Is there any clojure.test "plugin" providing a nice, visual, colorful diff when (is (= complex-data actual)) fails rather than a single long line?

There are quite a few libraries that extend clojure.test like that. Paul Stadig's Humane Test Output is probably my favorite.

nice!

I've been really enjoying kaocha ( https://cljdoc.org/d/lambdaisland/kaocha ) : here's an example output https://clojureverse.org/uploads/default/original/2X/2/2a48ba2fa4906670fcfdff8c74affb2fc7eebcc7.png
