assert vs fail

[S C Rigler]

Is there any advantage to using the assert module vs the fail module to bail out of a play if an expected condition isn't met?

The outcome is the same, but they work opposite way

- fail:
msg="Hello"
when: myvar == True

- assert:
that: myvar == True

If myvar is True the fail will stop the play and the assert will continue the play.
And if myvar is False the opposite will happen.

I don think there's a technical advantage, but the concepts are different:

* use assert for checking against abnormal conditions, like a malformed or missing input, missing file, that should never happen in the normal flow of your playbook.

 * use fail for aborting the playbook on operations that can meaningfully fail and that you have an idea what's happening
