The test file looks like (ns alphabet-cipher.coder-test (:require [clojure.test :refer :all] [alphabet-cipher.coder :refer :all])) (deftest test-encode (testing "can encode a message with a secret keyword" (is (= "hmkbxebpxpmyllyrxiiqtoltfgzzv" (encode "vigilance" "meetmeontuesdayeveningatseven"))) (is (= "egsgqwtahuiljgs" (encode "scones" "meetmebythetree")))))

running the test at point with C-c C-t t does work

any idea why the run loaded tests isn't working?

also C-c C-t n does work

it could be because the test dir isn't in your classpath? It's a common pitfall, especially for deps.edn users

yep that was it, the project was assuming I would run the tests in the CLI, thanks for the tip
