title: how to get which statements are missed in python test coverage
body: <p>I am new to python, 
  I have written test cases for my class ,
  I am using 
  <code>python -m pytest --cov=azuread_api</code> to get code coverage.</p>
  
  <p>I am getting coverage on the console as <a href="https://i.stack.imgur.com/iKRNP.png" rel="noreferrer"><img src="https://i.stack.imgur.com/iKRNP.png" alt="enter image description here"></a></p>
  
  <p>How do I get which lines are missed by test for e.g in aadadapter.py file</p>
  
  <p>Thanks,</p>
