Mini-Challenge 4: State Management

The Challenge

1. Create the Provider for the Global Context.
2. Consume the Global Context inside the components that require it: Remember the hook useContext? It's time to make use of it!
3. Create test cases for your Global Context and for the components that consume it.

Note: Remember to apply TDD as much as you can.

• The appearance theme is stored on the Global Context and applied correctly to the App UI.
• useReducer hook is implemented correctly to manage the Global State.

Bonus Points
