user-event
Simulate user events
...For example userEvent.click(checkbox) would change the state of the checkbox. user-event is a companion library for Testing Library that simulates user interactions by dispatching the events that would happen if the interaction took place in a browser. fireEvent dispatches DOM events, whereas user-event simulates full interactions, which may fire multiple events and do additional checks along the way. Testing Library's built-in fireEvent is a lightweight wrapper around the browser's low-level dispatchEvent API, which allows developers to trigger any event on any element. The problem is that the browser usually does more than just trigger one event for one interaction. -
