Testing the reducer?

Development
1

In response to another post, @laurent describes the design as:

button dispatches an action. That action is then received by the reducer, which uses this to change the application state. The application state is then read by React to update its components. It’s basically a one way flow: Action -> Reducer -> View (React)

Are there any examples of test cases where the change to application state is checked in response to a test action?

Hmm do you have an example of what you mean? The app state is always (or should always be) the result of one or more actions.

Yes, I was specifically looking for where the handlers in the lib/reducer.js are tested. I suspect there are no tests for it yet, but I just wanted to confirm.

Indeed there are not tests for this at the moment. We lack tests for the front end in general.
