Hi Eric,

We had that discussion some weeks ago regarding the WARN status of a
test when the file hash is not provided for the fetch call. We agreed
that a WARN is not a harmful status, and it would be okay.

When we got the request to add the message regarding a missing hash of
a downloaded file, we concluded that it would not make sense to set it
like a normal message in the logs because no one would open the logs
and see the message if the test succeed.

If you think a WARN may be considered a harmful status, let us know,
and we can try to adjust it so that users see the message when a hash
is not provided without setting the test status as WARN.

On the other hand, you can always add the hash if you have access to it.

I hope it helps somehow,

Willian
