React Testing Library provides a function called fireEvent() to fire an event.
For example:
fireEvent.change(input, { target: { value: 'hello world' } });However, you should prefer methods provided by the package
@testing-library/user-event over fireEvent(). While userEvent is built on
top of fireEvent(), it provides methods that simulate user interactions more
closely. For example userEvent.type() in the example below will trigger
keyDown, keyPress, and keyUp events for each character which is much
closer to the user's actual interactions.
userEvent.type(input, 'hello world');
