title: PHP Unit Testing Coverage
body: <p>I'm new to PHP development but have experience developing Python web applications.  In Python, there is a package called <a href="https://pypi.python.org/pypi/coverage" rel="noreferrer">Coverage</a> that analyzes the code and identifies functionality that is missing Unit Tests.</p>
  
  <p>Does such a package exist in the PHP world?  I have searched Google and SO and come up short.  Thank you for your help!</p>
