ZF2 Testing: Failed asserting response code “302”,

Question

I am implementing PHPUnit tests for an AuthenticationController. When I test the /logout route:

public function testLogoutActionCanBeAccessed()
{
    $this->dispatch('/logout');
    $this->assertResponseStatusCode(302);

    $this->assertModuleName('Main');
    $this->assertControllerName('Main\Controller\Authentication');
    $this->assertControllerClass('AuthenticationController');
    $this->assertMatchedRouteName('logout');
}

I get the following error message:

There was 1 failure:

1) MainTest\Controller\AuthenticationControllerTest::testLogoutActionCanBeAccessed
Failed asserting response code "302", actual status code is "500"

The logout code is the following:

public function logoutAction()
{
    $this->loginLogoutService->logout();

    return $this->redirect()->toRoute('home');
}

and

public function logout() {
    $this->authservice->getStorage()->forgetMe();
    $this->authservice->clearIdentity();
}

and

$this->authservice = new AuthenticationService();

When I debug my app step-by-step, the $actionResponse status code is 302 and the application works fine. 500 is internal server error. I have no idea where it is coming from.

Anyone has some idea?

P.S.:

public function setUp()
{

    $this->setApplicationConfig(
        include '/../../../../../config/application.config.php'
    );
    parent::setUp();
}

I had same problem too. In my case in one of previous tests session was already started and consequently headers was sent. As a result I've got such side effect. One of solutions is run such tests separately from each other. Or maybe better use another testing tool like selenium for test like this.
