- 5. Unit testing: Testing the smallest testable parts of an application (Functions, Classes, Macros) Dave Ross | West Suburban Chicago PHP Meetup | suburbanchicagophp.org
- 6. The xUnit frameworks provide a way to automate unit tests If you automate your tests, the quality of your tests is consistent Dave Ross | West Suburban Chicago PHP Meetup | suburbanchicagophp.org
- 7. Dave Ross | West Suburban Chicago PHP Meetup | suburbanchicagophp.org Make it easy to test, and you'll do it more often. If you use version control, test before every check-in
- 8. Dave Ross | West Suburban Chicago PHP Meetup | suburbanchicagophp.org You can wrap a set of tests into a test suite A suite tests larger units of your application, even the application itself
- 9. Dave Ross | West Suburban Chicago PHP Meetup | suburbanchicagophp.org PHP itself is tested using automated tests They use a framework called phpt

- 11. Dave Ross | West Suburban Chicago PHP Meetup | suburbanchicagophp.org Let's look at a test case!
- 12. Dave Ross | West Suburban Chicago PHP Meetup | suburbanchicagophp.org <?php require_once 'PHPUnit/Framework.php'; class ArrayTest extends PHPUnit_Framework_TestCase { protected $fixture; protected function setUp() { // Create the Array fixture. $this->fixture = array(); } public function testNewArrayIsEmpty() { // Assert that the size of the Array fixture is 0. $this->assertEquals(0, sizeof($this->fixture)); } public function testArrayContainsAnElement() { // Add an element to the Array fixture. $this->fixture[] = 'Element'; // Assert that the size of the Array fixture is 1. $this->assertEquals(1, sizeof($this->fixture)); } } ?>
- 13. Dave Ross | West Suburban Chicago PHP Meetup | suburbanchicagophp.org Tests should be run against a known, fixed state called a fixture setUp() creates this state tearDown() destroys the state and puts things back the way they were
- 14. Dave Ross | West Suburban Chicago PHP Meetup | suburbanchicagophp.org Test cases are implemented as functions whose names start with the word “ test ” This example has: testNewArrayIsEmpty() testArrayContainsAnElement()
- 15. Dave Ross | West Suburban Chicago PHP Meetup | suburbanchicagophp.org Run a PHPUnit test case with the phpunit command phpunit UnitTest UnitTest.php tells PHPUnit to look for a class UnitTest in the UnitTest.php file (filename is optional)
- 16. Dave Ross | West Suburban Chicago PHP Meetup | suburbanchicagophp.org phpunit ArrayTest PHPUnit 3.3.0 by Sebastian Bergmann. .. Time: 0 seconds OK (2 tests)
- 17. Dave Ross | West Suburban Chicago PHP Meetup | suburbanchicagophp.org Can output test logs to a variety of formats : GraphViz JSON TAP XML
- 18. Dave Ross | West Suburban Chicago PHP Meetup | suburbanchicagophp.org Test suite + Exported results allows for Continuous Integration
- 19. Dave Ross | West Suburban Chicago PHP Meetup | suburbanchicagophp.org Continuous integration is a way to automatically run your test suite regularly Once a day... Once an hour... Every time someone checks in code...
