Right, but that is true for other tests as well and we are not
expecting to face this/other errors. I think keeping it simple and
similar to other tests seems enough for this case.

Thanks, I'll push this in a day or two unless I see any other

mentioned by Euler in his initial email, this is not required from v11
onwards due to a different solution for this problem via commit
325f2ec555.
