ProjectStatus

A set of classes that aims to facilitate the preparation and writing tests using PHPUnit for applications built with Laravel 4.

Features

Current:

  • Pretend mail sending to speed up tests
  • Simpler and flexible controller and request testing
  • Specific assertions for controller testing
  • Front-end testing with Selenium (with selenium integration)
  • Specific assertions for front-end testing
  • Simple to use!

Quick start

Required setup

In the require key of composer.json file add the following

"zizaco/testcases-laravel": "dev-master"

Run the Composer update comand

$ composer update

Testing models and libraries

To write tests for models and other classes, simply extend the Zizaco\TestCases\TestCase. For example:

<?php

class StuffTest extends Zizaco\TestCases\TestCase
{
    /**
     * Clean collection between every test
     */
    public function setUp()
    {
        foreach( Stuff::all() as $s ) { $s->delete(); }
        parent::setUp(); // Don't forget this if you overwrite the setUp() method
    }

    /* Your tests here :) */
}

To test a non-model class:

<?php

use Mockery as m;

class StuffRepositoryTest extends Zizaco\TestCases\TestCase
{

    public function testShouldCreateNew()
    {
        $repo = new StuffRepository;

        /* Something and some assertion */
    }

    /* Other tests */
}

Testing controllers

To write test for controllers, extend the Zizaco\TestCases\ControllerTestCase. For example

<?php

use Mockery as m;

class StuffsControllerTest extends Zizaco\TestCases\ControllerTestCase
{
    /**
     * Create action should always return 200
     *
     */
    public function testShouldCreate(){
        // Make request to action
        $this->requestAction('GET', 'StuffsControllerTest@create');

        // Asserts if the response code is 200
        $this->assertRequestOk();
        // $this->assertStatusCode( 200 ); // Is the same as assertRequestOk()
    }

    /**
     * Store action should redirect to index if success
     *
     */
    public function testShouldStoreValidContent(){

        // Mocks the StuffRepository to make sure that the storeNew
        // method will be called at least once
        $stuffRepo = m::mock(new StuffRepository);
        $stuffRepo->shouldReceive('storeNew')->once()->passthru();
        App::instance("StuffRepository", $stuffRepo);

        $input = array('name'=>'Something nice', 'slug'=>'something_nice');

        // Method chaining ;)
        $this->withInput($input)->requestAction('POST', 'StuffsController@store');

        // Asserts if the page was redirected to the correct place
        $this->assertRedirection(URL::action('StuffsController@index'));

        // Asserts if the session key "flash" has "success" word somewhere
        $this->assertSessionHas('flash','success');
    }

    /* Other tests and stuff */
}

Front-end / Integration tests

TestCases-Laravel makes integration tests really easy to write. First of all, download the Selenium Server (formerly the Selenium RC Server) and place it in the .selenium directory in your home. For example: ~/.selenium/selenium-server-standalone-7.7.7.jar. The IntegrationTestCase will automatically starts the server, start the php build in web server and run the tests.

To write an integration test, extend the Zizaco\TestCases\IntegrationTestCase class. Its also a good idea to use Selenium\Locator as l; on the beginning of the file in order to easly use the locators

<?php

use Selenium\Locator as l;

class ManageContentTest extends Zizaco\TestCases\IntegrationTestCase
{

    public function testCreateAStuff()
    {
        $this->browser
            ->open(URL::action('StuffController@index'))    // Visits the 'stuff' index
            ->click(l::id('btn-create-new-stuff'))          // Click in the new button
            ->waitForPageToLoad(1000)                       // Wait for the page to load
            ->type(l::IdOrName('name'), 'Something nice')   // Fill name
            ->type(l::IdOrName('slug'), 'something_nice')   // Fill slug
            ->select(l::IdOrName('importance'), 'High')     // Select a value in a selector/combobox
            ->click(l::css('.btn-primary'))                 // Click in the button
            ->waitForPageToLoad(1000);                      // Wait for page to load

        // Asserts if at the end the user is at the stuff index again
        $this->assertLocation( URL::action('StuffController@index') );

        // Asserts if inside the element #stuff-index there is the text "Something nice"
        // what means that the "stuff" has been created sucessfully :)
        $this->assertElementHasText(l::id('stuff-index'), 'Something nice');
    }

    /* Other fancy tests */
}

Usage in detail

Zizaco\TestCases\TestCase:

  1. An alternative to the default TestCase that comes in the app/tests directory
  2. Simply loads up the application in the setUp() method. This permits that your application is ready for each test
  3. Useful to test Models, Libraries, Repositories and other classes that are not controllers.

Zizaco\TestCases\ControllerTestCase:

  1. Build on top of the Zizaco\TestCases\TestCase, this class aims to facilitate the writing of controller tests.
  2. Thought method chaining, you will be able to write requests in a simple and legible way: $this->withInput($someArray)->requestUrl($url)->assertRedirection($otherUrl);
  3. Contains a set of custom assertions (assertStatusCode, assertRequestOk, assertRedirection, assertSessionHas, assertBodyHasHtml, assertBodyHasText) that helps you to evaluate if your controllers are working properly.

Zizaco\TestCases\IntegrationTestCase:

  1. Build on top of the Zizaco\TestCases\TestCase, this class aims to facilitate the writing of tests using Selenium.
  2. Checks if the Selenium server is running in the port 4444. If not, tries to find and run a selenium .jar file within the .selenium directory in your home path.
  3. Uses the alexandresalome/PHP-Selenium to interact with selenium. So these are the commands that you will be able to use and these are the possible locator options.

Troubleshooting

PHP Fatal error: Class 'Something' not found in your/app/directory/some/File.php on line 20

If you overwrite the setUp() method in your test, make sure to call parent::setUp():

public function setUp(){

    parent::setUp() // Don't forget this

    // Your stuff
}

Error: Selenium not found. Please run the selenium server (in port 4444) or place the selenium .jar file in the '.selenium'

Means that the selenium server cannot be found. Zizaco\TestCases\IntegrationTestCase will check if the Selenium server is running in the port 4444. If not, tries to find and run a selenium .jar file within the .selenium directory in your home path.

You can download the Selenium Server (formerly the Selenium RC Server) and place it in the .selenium directory in your home, for example: ~/.selenium/selenium-server-standalone-7.7.7.jar to run the integration tests properly.
