I went and looked around a bit. Is this what you're referring to?

(require tests/eli-tester)

(test
 #t
 (< 1 2)
 (+ 1 2) => 3
 (quotient/remainder 10 3) => (values 3 1)
 (car '()) =error> "expects argument of type")

Very compact and avoids the problem of "what comes first" that I usually
have with other frameworks :-)

Thanks for pointing that one out.
