title: Generating a code coverage report with PHPUnit
body: <p>Does anyone know the correct command line to generate a code coverage file on a PHP project? I've already installed the XDebug tool.</p>
  
  <p>In the official documentation from PHPUnit, I found the following command line, but it is not working:</p>
  
  <pre><code>phpunit --coverage-text=&lt;file&gt; 
  </code></pre>
  
  <p>where  is the file where output is going to be stored.</p>
  
  <p>I don't have any tests yet, but is there a way to generate a report file, even though there are no tests in the project?</p>
