clojure.test assertions

Learn clojure.test assertions in Clojure with a construct-specific explanation, a unique example, a practical boundary, and a mastery check.

12 min read • Advanced

clojure.test assertions is an atomic Clojure topic inside Polymorphism, Errors & Testing. The example below uses the actual construct named by the lesson rather than a generic placeholder.

Focus on what clojure.test assertions changes: the input, binding, control path, object state, collection, runtime effect, or language contract. Then alter one value and verify that the behavior changes for a reason specific to this feature.

Topic-specific example

clojure-08-09-clojure-test-assertions.clj
clojure Try It Live
(require '[clojure.test :refer [is]])
(is (= 4 (+ 2 2)))
Edge case / engineering note

Exercise both the success path and the failure path; verify what is caught, propagated, or cleaned up rather than only checking printed output.
