Testing Library Meets React Native
summary
A thin layer on top of react-test-renderer becomes a concrete React Native testing library that supports deep rendering, Jest, msw mocks, fireEvent and accessibility queries; it fixes a bug where getByTestId returned non-native instances, auto-wraps async findBy queries in act, and removed shallow rendering to discourage implementation testing. Two nearly identical libraries appear, thousands of users adopt one within six months, and after API alignment and a v2 migration strategy the projects consolidate into @testing-library/react-native and continue maintained.
