protected function UnitTestBase::setUp

Sets up unit test environment.

Unlike Drupal\simpletest\WebTestBase::setUp(), UnitTestBase::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.

  // changed, since Drupal\Core\Utility\CacheArray implementations attempt to
  // write back to persistent caches when they are destructed.
