TFS 2010 SP1 Goody: Using the API to retrieve Code Coverage Information for a Build

There was a new approach for exposing Test related information in TFS 2010 in the API thru the new TestManagementService.  It was particularly easy to get the Unit Test information for a give build URI:

        using (TfsTeamProjectCollection Tfs = new TfsTeamProjectCollection(…)
        {
            Uri myBuild= new Uri(… some build URI…);
            TestManagementService tcm = (TestManagementService) Tfs.GetService<TestManagementService>();

            ITestManagementTeamProject teamProject = tcm.GetTeamProject(… Team Project Name…);

            foreach (var testResult in teamProject .TestRuns.ByBuild(myBuild))
            {
                testResult.Statistics.CompletedTests;
               
            }
        }

With SP1 of Visual Studio and the Team Client, Code Coverage results by build or test run has been exposed as the CoverageAnalysisManager property off ITestManagementTeamProject.

namespace Microsoft.TeamFoundation.TestManagement.Client
{
    public interface ICoverageAnalysisManager
    {
        IBuildCoverage[] QueryBuildCoverage(string buildUri, CoverageQueryFlags flags);
        ITestRunCoverage[] QueryTestRunCoverage(int testRunId, CoverageQueryFlags flags); 
    }
}

So now, if you want extend the example above to iterate thru the Assembly (Module)level Code Coverage information:

foreach (IBuildCoverage coverage in teamProject.CoverageAnalysisManager.QueryBuildCoverage(myBuild.ToString(), CoverageQueryFlags.Modules))
{
    foreach (IModuleCoverage moduleInfo in coverage.Modules)
    {
        moduleInfo.Name;
        moduleInfo.Statistics.BlocksCovered;
        moduleInfo.Statistics.BlocksNotCovered;
        moduleInfo.Statistics.LinesCovered;
        moduleInfo.Statistics.LinesNotCovered;
        moduleInfo.Statistics.LinesPartiallyCovered;
    }
}

MVCConf Materials: Industrial Strength NuGet

Want to again shout out to The Hex, Eric Hexter,  for getting me involved, coordinating, guiding, all that good stuff .  And thank you those that attended.

Link to the basic materials –> (http://tinyurl.com/4m7exyo)

1. Build.zip:  The AndyWahr.NuGet.sln contains the BuildHelpers (custom workflow assemblies), the BuildTemplate project (for visual editing of the build Workflow), and NuGet-Project (nuget package for creating nuget’s).
2. Widgets.com.zip:  Simulated project of a consumer of a NuGet.
3. Widgets..Framework.zip:  Simulated solution of a Framework team that produces a NuGet for other teams.
4. Industrial Strength Nuget.pptx:  Deck for the presentation.

I’ll be posting over the next little bit full details that went into the demo:

1. Setup of the environment
2. Detail view of the custom workflow
3. More info about the process.

Stay Tuned!
