Problem running a custom test type with MSTest

Question

I've created a custom test type using the Visual Studio SDK.  The test type executes correctly when the tests are run as part of a test project inside visual studio.  However, when I attempt to run the same test project using MSTest and the /testcontainer: option, MSTest prints a message saying that no tests were found.  To register the test type I copied the .dll to private assemblies, registered the package using regpkg.exe, and then used regedit to make the following alterations to the system registry:

[HKEY_LOCAL_MACHINE\%RootHive%\EnterpriseTools\QualityTools\HostAdapters\Regression Test\SupportedTestTypes]
    "{3451566B-E89A-4b09-AC24-6CB67CFB8A04}"="Regression Test"
    "{13cdc9d9-ddb5-4fa4-a97d-d965ccfc6d4b}"="Unit Test"
    [HKEY_LOCAL_MACHINE\%RootHive%\EnterpriseTools\QualityTools\TestTypes\{13cdc9d9-ddb5-4fa4-a97d-d965ccfc6d4b}\SupportedHostAdapters]
   "Regression Test"="Regression Test Host Adapter"
   [HKEY_LOCAL_MACHINE\%RootHive%\EnterpriseTools\QualityTools\TestTypes\{3451566B-E89A-4b09-AC24-6CB67CFB8A04}\SupportedHostAdapters]
    "Regression Test"="Regression Test Host Adapter"[HKEY_LOCAL_MACHINE\%RootHive%\EnterpriseTools\QualityTools\HostAdapters\Regression Test\SupportedTestTypes]
   "{3451566B-E89A-4b09-AC24-6CB67CFB8A04}"="Regression Test"
    "{13cdc9d9-ddb5-4fa4-a97d-d965ccfc6d4b}"="Unit Test"
   [HKEY_LOCAL_MACHINE\%RootHive%\EnterpriseTools\QualityTools\TestTypes\{13cdc9d9-ddb5-4fa4-a97d-d965ccfc6d4b}\SupportedHostAdapters]
    "Regression Test"="Regression Test Host Adapter"
    [HKEY_LOCAL_MACHINE\%RootHive%\EnterpriseTools\QualityTools\TestTypes\{3451566B-E89A-4b09-AC24-6CB67CFB8A04}\SupportedHostAdapters]
    "Regression Test"="Regression Test Host Adapter"

Windows Registry Editor Version 5.00
    [HKEY_LOCAL_MACHINE\%RootHive%\EnterpriseTools\QualityTools\Xml\http://microsoft.com/schemas/VisualStudio/SDK/Samples/RegressionTest/2010/06]
    "XsdLocation"="%VSXsdLocation:\=\\%"
   [HKEY_LOCAL_MACHINE\%RootHive%\EnterpriseTools\QualityTools\Xml\http://microsoft.com/schemas/VisualStudio/SDK/Samples/RegressionTest/2010/06\ElementToClass]
    "RegressionTestRunConfig"="Microsoft.VisualStudio.TestTools.Samples.RegressionTestRunConfig, Microsoft.VisualStudio.QualityTools.Samples.RegressionTestTIP"
    "RegressionTestHostRunConfig"="Microsoft.VisualStudio.TestTools.Samples.RegressionHostRunConfigData, Microsoft.VisualStudio.QualityTools.Samples.RegressionTestTIP"
    "RegressionTestResult"="Microsoft.VisualStudio.TestTools.Samples.RegressionTestResult, Microsoft.VisualStudio.QualityTools.Samples.RegressionTestTIP"
     "RegressionTest"="Microsoft.VisualStudio.TestTools.Samples.RegressionTest, Microsoft.VisualStudio.QualityTools.Samples.RegressionTestTIP"

I'm not sure if these MSTest problems are coming from an error in my test type or my registration process.  Any help would be appreciated.

Hi rmcglaughlin,

Thank you for posting in the MSDN forum.

I am trying to involve someone familiar with this topic to further look at this issue. There might be some time delay. Appreciate your patience.

Would you please tell the Visual Studio version you're running? I ask because the process could be different between VS versions.

• Process of extending test type in VS 2010 like: http://archive.msdn.microsoft.com/CustomTestTypeSample There's a batch script to deploy the test type.
• Process of authoring new VS Unit test adapter (VS 11 beta) like: http://blogs.msdn.com/b/bhuvaneshwari/archive/2012/03/13/authoring-a-new-visual-studio-test-adapter.aspx

best regards,

I managed to run the test using the /testmetadata option and a metadata file which will work for my purposes.
