I'll invoke it with a bin/kaocha file as described in the quickstart.

#!/usr/bin/env bash

clojure -A:test -m kaocha.runner "$@"

From glancing at your setup, it does look like your namespace isn't correct. You have, in your deps, that path being src, yet, underneath that you have the structure clj/handler/view.clj, which would suggest to me that your namespace should be clj.handler.view, not handler.view, which is why the compiler can't find handler/view.clj, as it's expecting clj/handler/view.clj

in your tests.edn, you have the path correct, i.e., source-paths ["src/clj"], but in your deps.edn, you just have src.

The :test alias also has a slight error in the path, it says test/cljt rather than test/clj Unless the project will have Clojure common and ClojureScript files, I suggest simplifying the paths and removing the clj directories from under src and test directories

After adding the clj to the src path and removing the test path property the tests are now running. Thanks for your help
