Unit testing zend framework apps Unit testing zend framework apps Presentation Transcript

  • Unit TestingZend Framework Apps ZendCon 2011, Santa Clara CA, USA
  • Michelangelo van Dam• Independent Consultant• Zend Certified Engineer (ZCE)• President of PHPBenelux
  • The saga continues…
  • Zend Webinarhttp://www.zend.com/en/resources/webinars/framework
  • Any reasons not to test?
  • Most common excuses• no time• not within budget• development team does not know how• tests are provided after delivery•…
  • NO EXCUSES!
  • The cost of bugs Bugs Costs Unittests100 75 50 25 0 Start Milestone1 Milestone2 Milestone3
  • Maintainability•- during development test will fail indicating bugs•- after sales support testing if an issue is genuine - fixing issues won’t break code base ‣ if they do, you need to fix it!• long term projects - refactoring made easy
  • Confidence•- for the developer code works•- for the manager project succeeds•- for sales / general management / share holders making profit•- for the customer paying for what they want
  • Unit testing ZF apps
  • Setting things up
  • phpunit.xml<phpunit bootstrap="./TestHelper.php" colors="true"> <testsuite name="Unit test suite"> <directory>./</directory> </testsuite> <filter> <whitelist> <directory suffix=".php">../application/</directory> <directory suffix=".php">../library/Mylib/</directory> <exclude> <directory suffix=".phtml">../application/</directory> </exclude> </whitelist> </filter></phpunit>
  • TestHelper.php<?php// set our app paths and environmentsdefine(BASE_PATH, realpath(dirname(__FILE__) . /../));define(APPLICATION_PATH, BASE_PATH . /application);define(TEST_PATH, BASE_PATH . /tests);define(APPLICATION_ENV, testing);// Include pathset_include_path( . PATH_SEPARATOR . BASE_PATH . /library . PATH_SEPARATOR . get_include_path());// Set the default timezone !!!date_default_timezone_set(Europe/Brussels);// We wanna catch all errors en strict warningserror_reporting(E_ALL|E_STRICT);require_once Zend/Application.php;$application = new Zend_Application( APPLICATION_ENV, APPLICATION_PATH . /configs/application.ini);$application->bootstrap();
  • Zend_Tool since 1.11.4• provides • phpunit.xml • bootstrap.php • IndexControllerTest.php Ralph Schindler
  • Start your engines! http://www.flickr.com/photos/robdunckley/3781995277
  • Testing Zend_Form
  • CommentForm Name:E-mail Address: Website: Comment: Post
  • Start with the test<?phpclass Application_Form_CommentFormTest extends PHPUnit_Framework_TestCase{ protected $_form; protected function setUp() { $this->_form = new Application_Form_CommentForm(); parent::setUp(); } protected function tearDown() { parent::tearDown(); $this->_form = null; }}
  • The good stuffpublic function goodData(){ return array ( array (John Doe, john.doe@example.com, http://example.com, test comment), array ("Matthew Weier OPhinney", matthew@zend.com, http://weierophinney.net, Doing an MWOP-Test), array (D. Keith Casey, Jr., Keith@CaseySoftware.com, http://caseysoftware.com, Doing a monkey dance), );}/** * @dataProvider goodData */public function testFormAcceptsValidData($name, $email, $web, $comment){ $data = array ( name => $name, mail => $mail, web => $web, comment => $comment, ); $this->assertTrue($this->_form->isValid($data));}
  • The bad stuffpublic function badData(){ return array ( array (,,,), array ("Robert; DROP TABLES comments; --", , http://xkcd.com/327/,Little Bobby Tables), array (str_repeat(x, 100000), , , ), array (John Doe, jd@example.com, "http://t.co/@"style="font-size:999999999999px;"onmouseover="$.getScript(http:u002fu002fis.gdu002ffl9A7)"/", exploit twitter 9/21/2010), );}/** * @dataProvider badData */public function testFormRejectsBadData($name, $email, $web, $comment){ $data = array ( name => $name, mail => $mail, web => $web, comment => $comment, ); $this->assertFalse($this->_form->isValid($data));}
  • Create the form class<?phpclass Application_Form_CommentForm extends Zend_Form{ public function init() { /* Form Elements & Other Definitions Here ... */ }}
  • Let’s run the test
  • Let’s put in our elements<?phpclass Application_Form_CommentForm extends Zend_Form{ public function init() { $this->addElement(text, name, array ( Label => Name, Required => true)); $this->addElement(text, mail, array ( Label => E-mail Address, Required => true)); $this->addElement(text, web, array ( Label => Website, Required => false)); $this->addElement(textarea, comment, array ( Label => Comment, Required => true)); $this->addElement(submit, post, array ( Label => Post, Ignore => true)); }}
  • Less errors?
