Unit Testing PHP apps with PHPUnit

Let’s talk about tes6ng

��3

Excuses not to test

• No 6me • Not in budget • We don’t know how -‐ valid and honest answer

• We add unit tests a@er finish project -‐ right, like that’s going to happen

• …

��4

No excuses

��5

Unit tes6ng is fun and easy!

• When you write code • You already test in your head • Write out these test(s) • And protect your code base

��6

How to get started?

��7

project/ src/ Utexamples/ Calculator.php autoload.php tests/ Utexamples/ CalculatorTest.php

My example code

• Get this example from GitHub -‐ hQps://github.com/in2it/Utexamples

��8

<?php !namespace Utexamples; !!/** ! * Class that allows us to make all sorts of calculations ! */ !class Calculator !{ ! protected $_value = 0; !! /** ! * Adds the current value by one ! * ! * @return int The value from this method ! */ ! public function addByOne() ! { ! $this->_value++; ! return $this->_value; ! } !}

Simple example class• Add by one -‐ adds the current value by one

��9

Our unit test<?php !namespace Utexamples; !!Class CalculatorTest extends \PHPUnit_Framework_TestCase !{ ! public function testCalculatorCanAddByOne() ! { ! $calculator = new Calculator(); ! $result = $calculator->addByOne(); ! $this->assertSame(1, $result); ! } !}

��10

My autoloader<?php !!/** ! * Simple autoloader that follow the PHP Standards Recommendation #0 (PSR-0) ! * @see https://github.com/php-fig/fig-standards/blob/master/accepted/PSR-0.md for more informations. ! * ! * Code inspired from the SplClassLoader RFC ! * @see https://wiki.php.net/rfc/splclassloader#example_implementation ! */ !spl_autoload_register(function($className) { ! $className = ltrim($className, '\\'); ! $fileName = ''; ! $namespace = ''; ! if ($lastNsPos = strripos($className, '\\')) { ! $namespace = substr($className, 0, $lastNsPos); ! $className = substr($className, $lastNsPos + 1); ! $fileName = str_replace(! '\\', DIRECTORY_SEPARATOR, $namespace) . DIRECTORY_SEPARATOR; ! } ! $fileName = __DIR__ . DIRECTORY_SEPARATOR . $fileName . $className . '.php'; ! if (file_exists($fileName)) { ! require $fileName; !! return true; ! } !! return false; !});

A lot of parameters!

• Easily possible to make mistakes • Every developer might use different params • Not easy for (semi-‐)automated tes6ng -‐ Using IDE for running unit tests

��13

Filtering & Valida6on

��29

Libs you can use

• Zend Framework 1: Zend_Filter_Input • Zend Framework 2: Zend\InputFilter • Symfony: Symfony\Component\Validator • Aura: Aura\Framework\Input\Filter • Lithium: lithium\u6l\Validator • Laravel: App\Validator

��30

Modify our Product class<?php !namespace Utexamples\Model; !!class Product extends ModelAbstract !{ ! ...! /** ! * @var \Zend_Filter_Input The filter/validator for this Product ! */ ! protected $_inputFilter; !! /** ! * @var bool The validation of data for this Product ! */ ! protected $_valid; !! /** ! * Helper class to create filter and validation rules ! * ! * @access protected ! */ ! protected function _createInputFilter() ! { ! ...! } ! ...!}

��31

_createInputFilter() protected function _createInputFilter() ! { ! $filters = array ( ! 'productId' => array('Int'), ! 'code' => array ('StripTags', 'StringTrim', 'StringToUpper'), ! 'title' => array ('StripTags', 'StringTrim'), ! 'description' => array ('StripTags', 'StringTrim'), ! 'image' => array ('StripTags', 'StringTrim','StringToLower'), !

'price' => array ( ! 'Float', ! array ('GreaterThan', array ('min' => 0, 'inclusive' => true)), ! ), ! ); ! $this->_inputFilter = new \Zend_Filter_Input($filters, $validators); ! }

��32

Modify your seQers /** ! * Set the product code for this Product ! * ! * @param string $code ! * @return Product ! */ ! public function setCode($code) ! { ! $this->_inputFilter->setData(array ('code' => $code)); ! if ($this->_inputFilter->isValid('code')) { ! $this->_code = $this->_inputFilter->code; ! $this->setValid(true); ! } else { ! $this->setValid(false); ! } ! return $this; ! }

��33

Modify your seQers /** ! * Set the product code for this Product ! * ! * @param string $code ! * @return Product ! */ ! public function setCode($code) ! { ! $this->_inputFilter->setData(array ('code' => $code)); ! if ($this->_inputFilter->isValid('code')) { ! $this->_code = $this->_inputFilter->code; ! $this->setValid(true); ! } else { ! $this->setValid(false); ! } ! return $this; ! }

��33

$this->_inputFilter->setData(array ('code' => $code)); ! if ($this->_inputFilter->isValid('code')) { ! $this->_code = $this->_inputFilter->code; ! $this->setValid(true); ! } else { ! $this->setValid(false); ! } ! return $this;

Using dataproviders again public function badDataProvider() ! { ! return array ( ! array ( ! 1, '', '', '', '', 0, ! '0000-00-00 00:00:00', ! '0000-00-00 00:00:00', ! ), ! array ( ! 1, ! '!@#$%^@^&*{}[]=-/\'\\', 'Test Product 1', ! 'This is a full description of test product 1', 'image.png', ! 123.95, '2013-11-20 16:00:00', '2013-11-20 17:00:00', ! ), ! array ( ! 1, '\' OR 1=1; --', 'Test Product 1', ! 'This is a full description of test product 1', 'image.png', ! 123.95, '2013-11-20 16:00:00', '2013-11-20 17:00:00', ! ), ! ); ! }

��34

And now we test for valid data /** ! * @dataProvider badDataProvider ! */ ! public function testProductRejectsBadData( ! $productId, $code, $title, $description, $image, $price, $created, $modified ! ) ! { ! $data = array ( ! 'productId' => $productId, ! 'code' => $code, ! 'title' => $title, ! 'description' => $description, ! 'image' => $image, ! 'price' => $price, ! 'created' => $created, ! 'modified' => $modified, ! ); !! $product = new Product($data); ! $this->assertFalse($product->isValid()); ! }

��35

And now we test for valid data /** ! * @dataProvider badDataProvider ! */ ! public function testProductRejectsBadData( ! $productId, $code, $title, $description, $image, $price, $created, $modified ! ) ! { ! $data = array ( ! 'productId' => $productId, ! 'code' => $code, ! 'title' => $title, ! 'description' => $description, ! 'image' => $image, ! 'price' => $price, ! 'created' => $created, ! 'modified' => $modified, ! ); !! $product = new Product($data); ! $this->assertFalse($product->isValid()); ! }

��35

$product = new Product($data); ! $this->assertFalse($product->isValid());

Everybody happy

��50

Some downsides

• Tes6ng databases takes 6me -‐ create a real database connec6on

-‐ reini6alise the database (load schema, truncate tables)

-‐ load ini6al state before test (with each test)

-‐ execute on the database

-‐ compare expected result with actual result

��51

We can do beQer!

��52

Mock objects

• They replace an object for tes6ng -‐ a class with all methods

-‐ a class with a single method

• Since they replace “expansive” connec6ons -‐ databases

-‐ web services

-‐ file systems

• Are quicker and more reliable to test -‐ once you got everything set up

Why the extra work?

• Your databases are fully tested, no need to do it yourself again

• The connec6ons are expensive and delay your tests

• Your tes6ng code that needs to handle the data it gets, no maQer where it gets it
