title: analysis of code coverage
body: <p>I am working with asp.net web forms project developed in framework 4.0. It does not have any unit tests at present. </p>
  
  <p>I am currently adding a new feature to the site in which I hope to introduce unit and integration tests for. Not being familiar with the concept of code coverage I hope to achieve a high percentage of such for the new feature.</p>
  
  <p>I will be using the integrated test environment supplied with visual studio and rhino mocks for mock generation. For a new feature, what level of code coverage should I look to achieving? And for a novice to code coverage, how can this be measured for a specific feature of the site?</p>
