title: How to set test category for all tests in the class
body: <p>I am using <a href="https://en.wikipedia.org/wiki/MSTest" rel="noreferrer">MSTest</a>, and I want to set the same test category for all methods in test class at once, without setting TestCategory attribute to each method individually. How can this be done?</p>
  
  <p>The most convenient and obvious way would be to set TestCategory attribute on class, but it can be applied to methods only.</p>
  
  <p>The ultimate goal is to skip integration tests during test run on TFS check-in.</p>
