[fw-mvc] unit test and set layout

Hi,

Zend Framework 1.9.2

I am writing a unit test for controller IndexController.php, which use
a different Layout:

---
application/controllers/IndexController.php
---
function indexAction()
{
$this->_helper->layout->setLayout('dashboard');
$this->_helper->actionStack('problem-dashboard', 'job');
$this->_helper->actionStack('problem-dashboard', 'volume');
$this->_helper->actionStack('next-dashboard', 'job');
$this->_helper->actionStack('running-dashboard', 'job');
$this->_helper->actionStack('terminated-dashboard', 'job');
}
---

That part "bootstrap.php" for unit tests:

---
tests/application/bootstrap.php
---
...
Zend_Layout::startMvc(array(
'layoutPath' => $appRoot . '/application/layouts/' . $config_layout->path,
'layout' => 'main'
));
...
---

Here's my test:

---
tests/application/controllers/IndexControllerTest.php
---
public function testIndex() {
$this->dispatch('index/index');
echo $this->response->outputBody(); // for debug !!!
$this->assertResponseCode(200);
$this->assertModule('default');
$this->assertController('index');
$this->assertAction('index');
// other asserts ...
}
---

This test fails. If I turn on the output "echo
$this->response->outputBody();", I see this:

If I modify a test, like this:

---NEW---
tests/application/controllers/IndexControllerTest.php
---
public function testIndex() {
$this->dispatch('index/index/test/1'); // workaround
...
}
---

And new IndexController.php :

---NEW---
application/controllers/IndexController.php
---
function indexAction()
{
// workaround
$unit_test = $this->_request->getParam('test', null);
if ( empty($unit_test)) {
// not test
$this->_helper->layout->setLayout('dashboard');
}
...
$this->_helper->actionStack('problem-dashboard', 'job');
$this->_helper->actionStack('problem-dashboard', 'volume');
$this->_helper->actionStack('next-dashboard', 'job');
$this->_helper->actionStack('running-dashboard', 'job');
$this->_helper->actionStack('terminated-dashboard', 'job');
}
---

That test works OK.

Question: why does not work if I use
"$this->_helper->layout->setLayout('dashboard')" ?
