14. A little test

15. Who created PHPUnit and is now project lead? A. Chris Hartjes B. Sebastian Bergmann C. Stefan Priepsch

16. With PHPUnit you can…? A. Test the smallest functional piece of code (unit) B. Test integrations with a database (integration) C. Test automated acceptance testing with Selenium D. All of the above E. None of the above

17. An assertion is…? A. Verifying that an expected value matches the result of a process? B. Verifying that a process produces results C. A transformation of a value

18. Assertion • is a true/false statement • to match an expectation • with the result of functionality under test

19. Available assertions • assertArrayHasKey() • assertArraySubset() • assertClassHasAttribute() • assertClassHasStaticAttribute() • assertContains() • assertContainsOnly() • assertContainsOnlyInstancesOf() • assertCount() • assertEmpty() • assertEqualXMLStructure() • assertEquals() • assertFalse() • assertFileEquals() • assertFileExists() • assertGreaterThan() • assertGreaterThanOrEqual() • assertInstanceOf() • assertInternalType() • assertJsonFileEqualsJsonFile() • assertJsonStringEqualsJsonFile() • assertJsonStringEqualsJsonString() • assertLessThan() • assertLessThanOrEqual() • assertNull() • assertObjectHasAttribute() • assertRegExp() • assertStringMatchesFormat() • assertStringMatchesFormatFile() • assertSame() • assertStringEndsWith() • assertStringEqualsFile() • assertStringStartsWith() • assertThat() • assertTrue() • assertXmlFileEqualsXmlFile() • assertXmlStringEqualsXmlFile() • assertXmlStringEqualsXmlString()

20. Available assertions • assertArrayHasKey() • assertArraySubset() • assertClassHasAttribute() • assertClassHasStaticAttribute() • assertContains() • assertContainsOnly() • assertContainsOnlyInstancesOf() • assertCount() • assertEmpty() • assertEqualXMLStructure() • assertEquals() • assertFalse() • assertFileEquals() • assertFileExists() • assertGreaterThan() • assertGreaterThanOrEqual() • assertInstanceOf() • assertInternalType() • assertJsonFileEqualsJsonFile() • assertJsonStringEqualsJsonFile() • assertJsonStringEqualsJsonString() • assertLessThan() • assertLessThanOrEqual() • assertNull() • assertObjectHasAttribute() • assertRegExp() • assertStringMatchesFormat() • assertStringMatchesFormatFile() • assertSame() • assertStringEndsWith() • assertStringEqualsFile() • assertStringStartsWith() • assertThat() • assertTrue() • assertXmlFileEqualsXmlFile() • assertXmlStringEqualsXmlFile() • assertXmlStringEqualsXmlString()

21. Example usage Assertions // Asserting a value returned by $myClass->myMethod() is TRUE $this->assertTrue($myClass->myMethod()); // Asserting that a string matches type and value of $myClass->toString() $this->assertSame('my string', $myClass->toString()); // Asserting that the value matches $myClass- >addOne(0), type check not necessary $this->assertEquals('1', $myClass->addOne(0)); // Assserting that the result of $myClass->getBirthday()->format('Y') // is greater than the expected value $this->assertGreaterThan(1900, $myClass->getBirthday()->format('Y')); // Asserting a value is NULL with a specified error message $this->assertNull( $myClass->getProperty(), 'When instantiating MyClass the property value should be NULL but is ' . $myClass->getProperty() );

22. Annotations • Provide automatic features • to execute arbitrary functionality • without having to create logic

23. Available annotations • @author • @after • @afterClass • @backupGlobals • @backupStaticAttributes • @before • @beforeClass • @codeCoverageIgnore* • @covers • @coversDefaultClass • @coversNothing • @dataProvider • @depends • @expectedException • @expectedExceptionCode • @expectedExceptionMessage • @expectedExceptionMessageRegExp • @group • @large • @medium • @preserveGlobalState • @requires • @runTestsInSeparateProcesses • @runInSeparateProcess • @small • @test • @testdox • @ticket • @uses

24. @group <?php class OrderTest extends PHPUnit_Framework_TestCase { /** * @group Order */ public function testCanCreateOrder() { // ... test logic goes here } /** * @group Order * @group BUG-1234 */ public function testOrdersCanNotContainSoldProducts() { // ... test logic goes here } }

25. How to use @group # Run phpunit only against tests for the Order module ./vendor/bin/phpunit --group Order # Run phpunit for all tests except for the Order module ./vendor/bin/phpunit --exclude-group Order

26. @dataProvider <?php class OrderTest extends PHPUnit_Framework_TestCase { public function badDataProvider() { return [ [0, 0, 0], // we don't accept ID's less or equal than 0 ['', new stdClass(), []], // only integer and float values [null, null, null], // no NULL values allowed ]; } /** * @dataProvider badDataProvider */ public function testAddProductToOrder($orderId, $productId, $price) { $order = new Order(); $result = $order->addProductToOrder($orderId, $productId, $price); $this->assertFalse($result); } }