  • Filter - Validate$this->addElement(text, name, array ( Label => Name, Required => true, Filters => array (StringTrim, StripTags), Validators => array ( new Zftest_Validate_Mwop(), new Zend_Validate_StringLength(array (min => 4, max => 50))),));$this->addElement(text, mail, array ( Label => E-mail Address, Required => true, Filters => array (StringTrim, StripTags, StringToLower), Validators => array ( new Zend_Validate_EmailAddress(), new Zend_Validate_StringLength(array (min => 4, max => 50))),));$this->addElement(text, web, array ( Label => Website, Required => false, Filters => array (StringTrim, StripTags, StringToLower), Validators => array ( new Zend_Validate_Callback(array(Zend_Uri, check)), new Zend_Validate_StringLength(array (min => 4, max => 50))),));$this->addElement(textarea, comment, array ( Label => Comment, Required => true, Filters => array (StringTrim, StripTags), Validators => array ( new Zftest_Validate_TextBox(), new Zend_Validate_StringLength(array (max => 5000))),));
  • Green, warm & fuzzy
  • You’re a winner!☑ quality code☑ tested☑ secure☑ reusable
  • Testing models
  • Testing business logic•- models contain logic tied to your business - tied to your storage - tied to your resources• no “one size fits all” solution
  • Type: data containers•- contains structured data populated through setters and getters•- perform logic tied to it’s purpose transforming data - filtering data - validating data• can convert into other data types - arrays - strings (JSON, serialized, xml, …)• are providers to other models
  • Comment Class
  • Writing model test<?phpclass Application_Model_CommentTest extends PHPUnit_Framework_TestCase{ protected $_comment; protected function setUp() { $this->_comment = new Application_Model_Comment(); parent::setUp(); } protected function tearDown() { parent::tearDown(); $this->_comment = null; } public function testModelIsEmptyAtConstruct() { $this->assertSame(0, $this->_comment->getId()); $this->assertNull($this->_comment->getFullName()); $this->assertNull($this->_comment->getEmailAddress()); $this->assertNull($this->_comment->getWebsite()); $this->assertNull($this->_comment->getComment()); }}
  • This test won’t run!
  • Create a simple model<?phpclass Application_Model_Comment{ protected $_id = 0; protected $_fullName; protected $_emailAddress; protected $_website; protected $_comment; public function setId($id) { $this->_id = (int) $id; return $this; } public function getId() { return $this->_id; } public function setFullName($fullName) { $this->_fullName = (string) $fullName; return $this; } public function getFullName() { return $this->_fullName; } public function setEmailAddress($emailAddress) { $this->_emailAddress = (string) $emailAddress; return $this; } public function getEmailAddress() { return $this->_emailAddress; } public function setWebsite($website) { $this->_website = (string) $website; return $this; } public function getWebsite() { return $this->_website; } public function setComment($comment) { $this->_comment = (string) $comment; return $this; } public function getComment() { return $this->_comment; } public function populate($row) { if (is_array($row)) { $row = new ArrayObject($row, ArrayObject::ARRAY_AS_PROPS); } if (isset ($row->id)) $this->setId($row->id); if (isset ($row->fullName)) $this->setFullName($row->fullName); if (isset ($row->emailAddress)) $this->setEmailAddress($row->emailAddress); if (isset ($row->website)) $this->setWebsite($row->website); if (isset ($row->comment)) $this->setComment($row->comment); } public function toArray() { return array ( id => $this->getId(), fullName => $this->getFullName(), emailAddress => $this->getEmailAddress(), website => $this->getWebsite(), comment => $this->getComment(), ); }}
  • We pass the test…
  • Really ???
