Description

This recipe is useful when you have a large suite of unit tests and you don't want to be burdened with maintaining Test List (*.vsmdi) files.

This works out of the box on a TFS 2008 Team Build.

However, there is a problem if you want to run the script as a Desktop Build (http://msdn2.microsoft.com/en-us/library/ms181292.aspx). The bug in Team Build 2008 https://connect.microsoft.com/VisualStudio/feedback/ViewFeedback.aspx?FeedbackID=324863.

Usage

Add to TFSBuild.proj

Script

    <!-- TFS Build 2008.
         This snippet finds assemblies matching the pattern *.Tests.dll in the
         output directory of the build.

         It then creates the TestContainer and LocalTestContainer items so that
         the <TestToolsTask> is able to run MSTest.exe.
    -->


<Target Name="BeforeTestConfiguration">

    <Message Text="Using unit tests from: $(BinariesRoot)\$(Configuration)\*.Tests.dll"
             Condition=" '$(IsDesktopBuild)'=='true' " />

    <CreateItem Include="$(BinariesRoot)\$(Configuration)\*.Tests.dll">
     <Output TaskParameter="Include" ItemName="LocalTestContainer"/>
     <Output TaskParameter="Include" ItemName="TestContainer"/>
    </CreateItem>

    <Message Text="LocalTestContainer: @(LocalTestContainer)"
             Condition=" '$(IsDesktopBuild)'=='true' " />

</Target>

Notes

• Currently it matches all *.Tests.dll outputs in the \Binaries\Release\ folder. If your test assemblies are named differently, you will need to update this.
• It might be useful to store this workaround in a TestContainerWorkaround.targets file, then add an <Import Project="TestContainerWorkaround.targets" />.
