We are testing a simple controller from imaginable MVC framework.

<?php
class UserController extends AbtractController {

    public function show($id)
    {
        $user = $this->db->find('users',$id);
        if (!$user) return $this->render404('User not found');
        $this->render('show.html.php', array('user' => $user));
        return true;
    }
}

How It Is Tested With Codeception PHP framework:

It's a new testing framework. It's here, on GitHub: https://github.com/Codeception/Codeception

<?php
class UserControllerCest {
    public $class = 'UserController';

    public function show(CodeGuy $I) {
        // prepare environment
        $I->haveFakeClass($controller = Stub::make($this->class, array('render' => function() {}, 'render404' => function() {})))
            ->haveFakeClass($db = Stub::make('DbConnector', array('find' => function($id) { return $id > 0 ? new User() : null )))
            ->setProperty($controller, 'db', $db);

        $I->executeTestedMethodOn($controller, 1)
            ->seeResultEquals(true)
            ->seeMethodInvoked($controller, 'render');

        $I->expect('it will render404 for unexistent user')
            ->executeTestedMethodOn($controller, 0)
            ->seeResultNotEquals(true)
            ->seeMethodInvoked($controller, 'render404','User not found')
            ->seeMethodNotInvoked($controller, 'render');
    }
}

How It Is Tested With PHPUnit

<?php

class UserControllerTest extends PHPUnit_Framework_TestCase
{
    protected function prepareController()
    {
        $controller = $this->getMock('UserController', array('render', 'render404'), null, false, false);
        $db = $this->getMock('DbConnector');
        $db->expects($this->any())
            ->method('find')
            ->will($this->returnCallback(function ($id)
        {
            return $id > 0 ? new User() : null;
        }));

        // connecting stubs together
        $r = new ReflectionObject($controller);
        $dbProperty = $r->getProperty('db');
        $dbProperty->setAccessible(true);
        $dbProperty->setValue($controller, $db);

    }

    public function testShowForExistingUser()
    {
        $controller = $this->prepareController();
        $controller->expects($this->once())->method('render')->with($this->anything());
        $this->assertTrue($controller->show(1));
    }

    public function testShowForUnexistingUser()
    {
        $controller = $this->prepareController();
        $controller->expects($this->never())->method('render')->with($this->anything());
        $controller->expects($this->once())
            ->method('404')
            ->with($this->equalTo('User not found'));

        $this->assertNotEquals(true, $controller->show(0));
    }
}