  • Not all data from form!•- model can be populated from users through the form - data stored in the database - a webservice (hosted by us or others)• simply test it - by using same test scenario’s from our form
  • The good stuffpublic function goodData(){ return array ( array (John Doe, john.doe@example.com, http://example.com, test comment), array ("Matthew Weier OPhinney", matthew@zend.com, http://weierophinney.net, Doing an MWOP-Test), array (D. Keith Casey, Jr., Keith@CaseySoftware.com, http://caseysoftware.com, Doing a monkey dance), );}/** * @dataProvider goodData */public function testModelAcceptsValidData($name, $mail, $web, $comment){ $data = array ( fullName => $name, emailAddress => $mail, website => $web, comment => $comment, ); try { $this->_comment->populate($data); } catch (Zend_Exception $e) { $this->fail(Unexpected exception should not be triggered); } $data[id] = 0; $data[emailAddress] = strtolower($data[emailAddress]); $data[website] = strtolower($data[website]); $this->assertSame($this->_comment->toArray(), $data);}
  • The bad stuffpublic function badData(){ return array ( array (,,,), array ("Robert; DROP TABLES comments; --", , http://xkcd.com/327/,Little BobbyTables), array (str_repeat(x, 1000), , , ), array (John Doe, jd@example.com, "http://t.co/@"style="font-size:999999999999px;"onmouseover="$.getScript(http:u002fu002fis.gdu002ffl9A7)"/", exploit twitter9/21/2010), );}/** * @dataProvider badData */public function testModelRejectsBadData($name, $mail, $web, $comment){ $data = array ( fullName => $name, emailAddress => $mail, website => $web, comment => $comment, ); try { $this->_comment->populate($data); } catch (Zend_Exception $e) { return; } $this->fail(Expected exception should be triggered);}
  • Let’s run it
  • Modify our modelprotected $_filters;protected $_validators;public function __construct($params = null){ $this->_filters = array ( id => array (Int), fullName => array (StringTrim, StripTags, new Zend_Filter_Alnum(true)), emailAddress => array (StringTrim, StripTags, StringToLower), website => array (StringTrim, StripTags, StringToLower), comment => array (StringTrim, StripTags), ); $this->_validators = array ( id => array (Int), fullName => array ( new Zftest_Validate_Mwop(), new Zend_Validate_StringLength(array (min => 4, max => 50)), ), emailAddress => array ( EmailAddress, new Zend_Validate_StringLength(array (min => 4, max => 50)), ), website => array ( new Zend_Validate_Callback(array(Zend_Uri, check)), new Zend_Validate_StringLength(array (min => 4, max => 50)), ), comment => array ( new Zftest_Validate_TextBox(), new Zend_Validate_StringLength(array (max => 5000)), ), ); if (null !== $params) { $this->populate($params); }}
  • Modify setters: Id & namepublic function setId($id){ $input = new Zend_Filter_Input($this->_filters, $this->_validators); $input->setData(array (id => $id)); if (!$input->isValid(id)) { throw new Zend_Exception(Invalid ID provided); } $this->_id = (int) $input->id; return $this;}public function setFullName($fullName){ $input = new Zend_Filter_Input($this->_filters, $this->_validators); $input->setData(array (fullName => $fullName)); if (!$input->isValid(fullName)) { throw new Zend_Exception(Invalid fullName provided); } $this->_fullName = (string) $input->fullName; return $this;}
  • Email & websitepublic function setEmailAddress($emailAddress){ $input = new Zend_Filter_Input($this->_filters, $this->_validators); $input->setData(array (emailAddress => $emailAddress)); if (!$input->isValid(emailAddress)) { throw new Zend_Exception(Invalid emailAddress provided); } $this->_emailAddress = (string) $input->emailAddress; return $this;}public function setWebsite($website){ $input = new Zend_Filter_Input($this->_filters, $this->_validators); $input->setData(array (website => $website)); if (!$input->isValid(website)) { throw new Zend_Exception(Invalid website provided); } $this->_website = (string) $input->website; return $this;}
  • and commentpublic function setComment($comment){ $input = new Zend_Filter_Input($this->_filters, $this->_validators); $input->setData(array (comment => $comment)); if (!$input->isValid(comment)) { throw new Zend_Exception(Invalid comment provided); } $this->_comment = (string) $input->comment; return $this;}
  • Now we’re good!
