React Native podporuje testování na více úrovních — unit testy (logika), component testy (s React Native Testing Library) a end-to-end testy (s Detox). Dobrá testovací strategie zlepšuje spolehlivost a jistotu.
Unit a component testování (Jest + Testing Library)
JEST → the standard JS test runner (unit tests for logic, functions, hooks)
REACT NATIVE TESTING LIBRARY → test components by rendering and interacting with them
(the way a user would) — query elements, fire events, assert on output
{ render, fireEvent, screen } ;
(, {
();
fireEvent.(screen.());
(screen.()).();
});
