missing-test-assertions

Library for checking absence of assertions in clojure.test tests.

Usage

Require missing.test.assertions in your test namespace(s).

Note that in a-test no assertions are made, but another-test has one assertion. So we expect a warning only about a-test.

(ns foo.core-test
  (:require [clojure.test :refer [deftest testing is]]
            [missing.test.assertions]))

(deftest a-test
  (testing "..."
    1))

(deftest another-test
  (testing (is 1)))

When executing the tests, the following warning will get printed to *err*:

WARNING: no assertions made in test a-test

Notes

• This library works with Clojure and ClojureScript.
• When registering your own clojure.test/report :begin-test-var and :end-test-var hooks, call missing.test.assertions/register! afterwards. This will redefine the missing.test.assertions hooks while your hooks keep working.

Test

JVM

lein test

or

clj -A:test

Node

script/test/node
