Great episode! Instead of testing private methods directly, I suggest to define a FakeApiClient class that extends ApplicationClient with some dummy methods. This allows testing public methods. Plus, it allows you to remove the BASE_URI constant from ApplicationClient and define it in FakeApiClient.
Great, I like your screencasts about Stimulus a lot!

Why didn't you use that?
