- library - модульные- application - интеграционные+ functional - функциональные+ perfomance — функциональные

Тестировать не нужно

- Zend Framework- Doctrine / Propel- Jquery / Prototype / Dojo- Symphony DI / Crafty / DI- all extenal libraries ...

Тестировать нужно

- Абстрактные классы и интефейсы- Базовые компонеты- Магическую инициализацию- Любые не очевидные вещи

DRY – не повторяться1 тест – 1 проверкаХороший тест – 5 строкЕсли что-то протестировано, не тетсируем это снова

/test/tests/application/controllers# cat IndexControllerTest.php

namespace Test;class IndexController extends \Zend\Test\PHPUnit\ControllerTestCase{ public $bootstrap = '../../bootstrap.php'; /** * @group Bug123 * @cover IndexController::indexAction */ public function testIndexAction() { $this->dispatch('/'); $this->assertController("index"); $this->assertAction("index"); }}

Тестирование Controller

Тестирование Controller

class IndexController extends \Zend\Test\PHPUnit\ControllerTestCase public function testIndexAction() $this->dispatch('/'); $this->assertController("index"); $this->assertAction("index"); $this->assertQueryContentContains('#content', 'Hello Im here'); $this->assertQueryContentContains('div.content', 'Hello Im here'); $this->assertQueryContentContains('body .content', 'Hello Im here'); $this->assertQueryCount('#categories li', 3);

<?phpclass IndexController extends AbstractController

public function indexAction() $this->view->hello = 'Im here';

Тестирование Controller::init

<?php

abstract class AbstractController extends \Zend\Controller\Action{ public function init() { $this->_helper->contextSwitch() ->addActionContext('index', array('xml', 'json')) ->setAutoJsonSerialization(true) ->initContext();

$this->view->categories = new Application\Model\CategoryMapper(); }}

Тестирование Controller:init

class AbstractController extends \Zend\Test\PHPUnit\ControllerTestCase

public function testInitContext() $controller = new AbstractControllerStub($this->getRequest(), $this->getResponse()); $this->assertEquals( $controller->getHelper('ContextSwitch')->getActionContexts('index'), array('xml', 'json'));

public function testInitCategories() $controller = new AbstractControllerStub($this->getRequest(), $this->getResponse()); $this->assertType('Application\\Model\\CategoryMapper', $controller->view->categories);

Тестирование Form

<?phpnamespace Application\Form;class Registration extends \Zend\Form\Form public function init() $this->addElement('text', 'username'); $this->addElement('text', 'password'); $this->addElement('text', 'password_retype');

public function isValid($params) $result = parent::isValid($params); if ($this->getValue('password')!=$this->getValue('password_retype')) { return false; } return $result;

Тестирование Form

class Registration extends \PHPUnit_Framework_TestCase public function testValidate() $form = new \Application\Form\Registration; $this->assertTrue($form->isValid(array( 'username' => 'test', 'password' => '123', 'password_retype' => '123', ))); public function testValidateFail() $form = new \Application\Form\Registration; $this->assertFalse($form->isValid(array( 'username' => 'test', 'password' => '123', 'password_retype' => '1234', )));

Архитектура

→ getConnection→ getDataSet→ createDbTableDataSet→ createDbTable→ createDbRowset

Тестирование DbTable

$categories = new \Application\Model\DbTable\Categories($this->getAdapter()); $categories->insert(array('id'=>4, 'name'=>'test')); $this->assertDataSetsEqual( $this->createFlatXmlDataSet("_fixtures/categoriesInsert.xml"), $this->createDbTableDataSet(array($categories)) );

Тестирование DbTable

class CategoriesTest extends \Zend\Test\PHPUnit\DatabaseTestCase

public function getConnection() $application = new Application (_ENV, _PATH . '/configs/application.ini'); $application->bootstrap(); $resource = $application->getBootstrap()->getPluginResource('db'); return $this->createZendDbConnection($resource->getDbAdapter(), 'any');

public function getDataSet() return $this->createFlatXMLDataSet(__DIR__ . '/_fixtures/categories.xml');

public function testFecthAll() $categories = new \Application\Model\DbTable\Categories($this->getAdapter()); $rowset = $categories->fetchAllOrdered(); $this->assertEquals(count($rowset), 3);

Тестирование DbTable

<?xml version="1.0" encoding="UTF-8"?><dataset> <categories id="1" name="cat1" /> <categories id="3" name="cat3" /> <categories id="2" name="cat2" /></dataset>

<?xml version="1.0" encoding="UTF-8"?><dataset> <categories id="1" name="cat1" /> <categories id="3" name="cat3" /> <categories id="2" name="cat2" /> <categories id="4" name="test" /></dataset>

Тестирование Mapper

1. Использует сервис/сервисы2. Используется моделями3. Содержит код setTable/getTable/__construct/init которые идентичны и миргурируют из одного маппера в другой

+ есть еще внешние источники данных SOAP/XML-RPC/REST/RSS

Тестирование Mapper

<?phpnamespace Application\Model;

class XXXMapper{ protected $_table = null;

protected $_defaultServiceName = '';

public function __construct(DbTable $table=null)

public function getTable()

public function setTable(DbTable $table) …}

Тестирование Mapper

Выделить общий класс AbstractMapper Выделить интерфейс для сервисов Наследовать все мапперы от абстрактного Имплементировать интерфейс Service в DbTable

Тестирование Mapper

<?phpnamespace Application\Model;class AbstractMapper{ protected $_service = null; protected $_defaultServiceName = ''; public function __construct(Service $service=null) { if (is_null($service)) { $name = $this->_defaultServiceName; $this->setService(new $name); } else { $this->setService($this->_service = $service); } }

public function getService()

public function setService(Service $service)}

Тестирование Mapper

Создаем реализации Складываем в подпапку _files в текущей директории

__Construct / Abstract class / Interface

<?phpnamespace Test;

class AbstractMapperMockAutoload extends \Application\Model\AbstractMapper{ protected $_defaultServiceName = 'Test\ServiceMock';}

Тестирование Mapper

class AbstractMapperTest extends \PHPUnit_Framework_TestCase

public function testInit() $mock = new AbstractMapperMockAutoload(); $this->assertType('Test\\ServiceMock', $mock->getService());

public function testInitFail() try { $mock = new AbstractMapperMock(); } catch (\Exception $e) { return ; } $this->fail('An expected exception has not been raised.'); public function testSet() $mock = new AbstractMapperMockAutoload(); $mock->setService(new ServiceMock()); $this->assertType('Test\\ServiceMock', $mock->getService());
