Functionality Requirements

The component must have the following functionalities:

• The input should initially be empty.

• If no value is entered, clicking on the Add Customer button should not do anything.

• If a value is present, clicking on the Add Customer button should add the input value to the list below. For this, add <li>{input}</li> to the <ul data-test-id="customer-list"> element.

• After adding the value to the list, clear the value of the input box.

• Please note that the customer list <ul> element should only be rendered if it has at least one customer added (i.e., at least one <li> child). So initially, when the app is mounted, the <ul> element should not be rendered since no customers have been added.

• All the values added by the button should be rendered in the list below.

Testing Requirements

• The input should have the data-test-id attribute app-input.
• The button should have the data-test-id attribute submit-button.
• The customer list <ul> should have the data-test-id attribute customer-list.
• Elements in the list should have the data-test-id attribute as list-item0, list-item1, list-item2, list-item3, and so on.
