React Native ondersteunt testen op meerdere niveaus — unit tests (logica), component tests (met React Native Testing Library), en end-to-end tests (met Detox). Een goed teststrategie verbetert betrouwbaarheid en vertrouwen.
Unit- en component testen (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.()).();
});
