phpunit ajax call test case using zend

How we can test a ajax call using phpunit zend.

This is my ajax call in controller

public function indexAction()
{   
    if ( $this->getRequest()->isPost() )
    {      

        if (self::isAjax()) {

            $name = $this->getRequest()->getParam('name');
            $email = $this->getRequest()->getParam('email');开发者_Go百科            


             $u = new admin_Model_User();
             $u->email = $email;
             $u->name = $name;             
             $u->save();

            if(!empty($u->id)) $msg = "Record Successfully Added";
            else $msg = "Records could not be added";


            $this->results[] = array('status'=>true, 'msg'=>$msg);


            echo $this->_helper->json($this->results);
        } else {
        echo "none-Ajax Request";
    }
    }else {

    echo "Request not post";
}
}

private function isAjax() {
    return (isset($_SERVER['HTTP_X_REQUESTED_WITH']) && strtolower($_SERVER['HTTP_X_REQUESTED_WITH']) == 'xmlhttprequest');
}

here is my test case

    class AjaxjsonControllerTest extends ControllerTestCase
    {
    // testing not post area
    public function testIndexAction() {
        $this->dispatch('/ajaxjson');
        $this->assertModule('admin');
        $this->assertController('Ajaxjson');
        $this->assertAction('index');
    }
// testing not ajax request
public function testIndexNonajaxAction() {
        $request = $this->getRequest();  
      $request->setMethod('POST');
      $request->setPost(array(
        'name' => 'name bar',
        'email' => 'email x',
      ));

        $this->dispatch('/ajaxjson');
        $this->assertModule('admin');
        $this->assertController('Ajaxjson');
        $this->assertAction('index');
    }

        public function testPostAction() {
              $request = $this->getRequest();
              //$request->setHeader('X_REQUESTED_WITH','XMLHttpRequest');
              $request->setHeader('HTTP_X_REQUESTED_WITH','XMLHttpRequest');

              $request->setMethod('POST');
              $request->setPost(array(
                'name' => 'name bar',
                'email' => 'email x',
              ));

              $this->dispatch('/ajaxjson');
            }

    }

but this is not working. Has anyone an idea?

First, PHPUnit typically runs via the console. When I check the $_SERVER variable via tests that I run, it is a lot different than what would be found in a web server. In your isAjax method, you should use something like:

$this->getRequest()->getHeaders() // array of headers
$this->getRequest()->getHeader('HTTP_X_REQUESTED_WITH'); //specific header

If you really, really want to use $_SERVER in your controller, then why not just set the $_SERVER variable in the test?

$_SERVER['HTTP_X_REQUESTED_WITH'] = 'XMLHttpRequest';
      $request->setMethod('POST');
          $request->setPost(array(
            'name' => 'name bar',
            'email' => 'email x',
          ));
$this->dispatch('/ajaxjson');

Secondly and more importantly, you are not actually testing anything... You should have an assert in the test method. At it's most basic, you can use

   $this->assertController('ajaxjson');
   $this->assertAction('index');

But you really should be setting up multiple tests for this action. A test for

1. when the request is not a post
2. When request is not ajax
3. when user is saved
4. when user is not saved
