.toHaveProperty() does not distinguish between any and never. See the link above.

It sound like never should not have any properties. Might be I missed something.

@mrazauskas Technically both keyof never and keyof any resolve to string | number | symbol. Not sure if it would be the best idea to stray away from TypeScript's intended behavior but you're right. Semantically it doesn't make sense. It seems like keyof never should be never. Not sure what the best approach here would be to be honest.
