cljs repl "document is not defined" error
Description :octocat:
Running kaocha-cljs on a project generated from the fighwheel-main template fails, with cljs repl - document is not defined error.
"Execution error (ReferenceError) at (<cljs repl>:1).\ndocument is not defined\n"
The figwheel-main test runner succuessfully runs runs the 2 unit tests that are generated from the figwheel-main template, using the command clojure -M:fig:test. Both tests pass.
Reproduction guide :beetle:
an example project can be found at: practicalli-john/clojurescript-figwheel-main-hello-world
- Generate a new project using the fighwheel-main template with the
--reagentoption (:project/newis a user-level alias for clj-new)
clojure -M:project/new figwheel-main practicalli/hello-world -- --reagent
- Add koacha-cljs following the instructions in the README (commit on example repo)
- add an alias called :kaocha-cljs to deps.edn
:kaocha-cljs
{:extra-paths ["test"]
:extra-deps {com.lambdaisland/kaocha-cljs {:mvn/version "1.2.123"}}}
- create a
tests.ednfile
#kaocha/v1
{:source-paths ["src"]
:tests [{:id :unit-cljs
:type :kaocha.type/cljs
;; :test-paths ["test"]
;; :cljs/timeout 10000 ; 10 seconds, the default
;; :cljs/repl-env cljs.repl.node/repl-env ; node is the default
;; :cljs/repl-env cljs.repl.browser/repl-env
}]}
The same error occurs with our without the
:source-pathsvalue
- create a
bin/kaochafile
#!/usr/bin/env sh
[ -d "node_modules/ws" ] || npm install ws
clojure -M:kaocha-cljs -m kaocha.runner "$@"
- run tests using
bin/kaocha unit-cljs
Observed behaviour: :eyes: :broken_heart: The command line shows the test run has an error and prints out a long stack trace

Expected behaviour: :heart: :smile: kaocha-cljs should discover and run two unit tests and both tests should pass
System Info :computer:
document is not defined
This usually means you're using libraries that expect a DOM (i.e. they expect to find js/document), but you are using them in an environment where there is no DOM, typically Node. That's also what is happening here. You are including goog.dom and reagent.dom, so it's clear you expect to find a DOM, and kaocha-cljs's default behavior is to use the Node REPL to execute tests.
If I instead instruct it to use a browser REPL then all is well.

If there's anything actionable here it's probably to add a FAQ about this particular error to the README. A similar thing can happen with js/fetch
