 Once that is done, we need to update the tests to match how RTK works.
 
-The first issue is that the test file hardcodes action types like `'ADD_TODO"`. RTK's action types look like `'todos/addTodo'`. We can reference that by also importing the action creators from the todos slice, and replacing the original type constants in the test with `addTodo.type`.

 The other problem is that the action objects in the tests look like `{type, id, text}`, whereas RTK always puts those extra values inside `action.payload`. So, we need to modify the test actions to match that.

 If we reload the app, we should still see that `state.todos` is an empty array. But, if we click on "Add Todo", nothing will happen. We're still dispatching actions whose type is `'ADD_TODO'`, while our todos slice is looking for an action type of `'todos/addTodo'`. We need to import the correct action creator and use it in the `AddTodo.js` file.
 
-While we're at it, there's a couple other problems with how the `AddTodo` component is written. First, it's currently using a React "callback ref" to read the current text value from the input when you click "Add Todo". This works, but the standard "React way" to handle form fields is with the "controlled inputs" pattern, where the current field value is stored in the component's state.

 Second, the connected component is getting `dispatch` as a prop. Again, this works, but the normal way to use connect is to [pass action creator functions to `connect`](https://react-redux.js.org/using-react-redux/connect-mapdispatch), and then dispatch the actions by calling the functions that were passed in as props.
