Extending Classes

You may want to extend the classes for your Drupal website. For example you may want to add a method that can be shared by all end to end tests, client, etc.

1. Place your extended classes in the src directory of this project like so. Place it in a folder that is namespaced with a logical name related to your project.

   .
   └── src
       ├── DrupalTest
       │   ├── ...
       └── module_name
           ├── ClientTestBase.php
           ├── EndToEndTestBase.php
           ├── KernelTestBase.php
           └── UnitTestBase.php
   

2. Make sure your classes do extend the parent:

   <?php
   
   namespace Drupal\Tests\module_name;
   
   use \AKlump\DrupalTest\ClientTestBase as Parent;
   
   abstract class ClientTest extends Parent { 
     ... 
   

3. Add your namespace to the autoloader in composer.json so your extended classes can be located.

   {
       "autoload": {
           "psr-4": {
               "AKlump\\": "src",
               "Drupal\\Tests\\module_name\\": "src/module_name"
           }
       }
   }
   

4. composer dumpautoload

5. Now create your test classes using your extended base class instead, e.g.,

   <?php
   
   namespace Drupal\Tests\module_name\Metrics;
   
   use Drupal\Tests\module_name\ClientTestBase;
   
   /**
    * Client coverage for Curriculum.
    *
    * @group module_name
    * @SuppressWarnings(PHPMD.StaticAccess)
    * @SuppressWarnings(PHPMD.TooManyPublicMethods)
    */
   class CurriculumClientTest extends ClientTestBase { 
     ...
