Looks good for me I made a suggestion for the url error. PS is a NEWS update needed?

Noticed a bunch more, now all standardized. Let's see if the checks pass.

@peterdesmet I fixed some of the testing errors any objection merging this?

I think the decrease in coverage is mostly due to different formatting and error message spread over more lines
