title: How to get code coverage of files not hit by our test cases, it shows only which are hit
body: <p>We are working for getting code coverage by our test cases for the product. But the thing is that coverage tool does not show the files which are not at all hit. </p>
  
  <p>We are using coverage command to run our processes like this:</p>
  
  <p><em>coverage run -a --rcfile=/home/coveragerc -L </em></p>
  
  <p>So we get a code coverage of 57%. Which has all the files which are hit. If a file is not hit then it is not included in coverage calculation. So it files which are not hit, are calculated, then actual coverage will be around 45%.</p>
  
  <p>Please help how can I achieve it.</p>
