RTL provides different ways to find elements. You should prioritize them in this order to ensure your tests are robust and accessible: afterEach(() => { cleanup() }) const customRender =

// Simulate user interaction await userEvent.click(button) ...options }) =&gt

// fireEvent - lower level, more immediate fireEvent.click(button) fireEvent.change(input, { target: { value: 'new' } })

npm install --save-dev @testing-library/react @testing-library/jest-dom
