Unclear message in failed tests "to rerun pass --lib"

[StefanSalewski]

I was wondering about that text already when I saw it first in the book more than one year ago, and have still no idea.

https://doc.rust-lang.org/book/ch11-01-writing-tests.html#checking-for-panics-with-should_panic

What is these

"error: test failed, to rerun pass --lib"

I just tested, it is not a typo in the book, it is really printed when running "cargo test".

Well perhaps my question is a bit stupid, I am not a native English speaker :-)
