Tests
=====
Tests succeeded/failed
-----------------------
Prior to Ansible version 2.4, a task return code of ``rc`` would override a return code of ``failed``. In version 2.4, both ``rc`` and ``failed`` are used to calculate the state of the task. Because of this, test plugins ``succeeded``/``failed``` have also been changed. This means that overriding a task failure with ``failed_when: no`` will result in ``succeeded``/``failed`` returning ``True``/``False``. For example:
- command: /bin/false
register: result
failed_when: no
- debug:
msg: 'This is printed on 2.3'
when: result|failed
- debug:
msg: 'This is printed on 2.4'
when: result|succeeded
- debug:
msg: 'This is always printed'
when: result.rc != 0
As we can see from the example above, in Ansible 2.3 ``succeeded``/``failed`` only checked the value of ``rc``.
