Code Coverage Excel Report

With the Code Coverage report, you can monitor how much code the team is testing over time. Team members can use this report to help determine how close parts of the code are to release quality. For information about how to access this report, see Excel Reports (Agile).


You can view the Code Coverage report from the Quality dashboard. You can access this dashboard only if your team project portal has been enabled and is provisioned to use Microsoft Office SharePoint Server 2007. For more information, see Access a Team Project Portal and Process Guidance.

Data in the Report

The team can review the Code Coverage report to determine whether tests cover the code sufficiently and how the coverage changed over time. As the following illustration shows, the report provides a line graph of the build verification test (BVT) code coverage and other coverage over the most recent four weeks.

Code Coverage Report

This report is based on a PivotChart report that shows the most recent four weeks of data that was captured for code changes and that is stored in the data warehouse.

Required Activities for Tracking Code Coverage

For the Code Coverage report to be useful and accurate, team members must perform the following activities:

Interpreting the Report

If the team practices test-driven development or similar techniques, the code coverage should almost always approach 100%. If unit tests are reused as BVTs, the code coverage should be visible in the Code Coverage report.

You can review the Code Coverage report to answer these questions:

  • How much of the code is the team testing?

  • Does the team have sufficient code coverage?

  • Is code coverage increasing or decreasing over time?

For more information about how code coverage impacts quality, see Quality Dashboard (Agile) and Build Quality Indicators Report.

Customizing the Report

You can customize the Code Coverage report by opening it in Office Excel and changing the filter options or a column field list for the PivotTable report. You can modify the report to support other views, as the following table describes.



Code coverage for an iteration

Change the filter for Iteration (default=All)

Code coverage for a product area

Change the filter for Area (default=All)

Code coverage for the most recent six, eight, or more weeks

In the Columns PivotTable Field List, replace @@Last 4 weeks@@ with a different Set

For more information about how to work with and customize PivotTable and PivotChart reports, see the following pages on the Microsoft Web site:
