title: How can I exclude a particular file from test coverage analysis?
body: <p>I have a few files in my Elixir application that I'd like to exclude from the test coverage reporting. I'm not using any fancy coverage tools right now; (though I'm not closed to the possibility of using such tools) I'm just using <code>mix test --cover</code> right now.</p>
  
  <p>How can I tell the coverage analysis tools that a given file should not be included in the coverage analysis?</p>
