/**
 * FIXME - Add test description.
 *
 * Tips:
 *  - With HookInterface, you may implement CiviCRM hooks directly in the test class.
 *    Simply create corresponding functions (e.g. "hook_civicrm_post(...)" or similar).
 *  - With TransactionalInterface, any data changes made by setUp() or test****() functions will
 *    rollback automatically -- as long as you don't manipulate schema or truncate tables.
 *    If this test needs to manipulate schema or truncate tables, then either:
 *       a. Do all that using setupHeadless() and Civi\Test.
 *       b. Disable TransactionalInterface, and handle all setup/teardown yourself.