27. @expectedException <?php class OrderTest extends PHPUnit_Framework_TestCase { /** * @expectedException InvalidArgumentException * @expectedExceptionMessage The order ID cannot be null */ public function testAddProductToOrder() { $orderId = null; $productId = null; $price = null; $order = new Order(); $result = $order->addProductToOrder($orderId, $productId, $price); $this->fail('Expected exception was not thrown'); } }

41. Composer PHPUnit ./vendor/bin/phpunit Phar PHPUnit php phpunit.phar

42. Exercise 0.0 • What will happen when you run PHPUnit now? • Checkout branch ex-0.0 git checkout -b ex-0.0 origin/ex-0.0 php composer.phar dump-autoload • Run PHPUnit

43. Let’s write our ﬁrst test <?php namespace In2itTestWorkshopCtsr; use In2itWorkshopCtsrSampleClass; class SampleClassTest extends PHPUnit_Framework_TestCase { public function testSomethingReturnsGreeting() { $sampleClass = new SampleClass(); $this->assertSame( 'Hello World!', $sampleClass->doSomething() ); } }

45. Error? Got Error? error: Your local changes to the following files would be overwritten by checkout: composer.lock Please, commit your changes or stash them before you can switch branches. Aborting Solution git checkout -- composer.lock git checkout -b ex-0.1 origin/ex-0.1

46. Write our class <?php namespace In2itWorkshopCtsr; class SampleClass { public function doSomething() { return 'Hello World!'; } }

48. Exercise 0.3 • Test that you can provide an argument and the argument will be returned as “Hello <arg>!” • Write the test • Modify the class

49. Modifying the test class public function testSomethingReturnsArgument() { $sampleClass = new SampleClass(); $argument = 'Class'; $this->assertSame( sprintf('Hello %s!', $argument), $sampleClass->doSomething($argument) ); }

50. Modify the SampleClass <?php namespace In2itWorkshopCtsr; class SampleClass { public function doSomething($argument) { return 'Hello ' . $argument . '!'; } }

51. Update further <?php namespace In2itWorkshopCtsr; class SampleClass { public function doSomething($argument = 'World') { return 'Hello ' . $argument . '!'; } }

52. Chapter 0 What have you learned • How to install phpunit • How to configure phpunit • How to write your test first • How to modify requirements through testing • How to debug failures and fix them easily with tests

56. Schedule Manager

57. Functional requirements • Application needs to manage cron entries, where all scheduled tasks are stored in a database and written to the crontab when saved.

58. What is crontab? • A tool on UNIX-like systems to execute tasks at a certain interval • Each line contains the following items: • Minutes and/or interval • Hours and/or interval • Days of the month (DOM) and/or interval • Months and/or interval • Days of the week (DOW) and/or interval • Executable command

59. Example crontab # Minutes Hours DOM Months DOW Command # Warm up caches with new products # Every 5 minutes each day */5 * * * * /bin/sh /path/to/productCollector.sh 2>&1 # Send marketing mail to active customers # Every Monday at 9:30am 30 9 * * 1 /usr/bin/php /path/to/marketingMailSender.php 2>&1 # Clean up waste # Every day at 6am, 1pm and 5pm from Monday to Friday 0 6,13,17 * * 1-5 /bin/sh /path/to/wasteCleaner.sh 2>&1

60. Analysis • crontab = collection of entries • Each entry contains 5 assets and a command • Each asset can contain a • Wildcard (full range) • Range n-m (subset of full range) • List n,m,o • A single value n • With similar intervals (without the wildcard)

61. https://www.ﬂickr.com/photos/caveman_92223/3968354387

62. • cronmanager • collection of crontab entries • each entry contains • minutes (collection) and interval (collection) • hours (collection) and interval (collection) • days of the month (collection) and interval (collection) • months (collection) and interval (collection) • days of the week (collection) and interval (collection) • command string • each entry collection (minutes, hours, dom, months, dow) requires a range • minutes (0 - 59) • hours (0 - 23) • days of the month (1 - 31) • month (1 - 12) • days of the week (0 - 7) (0 & 7 are Sunday) • crontab is write-only, so we need to update the full crontab completely

63. <?php namespace In2itTestWorkshopCtsr; class CronManagerTest extends PHPUnit_Framework_TestCase { public function testCronManagerCanAddAnEntry() { $entry = new stdClass(); $cronman = new CronManager(); $cronman->addEntry($entry); $this->assertCount(1, $cronman); } }

64. <?php namespace In2itWorkshopCtsr; class CronManager implements Countable, Iterator { protected $stack; protected $pointer; protected $counter; public function addEntry($entry) { $this->stack[] = $entry; $this->counter++; } // Implement the Iterator and Countable methods here. // - Iterator: http://php.net/manual/en/class.iterator.php // - Countable: http://php.net/manual/en/class.countable.php public function current() {/**... */} public function next() {/**... */} public function key() {/**... */} public function valid() {/**... */} public function rewind() {/**... */} public function count() {/**... */} }

