How many tests are passing?
  • What requirements are being implemented that have no test cases defined for them?

Quality progress

  • How many test cases have run for each requirement, and how many have passed?
  • How many active bugs does each requirement have?
  • Are bugs being found for requirements that are being tested?
  • Are bugs being resolved or are they remaining active?

Risk assessment

  • Which requirements are at risk?
  • Which requirements aren't sufficiently stable for release?
  • Which requirements can we ship today?

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, you need to have performed the following tasks:

  • You've define requirement work items and assigned them to the area and iteration paths of interest. For information about how to define area and iteration paths, see Define area paths and Define iteration paths.
  • To get the percentage of hours completion, you need to fill in the Complete Work and Remaining Work fields of tasks or bugs linked to requirements with the Child link type.
  • To get the execution status of test cases, you will have created requirement-based test suites in Test Plans corresponding to those requirements. Inline tests you add through the board satisfy this prerequisite, however requirements that you link to tests don't. For more information, see Create test plans and test suites.
  • To get the status of bugs, you will have created and linked bugs to requirements with the Child link type.

Sample queries

To generate the report, you must add three Power BI queries to Power BI desktop and then link them. Each query executes either the WorkItems or TestPoints entity set.

Note

The Power BI query snippets provided in the following sections include the requisite data transforms to expand columns and change data type.

Note

To determine available properties for filter or report purposes, see Metadata reference for Azure Boards. 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.

Query area and iteration paths

In order to scope your report to a particular Area and Iteration path, you can filter the query using AreaSK and IterationSK. For details, see Define basic queries using OData Analytics.

Query for percentage of hours completion for requirements

Note

The following query works for the Agile process since it defines Remaining Work and Completed Work fields in work items.

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/WorkItems?

Query for test execution status of requirements

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.

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} - The name of your project
  • {iterationSK} - The GUID associated with the Iteration Path of interest. To look up the GUID, see [../extend-analytics/wit-analytics.md#iterationsk](Return the IterationSK for a specific Iteration Path)
  • {areaSK} - The GUID associated with the Area Path of interest. To look up the GUID, see [../extend-analytics/wit-analytics.md#areask](Return the AreaSK for a specific Area Path).

Query breakdown

The following table describes each part of the query.

Query part

Description

$filter=( IterationSK eq {iterationSK} and AreaSK eq {areaSK} )`

Returns data for only selected Iteration, Area, and backlog work items.

Processes/any(p:p/BacklogType eq 'RequirementBacklog')

Filter the work items in such a way that they should fall in 'requirements' category for at least one process associated with them.

Processes/all(p:p/IsBugType eq false)

Omit the bug type work items while getting requirements. In Basic process template, Issue work items are also of bug type, so for Basic process remove this clause from your query.

filter( (TestSuite/RequirementWorkItem/IterationSK eq {iterationSK} and TestSuite/RequirementWorkItem/AreaSK eq {areaSK} and TestSuite/RequirementWorkItem/Processes/any(p:p/BacklogType eq 'RequirementBacklog') and TestSuite/RequirementWorkItem/Processes/all(p:p/IsBugType eq false) ) )

Return data for only selected requirements based on Iteration and Area.

/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.

&$expand=Descendants( $apply=filter( CompletedWork ne null or RemainingWork ne null )

Returns Completed Work and Remaining Work data for child work items of filtered parent items.

/aggregate( iif(CompletedWork ne null, CompletedWork, 0) with sum as SumCompletedWork, iif(RemainingWork ne null, RemainingWork, 0) with sum as SumRemainingWork

Aggregate Completed Work and Remaining Work data across the filtered work items.

)/compute( (SumCompletedWork add SumRemainingWork) as TotalWork, SumCompletedWork as SumCompleted

Compute the total rollup of Completed Work and Remaining Work.

)/compute( iif(TotalWork gt 0,(SumCompleted div cast(TotalWork, Edm.Double) mul 100), 0) as PercCompletedWork )

Calculate the percent of completed wor.

Create the Table report

To create the report, perform the following steps:

  1. From the Modeling tab, choose Manage Relationships and link the three query results by WorkItemId column.
  2. Under Visualizations, choose Table.
  3. Add the columns you're interested in from the three Power BI queries.
  4. Select Sum as aggregation for additive columns like Passed tests etc.

    Power BI select Sum as aggregation

Your report should look similar to the following image.
