Configure the location of .coverage file when using /Enablecodecoverage in vstest.console.exe via command line

Question

Is there a way to set the location of where the .coverage file would be located if we set /Enablecodecoverage in vstest.console.exe?

I did not see an option in the command line call itself. Is it to be set in the .runsettings file?

Answer 1

As stated in General Command Line Options that /Enablecodecoverage uses default settings if setting file is not specified.

Yes, you have to customize your .runsettings file applies whenever you use Analyze Code Coverage.

• To customize run settings in a command line test

  • Launch the Visual Studio Developer Command Prompt:

    On Windows Start, choose All Programs, Microsoft Visual Studio, Visual Studio Tools, Developer Command Prompt.

  • Run:

    vstest.console.exe MyTestAssembly.dll /EnableCodeCoverage /Settings:CodeCoverage.runsettings
    

• To customize run settings in a build definition

  You can get code coverage data from a team build. Note: Make sure your .runsettings file is checked in.

Edit:

vstest.console.exe by default creates a *.coverage file, then the file can be converted to *.xml format.

To get the *.coverage file you can use the following command:

"c:\Program Files (x86)\Microsoft Visual Studio 11.0\Common7\IDE\CommonExtensions\Microsoft\TestWindow\vstest.console.exe" "PATH_OF_YOUR_EXECUTABLE_OR_DLL" /InIsolation /EnableCodeCoverage

Create a new command line project in Visual Studio and add a reference to C:\Program Files (x86)\Microsoft Visual Studio 11.0\Common7\IDE\PrivateAssemblies\Microsoft.VisualStudio.Coverage.Analysis.dll.

Add the following code (paths are hard coded here, but could be supplied as arguments):

using Microsoft.VisualStudio.Coverage.Analysis;

namespace CoverageConverter
{
    class Program
    {
        static void Main(string[] args)
        {
            using (CoverageInfo info = CoverageInfo.CreateFromFile(
                "PATH_OF_YOUR_*.coverage_FILE", 
                new string[] { @"DIRECTORY_OF_YOUR_DLL_OR_EXE"}, 
                new string[] { }))
            {
                CoverageDS data = info.BuildDataSet();
                data.WriteXml("converted.coveragexml");
            }
        }
    }
}

CodeCoverage.exe is another coverage tool to convert into *.xml format read more.

Edit 2:

You can use the /UseVsixExtensions option with /EnableCodeCoverage option to enable code coverage:

"C:\Program Files (x86)\Microsoft Visual Studio 11.0
 \Common7\IDE\CommonExtensions\Microsoft\TestWindow\vstest.console.exe"
 /UseVsixExtensions:true /EnableCodeCoverage "C:\Users\YourName\Documents\Visual Studio
 2012\Projects\YourProjectFolder\YourApp.Tests\bin\Debug\YourApp.Tests.dll"

Above command will generate the .coverage file under the directory TestResults.
