First of all, we are going to test a very simple Hook that does not make use of contexts or asynchronous code such as timeouts. To do this, we are going to create a new Hook called useCounter. Then, we are going to test various parts of the Hook.

The following tasks will be covered in this section:

• Creating the useCounter Hook
• Testing the result
• Testing Hook actions
• Testing the initial value
• Testing reset and forcing re-rendering

Let's get started now.
