The document discusses CodeIgniter's internal unit testing capabilities and the importance of unit testing for consistent validation and error reduction during code upgrades. It introduces the CodeIgniter unit test library and provides examples of how to set up and run unit tests, including integration with the Toast testing suite for enhanced testing capabilities. Additionally, it outlines best practices for creating effective tests and hints at future content related to PHPUnit integration.

- 5. What to consider when writing your Unit TestWhat am I testing?What should I be expecting to happen?Does this Test Fail?Does this Test cover everything in the class / function?

- 10. Toast Can Test Youhttp://ds.albert-rosa/test/Blog
- 11. Getting Toasty..Toast is another unit testing suite for Code Igniter Specifically. It was designed to intergrade perfectly. Allowing more points of testing and a more defined way of testing closely related to jUnit.You can get more information at http://jensroland.com/projects/toast/.INSTRUCTIONSDownload and unzip the filesCreate two new folders:* /app/controllers/test* /app/views/testMove the two controller files and the example test class to the first folder, and the three view files to the second
- 12. Toast Test …require_once(APPPATH . '/controllers/test/Toast.php');class Example_tests extends Toast{ function Example_tests(){parent::Toast(__FILE__); // Load any models, libraries etc. you need here $this->load->model('blogmodel'); } /** * OPTIONAL; Anything in this function will be run before each test * Good for doing cleanup: resetting sessions, renewing objects, etc. */ function _pre() {} /** * OPTIONAL; Anything in this function will be run after each test * I use it for setting $this->message = $this->My_model->getError(); */ function _post() {}
- 13. function test_simple_addition(){ $var = 2 + 2;$this->_assert_equals($var, 4);}function test_that_fails() {$a = true;$b = $a;$this->_assert_true($a); // true$this->_assert_false($b); // false$this->_assert_equals($a, $b); // true }function test_or_operator(){$a = true;$b = false;$var = $a || $b;$this->_assert_true($var);$this->message = '$a || $b';}public function test_model(){ $result = $this->blogmodel->get_last_ten_entries(); $this->_assert_not_empty($result); $this->_assert_equals($result[0]->title,'Hello World!', 'blog title first Record');} }?>
- 14. ToastAll Toast Test must be within the Test Folder with all the Toast filesAll Toast Test must include the Toast.phpAll Toast Test classes must extend ToastTo Run and View the Toast Results, go to the test folder in the browser and go to the class you want to runhttp://www.example.com/test/class_toastedYou can all go to http://www.example.com/test/toast_all
- 15. Things to Keep in mindA Test is only as good as you create it to beTry to think of every possible scenarioThe test must be able to failMany testers find that the test is always passing and cannot make the test fail… there is a something wrong with the test.Don’t just test your work but test the framework too!Every framework has some pit fall or an area where the the contributors over looked… it happens .. Give back and submit your “bugs” and fail points
- 16. What’s Coming with Unit Testing Part 2 For the second part of this two part series we will talk aboutPHPUnitPHPUnit and CodeIgniterAnt scriptingAutomating PHPUnit Test with Ant Q & AGot a question…Got a real world problem…Got an imaginary world problem…
