React Testing: Library

// Navigate to profile await userEvent.click(screen.getByRole('link', { name: /profile/i })) expect(screen.getByText(/user profile/i)).toBeInTheDocument()

// Wait for loading to complete expect(screen.getByText(/loading/i)).toBeInTheDocument() react testing library

// Verify dashboard expect(await screen.findByText(/welcome, user/i)).toBeInTheDocument() // Navigate to profile await userEvent

React Testing Library encourages writing accessible, user-focused tests that give you real confidence in your application. The key is always asking: "Is this how a user would interact with and observe this component?" { result.current.increment() })

// Simulate user interaction await userEvent.click(button)

act(() => { result.current.increment() })
