Zend_Test_PHPUnit_ControllerTestCase and Zend_Layout, unable to find Layout plugin while running tests

Question

I am starting to write some test cases for controller classes using Zend Framework 1.10.6 and Zend_Test_PHPUnit_ControllerTestCase. I am having problems with one item, which is that while the test cases are running, Zend_Controller_Action_HelperBroker can't find the Layout action helper.

Here are the bare bones of my test case:

require_once 'PHPUnit/Framework.php';
require_once 'Zend/Test/PHPUnit/ControllerTestCase.php';
require_once 'controllers/IndexController.php';

class Application_Controllers_IndexControllerTest extends Zend_Test_PHPUnit_ControllerTestCase {

    public $_application;

    protected function setUp() {
        $this->bootstrap = array($this, 'appBootstrap');
        parent::setUp ();
    }

    public function appBootstrap() {
        // Create application, bootstrap, but don't run
        $this->_application = new Zend_Application(
            APPLICATION_ENV,
            APPLICATION_PATH . '/configs/application.ini'
        );
        $this->_application->bootstrap();
        $this->getFrontController()->setParams($this->_application->getOptions())
             ->addControllerDirectory(APPLICATION_PATH . '/controllers');
    }

    public function testIndexAction() {
        $this->dispatch('/index/index');
        $this->assertController('index');
        $this->assertAction('index');
    }

}

I get an exception when I run the test case:

Zend_Controller_Action_Exception: Action Helper by name Layout not found

When I comment out the two lines in class Zend_Controller_Action_HelperBroker to try to find the source of this around line 368, I get:

Zend_Loader_PluginLoader_Exception: Plugin by name 'Layout' was not found in the registry; used paths: Zend_Controller_Action_Helper_: Zend/Controller/Action/Helper/

The loading of layout scripts works fine in my application when running, it appears that the correct path or registry for the Zend_Controller_Action_Helper can't be found while running tests under PHPUnit and therefore the Layout plugin can't be loaded.

I have verified that Zend is installed correctly and that Layout.php is in the correct place.

Any ideas?

At which point do you add your Layout code?

Remember that the 'boostraping' is different when running a PHPUnit test, and that things that are bootstrapped in your main app might not be when running as a PHPUnit test.
