title: PHPUnit test classes with camel case or underscore
body: <p>When writing test cases inthe xUnit style that PHPUnit follows it seems that everyone follows the camel case convention for function names:</p>
  
  <pre><code>public function testObjectHasFluentInterface()
  {
      // ...
  }
  </code></pre>
  
  <p>I have been naming my methods with a more "eloquent" PHPSpec style:</p>
  
  <pre><code>public function test_it_has_a_fluent_interface()
  {
      // ...
  }
  </code></pre>
  
  <p>Will this style create problems for me in the future? Personally I find it vastly more readable and easy to come back to.</p>
