DrupalWebTestCase

Creates a fresh installation of Drupal with tables in a prefix simpletest* and has a virtual browser.

DrupalWebTestCase

class ExampleTestCase extends DrupalWebTestCase {

  public static function getInfo() {
    return array(
      'name' => 'Name',
      'description' => 'Description',
      'group' => 'Group',
    );
  }

  public function setUp() {
    parent::setUp('example_module');
  }
}
          

DrupalUnitTestCase

Doesn't create tables, and is lighter and faster.

DrupalUnitTestCase

class ExampleUnitTestCase extends DrupalUnitTestCase {

  public static function getInfo() {
    return array(
      'name' => 'Name',
      'description' => 'Description',
      'group' => 'Group',
    );
  }

  public function setup() {
    drupal_load('module', 'example_module');
    parent::setUp();
  }
}
