MSTest on build-server

Keept getting errormessages like the following

C:\Program Files (x86)\MSBuild\14.0\bin\Microsoft.Common.CurrentVersion.targets(1819,5): 
warning MSB3245: 
Could not resolve this reference. 
Could not locate the assembly "Microsoft.VisualStudio.QualityTools.UnitTestFramework, Version=, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a, processorArchitecture=MSIL". 
Check to make sure the assembly exists on disk. If this reference is required by your code, you may get compilation errors.

Turns out there is a simpler solution than installing Visual Studio on the build-server.
there is a nuget package that resolves this error

PM> Install-Package Microsoft.VisualStudio.QualityTools.UnitTestFramework.Updated
