Although most core test cases are based on DrupalWebTestCase and are functional tests (exercising the web UI) we also have DrupalUnitTestCase, which executes much faster because a Drupal install does not have to be one. No environment is provided to a test case based on DrupalUnitTestCase; it must be entirely self-contained.
