Personally I'm used to seeing something like this:

"All tests passed"

or:

"123/123 tests passed"

The terminology I'm used to is that a test either passed or fails - I
haven't encountered a test framework before that talks about expected
failure. The concept makes sense but I guess it can confuse the uninitiated.

Maybe something like the following would be a decent compromise:

"123/123 tests ran as expected"
