MSBuild/TFS Build property for the test results out directory path

I am running a build using TFS 2008 to build a Visual Studio 2010 solution. The build is set to run unit tests, and when it does, it creates a folder such as this to hold the test results:

D:\Temp\MyApp\MyApp.Dev\TestResults\MyAccount_MyBuildServerName 2010-07-29 18_07_00_Any CPU_Release\Out\

Is there a built-in property I can use in the TFSBuild.proj fi开发者_StackOverflowle to get the path above? I would like to reference something like "$(TestResultsOutFolderPath)" in my build file, but I don't know if such a property exists. So far the only properties I have found only get me to the "TestResults" level and do not add the dynamic folder that contains the timestamp info which I need. Thank you.

I guess there is no built-in property for that. But, you can create your own property in TFSBuild.proj under the PropertyGroup element like

<PropertyGroup>
<TestResultsOutFolderPath>...</TestResultsOutFolderPath>
</PropertyGroup>

you can create the full path by combining the built-in TFS properties some are listed at TFS Properties
