visual studio 2010 - Running VS2010 UnitTests project from TFS2008 Team Build

Question

I have a Visual Studio 2010 MVC 3 application with unit tests projects in it. I have a TFS 2008 build definition to build the solution.

On the build agent i have got following installed

• VS2008 team system developer edition
• VS2010 Professional installed
• I have updated the msbuildpath in the tfsservice.exe.config to .NET 4 farmework
• Deleted all the workspaces
• Have followed all the steps at http://blog.aggregatedintelligence.com/2011/03/vs2010-tfs-2008-and-unit-tests.html

But when i run the build I get the following error:-

Using "TestToolsTask" task from assembly "c:Program FilesMicrosoft Visual Studio 10.0Common7IDEPrivateAssembliesMicrosoft.TeamFoundation.Build.ProcessComponents.dll".
    Task "TestToolsTask"
      C:Program FilesMicrosoft Visual Studio 10.0Common7IDEMSTest.exe /nologo /usestderr /searchpathroot:"c:TFSCoreCrimeBinariesRelease" /resultsfileroot:"c:TFSCoreCrimeTestResults" /testcontainer:"c:TFSCoreCrimeBinariesRelease\Project1.UnitTests.dll" /testcontainer:"c:TFSCoreCrimeBinariesRelease\Project2.UnitTests.dll" /testcontainer:"c:TFSCoreCrimeBinariesRelease\Project3.UnitTests.dll" /testcontainer:"c:TFSCoreCrimeBinariesRelease\Project4.UnitTests.dll" /publish:"http://server:8080/" /publishbuild:"vstfs:///Build/Build/88124" /teamproject:"Core" /platform:"Any CPU" /flavor:"Release" 
      Invalid switch "/publish".
      Invalid switch "/publishbuild".
      Invalid switch "/teamproject".
      Invalid switch "/platform".
      Invalid switch "/flavor".
      For switch syntax, type "MSTest /help"
    C:Program FilesMSBuildMicrosoftVisualStudioTeamBuildMicrosoft.TeamFoundation.Build.targets(1406,5,1406,5): warning : TF270015: 'MSTest.exe' returned an unexpected exit code. Expected '0'; actual '1'. 
      The previous error was converted to a warning because the task was called with ContinueOnError=true.
    C:Program FilesMSBuildMicrosoftVisualStudioTeamBuildMicrosoft.TeamFoundation.Build.targets(1406,5): warning MSB4018: The "TestToolsTask" task failed unexpectedly. [c:TFSCoreCrimeBuildTypeTFSBuild.proj]

If I run the mstest command directly on the build server via commandline without the switches it works fine. I don't understand why its trying to add these switches. any idea?

Answer 1

You need VS 2010 Premium or Ultimate installed to use those switches in MSTest.exe. You can get around this sort of by just doing an Exec of MSTest with the switches you want, but then you won't see the results as nicely in your build.
