title: Visual Studio 2012 menu 'analyze code coverage' is missing
body: <p>There is this great tool in Visual Studio 2012 to show the test coverage of the source code. On the <a href="http://msdn.microsoft.com/en-us/library/dd537628.aspx">official MSDN homepage</a> it is shown under menu <code>Test -&gt; Analyze Code Coverage</code>.</p>
  
  <p>But in my <code>Test</code> menu this entry is missing and I could'nt figure out why. Can someone please explain? Am I missing an addon/plugin?</p>
  
  <p><strong>Update:</strong> Visual Studio 2012 Professional with Update 3.</p>
