clojure.test assertion extensions
\When running clojure.test based tests through Kaocha, some of the behavior is a little different. Kaocha tries to detect certain scenarios that are likely mistakes which make a test pass trivially, and turns them into errors so you can investigate and see what's up.
Kaocha will also render failures differently, and provides extra multimethods to influence how certain failures are presented.
Detecting missing assertions(ns sample-test
(:require [clojure.test :refer :all]))
(deftest my-test
(= 4 5))
When I run bin/kaocha
Then the output should contain:
FAIL in sample-test/my-test (sample_test.clj:4)
Test ran without assertions. Did you forget an (is ...)?
=
(ns sample-test
(:require [clojure.test :refer :all]))
(deftest my-test
(is (= 4) 5))
When I run bin/kaocha
Then the output should contain:
FAIL in sample-test/my-test (sample_test.clj:5)
Equality assertion expects 2 or more values to compare, but only 1 arguments given.
Expected:
(= 4 arg2)
Actual:
(= 4)
1 tests, 1 assertions, 1 failures.
(ns sample-test
(:require [clojure.test :refer :all]))
(defn my-fn []
{:xxx [1 2 3]
:blue :red
"hello" {:world :!}})
(deftest my-test
(is (= {:xxx [1 3 4]
"hello" {:world :?}}
{:xxx [1 2 3]
:blue :red
"hello" {:world :!}})))
When I run bin/kaocha
Then the output should contain:
FAIL in sample-test/my-test (sample_test.clj:10)
Expected:
{"hello" {:world :?}, :xxx [1 3 4]}
Actual:
{"hello" {:world -:? +:!}, :xxx [1 +2 3 -4], +:blue :red}
1 tests, 1 assertions, 1 failures.
Can you improve this documentation? These fine people already did:
