MsTest is not available from Visual Studio

I have Visual Studio 2010 Ultimate but it looks like mstest is not available: there are no mstest templates at "Add new item" and I see no reference to Microsoft.VisualStudio.QualityTools at "Add reference" dialog. What should I do to ena开发者_如何学Pythonble mstest?

It is a project template, not an item template. File + Add + Project, pick from the Test Projects node.
