class DrupalUnitTestCase in SimpleTest 6.2

Same name and namespace in other branches

  2. 7 drupal_web_test_case.php \DrupalUnitTestCase

Test case for Drupal unit tests.

These tests can not access the database nor files. Calling any Drupal function that needs the database will throw exceptions. These include watchdog(), module_implements(), module_invoke_all() etc.
