Selecting data to view
Let's add in some dynamic behavior to our page. We'll make each of the list items a link that the user can click on to view that appointment.
Thinking through our design a little, there are a few pieces we'll need:
- A button element within our li
- An onClick handler that is attached to that button element
- A component state to record which appointment is currently being viewed
When we test React actions, we do it by observing the consequences of those actions. In this case, we can click on a button and then check that its corresponding appointment is now rendered on screen.
