How to enable watch mode for recompiling cljs tests after files change?

[hirunatan]

Hello. I'm not sure i'm understanding how kaocha-cljs2 is supposed to work. I'm writing some ClojureScript library code, so it doesn't need a browser to run tests. I've managed to make a setup that builds a test bundle with shadow-cljs, with :target :node-test, adding the chui-runtime and setting autorun. So when I compile it, it opens a websocket with funnel, and start listening to run tests on demand from kaocha runtime. But I can't find a way of forcing the bundle to be recompiled when some source file changes.

Here is my configuration in shadow-cljs.edn:

{...
 :builds
   {:test
     {:target    :node-test
      :ns-regexp "^mylib-tests.*-test$"
      :output-to "target/tests.cjs"
      :output-dir "target/tests/"
      :test-dir "target/tests" del wp y el tríptico? del wp y el tríptico? del wp y el tríptico?
      :autorun true
      :runner-ns kaocha.cljs2.shadow-runner
      :main kaocha.cljs2.shadow-runner/start
      :preloads [lambdaisland.chui.remote]}}}

I run the build with

clojure -M:dev:shadow-cljs-kaocha compile test

with this alias in deps.edn:

{...
  :aliases
    {:dev
      {...
       :shadow-cljs-kaocha
       {:main-opts ["-m" "shadow.cljs.devtools.cli"]
        :extra-deps {lambdaisland/kaocha-cljs2 {:mvn/version "0.2.72"}
                     lambdaisland/chui {:mvn/version "1.2.205"}}}}}

And then I start kaocha this way:

clojure -M:dev:test --watch

Also with an alias:

{...
  :aliases
    {:dev
      {...
       :test
       {:main-opts ["-m" "kaocha.runner"]
        :extra-deps {lambdaisland/kaocha {:mvn/version "1.91.1392"}
                     lambdaisland/kaocha-cljs2 {:mvn/version "0.2.72"}}}

When shadow-cljs is run, it correctly compiles the build, load tests and opens a web socket:

$ clojure -M:dev:shadow-cljs-kaocha compile test
[:test] Compiling ...
========= Running Tests =======================
[lambdaisland.funnel-client] {:connecting "ws://localhost:44220", :line 54}
[goog.net.WebSocket] "Opening the WebSocket on ws://localhost:44220"
[kaocha.cljs2.shadow-runner] {:lambdaisland.chui/capture-test-data! {frontend-tests.util-simple-math-test {:name frontend-tests.util-simple-math-test, :meta {:
file "frontend_tests/util_simple_math_test.cljs", :line 7, :column 5, :end-line 7, :end-column 41},
...

And then I can launch kaocha runner and execute tests. And if I add --watch mode, it runs the tests again if sources change, but because shadow-cljs does not trigger, the build does not change and the executed tests are the same of the previous run, I can't see the changes.

Is there any way to tell chui to watch the source files? Or to relaunch shadow-cljs on changes?

Or is there a different, better way to do all of this? Thanks.
