2. 7 drupal_web_test_case.php \DrupalUnitTestCase::setUp()

Sets up unit test environment.

Unlike DrupalWebTestCase::setUp(), DrupalUnitTestCase::setUp() does not install modules because tests are performed without accessing the database. Any required files must be explicitly included by the child class setUp() method.

  // Create test directory.
  $public_files_directory = $this->originalFileDirectory . '/simpletest/' . substr($this->databasePrefix, 10);

  // If locale is enabled then t() will try to access the database and
  // subsequently will fail as the database is not accessible.
