 If you want certain tasks to run in check mode always, or never, regardless of whether you run the playbook with or without ``--check``, you can add the ``check_mode`` option to those tasks:
 
-  - To force a task to run in check mode, even when the playbook is called without ``--check``, set ``check_mode: yes``.
-  - To force a task to run in normal mode and make changes to the system, even when the playbook is called with ``--check``, set ``check_mode: no``.

-Running single tasks with ``check_mode: yes`` can be useful for testing Ansible modules, either to test the module itself or to test the conditions under which a module would make changes. You can register variables (see :ref:`playbooks_conditionals`) on these tasks for even more detail on the potential changes.
