title: In CakePHP, how can I see which fixtures were actually used?
body: <p>I have a test class with lots of tests. I just moved several of them to a separate test file. How can I find out which fixtures are safe to remove from the test.</p>
  
  <p>Obviously, I can comment out each fixture one-by-one and see if it breaks. But I'm wondering if there is a type of log I can look at that will show which fixtures were actually used.</p>
  
  <p>(If it matters I'm using the latest version of CakePHP 2, but we'll be moving to 3 soon.)</p>