  • Testing Databases
  • Integration Testing•- database specific functionality triggers - constraints - stored procedures - sharding/scalability• data input/output - correct encoding of data - transactions execution and rollback
  • Points of concern•- beware of automated data types auto increment sequence ID’s - default values like CURRENT_TIMESTAMP• beware of time related issues - timestamp vs. datetime - UTC vs. local time
  • The domain Model• Model object• Mapper object• Table gateway object Read more about it
  • Change our test classclass Application_Model_CommentTest extends PHPUnit_Framework_TestCasebecomesclass Application_Model_CommentTest extends Zend_Test_PHPUnit_DatabaseTestCase
  • Setting DB Testing upprotected $_connectionMock;public function getConnection(){ if (null === $this->_dbMock) { $this->bootstrap = new Zend_Application( APPLICATION_ENV, APPLICATION_PATH . /configs/application.ini); $this->bootstrap->bootstrap(db); $db = $this->bootstrap->getBootstrap()->getResource(db); $this->_connectionMock = $this->createZendDbConnection( $db, zftest ); return $this->_connectionMock; }}public function getDataSet(){ return $this->createFlatXmlDataSet( realpath(APPLICATION_PATH . /../tests/_files/initialDataSet.xml));}

  • Run Test
  • Testing Web Services
  • Web services remarks•- you need to comply with an API that will be your reference•- You cannot always make a test-call paid services per call - test environment is “offline” - network related issues
  • Example: joind.in
  • JoindIn Test<?phpclass Zftest_Service_JoindinTest extends PHPUnit_Framework_TestCase{ protected $_joindin; protected $_settings; protected function setUp() { $this->_joindin = new Zftest_Service_Joindin(); // using the test adapter for testing $client = new Zend_Http_Client(); $client->setAdapter(new Zend_Http_Client_Adapter_Test()); $this->_joindin->setClient($client); $settings = simplexml_load_file(realpath( APPLICATION_PATH . /../tests/_files/settings.xml)); $this->_settings = $settings->joindin; parent::setUp(); } protected function tearDown() { parent::tearDown(); $this->_joindin = null; }
  • JoindIn Test public function testJoindinCanGetUserDetails() { $expected = <?xml version="1.0"?><response><item><username>DragonBe</username><full_name>Michelangelo van Dam</full_name><ID>19</ID><last_login>1303248639</last_login></item></response>; $this->_joindin->setUsername($this->_settings->username) ->setPassword($this->_settings->password); $actual = $this->_joindin->user()->getDetail(); $this->assertXmlStringEqualsXmlString($expected, $actual); } public function testJoindinCanCheckStatus() { $date = new DateTime(); $date->setTimezone(new DateTimeZone(UTC));$client = $this->_joindin->getClient()->getAdapter()->setResponse($response); $expected = <?xml version="1.0"?><response><dt> . $date->format(r) . </dt><test_string>testing unit test</test_string></response>; $actual = $this->_joindin->site()->getStatus(testing unit test); $this->assertXmlStringEqualsXmlString($expected, $actual); }
  • Testing The Service
  • Euh… What?1) Zftest_Service_JoindinTest::testJoindinCanGetUserDetailsFailed asserting that two strings are equal.--- Expected+++ Actual@@ @@ <ID>19</ID>- <last_login>1303248639</last_login>+ <last_login>1303250271</last_login> </item> </response>
  • And this?2) Zftest_Service_JoindinTest::testJoindinCanCheckStatusFailed asserting that two strings are equal.--- Expected+++ Actual@@ @@<?xml version=”1.0”?><response>- <dt>Tue, 19 Apr 2011 22:26:40 +0000</dt>+ <dt>Tue, 19 Apr 2011 22:26:41 +0000</dt></response>
  • Solution is right here!
  • API = test scenarios
  • Mocking Client Adapter<?phpclass Zftest_Service_JoindinTest extends PHPUnit_Framework_TestCase{ protected $_joindin; protected $_settings; protected function setUp() { $this->_joindin = new Zftest_Service_Joindin(); // using the test adapter for testing $client = new Zend_Http_Client(); $client->setAdapter(new Zend_Http_Client_Adapter_Test()); $this->_joindin->setClient($client); $settings = simplexml_load_file(realpath( APPLICATION_PATH . /../tests/_files/settings.xml)); $this->_settings = $settings->joindin; parent::setUp(); }

  • Good implementation?
  • Controller Testing
  • When to use?•- GOOD validation of correct headers- track redirections- errors and/or exceptions- visitor flow (page 1 -> page 2, …)•NOT SO GOOD- validation of DOM elements on page- asserting (error) messages
  • Form Flow
  • REMARK•- data providers can be used to test valid data - to test invalid data• but we know it’s taken care of our model - just checking for error messages in the form
  • Setting up ControllerTest?phpclass IndexControllerTest extends Zend_Test_PHPUnit_ControllerTestCase{ public function setUp() { $this->bootstrap = new Zend_Application( APPLICATION_ENV, APPLICATION_PATH . /configs/application.ini); parent::setUp(); }…}
