Testing components from a user’s perspective ensures your application is accessible and behaves as users expect. With over 12 years of React development experience since 2014 and as the creator of CoreUI, I’ve adopted React Testing Library as the standard for component testing. React Testing Library (RTL) encourages testing components the way users interact with them, focusing on accessibility and user behavior. This approach creates tests that are more maintainable and closely aligned with real-world usage.
