The are macro is also part of the clojure.test library. It allows you to make multiple assertions against a template.

For example:

(are [x y] (= x y)  
   4 (+ 2 2)
   8 (* 2 4))
=> true

Here, (= x y) acts as a template which takes each argument and creates an is assertion out of it.

This expands to multiple is assertions:

(do 
  (is (= 4 (+ 2 2)))
  (is (= 8 (* 2 4))))
