title: Incomplete tests when using Mockery
body: <p>Let's say I'm testing that a method calls another method in php</p>
  
  <pre><code>&lt;?php
  use \Mockery as m;
  
  public function testMethodCallsOtherMethod {
      $m = m::Mock(new StdClass);
      $m-&gt;assertCalledWith('methodName')-&gt;once();
      doSomethingSoMCallsMethodName($m);
  }
  
  function tearDown() {
      m::close();
  }
  </code></pre>
  
  <p>When I run this test with PHPUnit it reports the test is incomplete, because there's no PHPUnit assertion in the test. However it is a valid test and will error if the method is not called. Any good solutions for getting PHPUnit to realize this is a valid test?</p>
