lgtm thanks @alamb
btw what do you think about adding a mandatory description on the test query and eventually output it?

Thanks @comphead -- I am not quite sure what you mean

Do you mean require a comment on each query that explains what is expected? It sounds reasonable to me, though if we aren't careful we'll end up with comments like # ensure correct output which probably don't add much value

composing a correct description can be part of review.

I agree this would be great. I am just wondering how to make it happen -- if the review requires human intervention anyways, I am not sure automation will help 🤔
