Once you have your bootstrap in place, you can begin testing. Testing is basically as you would expect in an PHPUnit test suite, with a few minor differences.
First, you will need to dispatch a URL to test, using the
dispatch() method of the TestCase:
<?php
class IndexControllerTest extends Zend_Test_PHPUnit_ControllerTestCase
{
// ...
public function testHomePage()
{
$this->dispatch('/');
// ...
}
}
There will be times, however, that you need to provide extra
information -- GET and POST variables, COOKIE information, etc. You can
populate the request with that information:
<?php
class FooControllerTest extends Zend_Test_PHPUnit_ControllerTestCase
{
// ...
public function testBarActionShouldReceiveAllParameters()
{
// Set GET variables:
$this->request->setQuery(array(
'foo' => 'bar',
'bar' => 'baz',
));
// Set POST variables:
$this->request->setPost(array(
'baz' => 'bat',
'lame' => 'bogus',
));
// Set a cookie value:
$this->request->setCookie('user', 'matthew');
// or many:
$this->request->setCookies(array(
'timestamp' => time(),
'host' => 'foobar',
));
// Set headers, even:
$this->request->setHeader('X-Requested-With', 'XmlHttpRequest');
// Set the request method:
$this->request->setMethod('POST');
// Dispatch:
$this->dispatch('/foo/bar');
// ...
}
}
Now that the request is made, it's time to start making assertions against it.
Important
The redirect action helper issues an exit() statement
when using the method gotoAndExit()
and will then obviously also stops a test running for this method.
For testability of your application dont use that method on the
redirector!
Due to its nature the redirector action helper plugin issues a redirect
and exists after this. Because you cannot test parts of an application
that issue exit calls Zend_Test_PHPUnit_ControllerTestCase
automatically disables the exit part of the redirector which can cause
different behaviours in tests and the real application. To make sure
redirect work correctly you should it them in the following way:
<?php
class MyController extends Zend_Controller_Action
{
public function indexAction()
{
if($someCondition == true) {
return $this->_redirect(...);
} else if($anotherCondition == true) {
$this->_redirector->gotoSimple("foo");
return;
}
// do some stuff here
}
}
Important
Depending on your application this is not enough as additional action,
preDispatch() or postDispatch()
logic might be executed. This cannot be handled in a good way with Zend Test
currently.
