title: CakePHP integration tests - Is there something else to test?
body: <p>I have methods like this in my code.</p>
  
  <pre><code>    public function businessDepartments()
  {
      $this-&gt;paginate = [
          'conditions' =&gt; [
              'Tags.tag_type_id' =&gt; 'businessDepartment'
          ]
      ];
      parent::_index();
  
      $this-&gt;set('columns', [
          'tag_value' =&gt; ['title' =&gt; __d('cockpit', 'Business department')],
          'sort' =&gt; ['title' =&gt; __d('cockpit', 'Sorting')]
      ]);
      $this-&gt;_setURLsWhenAdd();
  }
  </code></pre>
  
  <p>I can call this method with the class "Tags" and action "businessDepartment". 
  This is how _setURLWhenAdd() looks like. </p>
  
  <pre><code>    /**
   * this method is setting the URLs inside the add
   * @return setter
   */
  protected function _setURLsWhenAdd()
  {
      // Set a new Url for the Add-Button in the index-View
      $this-&gt;set('dataAjaxUrl', "/tags/add/businessDepartment");
  
      // Sets the refreshable-Class on the element and the ajax-url where the element can get fresh data
      $this-&gt;set('refreshable', '/tags/businessDepartments');
  }
  </code></pre>
  
  <p>I have a test which look like this. </p>
  
  <pre><code>public function testBusinessDepartments()
  {
      $this-&gt;get('/tags/businessDepartments');
      $this-&gt;assertResponseOk();
  }
  </code></pre>
  
  <p>Is this what I want to test ? Could/should I test something more ? Except entrance and response from this method ?</p>