65. <?php namespace In2itTestWorkshopCtsr; use In2itWorkshopCtsrCronManager; class CronManagerTest extends PHPUnit_Framework_TestCase { public function testCronManagerCanAddAnEntry() { $entry = new stdClass(); $cronman = new CronManager(); $cronman->addEntry($entry); $this->assertCount(1, $cronman); } }

66. <?php namespace In2itTestWorkshopCtsr; use In2itWorkshopCtsrCronManager; class CronManagerTest extends PHPUnit_Framework_TestCase { public function testCronManagerCanAddAnEntry() { $entry = new stdClass(); $cronman = new CronManager(); $cronman->addEntry($entry); $this->assertCount(1, $cronman); } }

67. Exercise 1.0 • Checkout branch ex-1.0 • Create a test for the Entry class

68. Something like this… <?php namespace In2itTestWorkshopCtsr; use In2itWorkshopCtsrCronManagerEntry; class EntryTest extends PHPUnit_Framework_TestCase { public function testEntryContainsAllFields() { /** ... */ } public function testEntryCanSetEntryElements() { /** ... */ } }

69. Something like this… (2) public function testEntryContainsAllFields() { $entry = new Entry(); $this->assertCount(0, $entry->getMinutes()); $this->assertCount(0, $entry->getHours()); $this->assertCount(0, $entry->getDom()); $this->assertCount(0, $entry->getMonths()); $this->assertCount(0, $entry->getDow()); $this->assertSame('', $entry->getCommand()); }

70. Something like this… (3) public function testEntryCanSetEntryElements() { $assetCollection = $this->getMock( 'In2itWorkshopCtsrCronManagerAssetCollection' ); $entry = new Entry(); $entry->setMinutes($assetCollection); $this->assertInstanceOf( 'In2itWorkshopCtsrCronManagerAssetCollection', $entry->getMinutes() ); /* * Similar routines for Hours, Days of the Month, Months and Days of the week */ $command = $this->getMock('In2itWorkshopCtsrCronManagerCommand'); $entry->setCommand($command); $this->assertInstanceOf( 'In2itWorkshopCtsrCronManagerCommand', $entry->getCommand() ); }

71. Overview of classes (ex-1.0) ctsr-workshop/ src/ ex-1.0/ CronManager.php tests/ ex-1.0/ CronManager/ EntryTest.php CronManagerTest.php

72. Exercise 1.1 • Checkout branch ex-1.1 • Have a look at all the tests

73. Pop-quiz // Why are we using Mock objects to test functionality? $assetCollection = $this->getMock( 'In2itWorkshopCtsrCronManagerAssetCollection' ); $asset = $this->getMock( 'In2itWorkshopCtsrCronManagerAsset' ); $entry = $this->getMock( 'In2itWorkshopCtsrCronManagerEntry' );

74. Question • Are we protected against bad input? • Yes • No

75. Create some bad data public function badDataProvider() { return array ( array ('foo'), array (new stdClass()), array (array ()), array (1.50), ); }

76. And let’s test it! /** * @dataProvider badDataProvider * @covers In2itWorkshopCtsrCronManagerAsset::__construct * @covers In2itWorkshopCtsrCronManagerAsset::setValue * @covers In2itWorkshopCtsrCronManagerAsset::getValue * @expectedException InvalidArgumentException */ public function testRejectBadData($badData) { $asset = new Asset($badData); $this->fail('Expected InvalidArgumentException to be thrown'); }

77. Let’s ﬁx that! /** * @param int $value * @throws InvalidArgumentException */ public function setValue($value) { if (!is_int($value)) { throw new InvalidArgumentException( 'You've provided an invalid argument' ); } if (false === ($result = filter_var($value, FILTER_VALIDATE_INT))) { throw new InvalidArgumentException( 'You've provided an invalid argument' ); } $this->value = (int) $value; }

Let’s use the static $params = array ( 'moduleName' => 'Foo_Bar', 'minVersion' => 0, 'maxVersion' => 1, 'maxOk' => true, ); // We use a static method for this test $dependency = Dependency::requires_range( $params['moduleName'], $params['minVersion'], $params['maxVersion'], $params['maxOk'] ); // We use reflection to see if properties are set correctly $reflectionClass = new ReflectionClass('Dependency');

119. Use the reﬂection to assert // Let's retrieve the private properties $moduleName = $reflectionClass->getProperty('module_name'); $moduleName->setAccessible(true); $minVersion = $reflectionClass->getProperty('version_min'); $minVersion->setAccessible(true); $maxVersion = $reflectionClass->getProperty('version_max'); $maxVersion->setAccessible(true); $maxOk = $reflectionClass->getProperty('compare_max'); $maxOk->setAccessible(true); // Let's assert $this->assertEquals($params['moduleName'], $moduleName->getValue($dependency), 'Expected value does not match the value set’); $this->assertEquals($params['minVersion'], $minVersion->getValue($dependency), 'Expected value does not match the value set’); $this->assertEquals($params['maxVersion'], $maxVersion->getValue($dependency), 'Expected value does not match the value set’); $this->assertEquals('<=', $maxOk->getValue($dependency), 'Expected value does not match the value set');
