在Phpunit类中加载Zend-Framework模型

I want to call my zend-framework model and use there functions in AuthenticationControllerTest.php but I am getting error when i run it from terminal.

 - -MyZendproject
 - -application
    -model
     -testmodel
 - +public
 - -tests
   - aplication
     - controller
       - .AuthenticationControllerTest.php

Here is my AuthenticationControllerTest.php file

<?php
require_once `PHPUnit/Framework/TestCase.php`;

defined(`APPLICATION_PATH`)
        || define(`APPLICATION_PATH`, realpath(dirname(__FILE__) . `/../application`));

    // Define application environment
        defined(`APPLICATION_ENV`) || define(`APPLICATION_ENV`, `tests`);

        // Ensure library/ is on include_path
        set_include_path(implode(PATH_SEPARATOR,
                array(realpath(APPLICATION_PATH . `../../../library`), get_include_path())));

        // Zend_Application
        require_once `Zend/Application.php`;

        $application = new Zend_Application(
                APPLICATION_ENV,
                realpath(APPLICATION_PATH .`configs/application.ini`)
        );
class AuthenticationControllerTest extends PHPUnit_Framework_TestCase
{
     public function testLoginRetriespLogin() {
      $testmodel = new Model_testmodel_Object();//my model
    }   
}

but when run it from terminal "phpunit AuthenticationControllerTest" it give me error:

$ phpunit AuthenticationControllerTest

..FPHP Fatal error: Class 'Model_testmodel_Object' not found in /var/www/versioned/pm160form/tests/application/controllers/AuthenticationControllerTest.php on line 146

Looks like your test suit folder is not resolving towards the actual application folder. See how you have

|| define(`APPLICATION_PATH`, realpath(dirname(__FILE__) . `/../application`));

but your dirname is currently pointing to the test/application/controller directory which, of course, does not have your actual application. Try pointing the application folder that is under the top root instead,

|| define(`APPLICATION_PATH`, realpath(dirname(__FILE__) . `/../../../application`));

Also, take care to follow the standard of using PHP Unit in Zend Framework as described at http://framework.zend.com/manual/1.12/en/zend.test.phpunit.html . The framework needs to be fully bootstraped before the autoloader can work.
