title: Can I merge Emma coverage data from unit and integration test targets?
body: <p>We have our TeamCity builds set up using a build chain, so that our unit tests and and integration tests can run in parallel when triggered by a commit:</p>
  
  <ul>
  <li>Build Chain - dependant on:
  
  <ul>
  <li>Unit tests</li>
  <li>Integration tests</li>
  </ul></li>
  </ul>
  
  <p>I am looking for a way that we can combine/merge the coverage data generated by the unit and integration tests in the build chain, so that we can get a better picture of how much <em>actual</em> code is covered by the two combined.</p>
  
  <p>The plan then is to be able to monitor changes in coverage of committed code, and perhaps failing builds if percentages fall!</p>
