API Coverage

vitest-native's mock engine covers every stable React Native public export; the unstable and experimental internals listed under Not covered are intentionally skipped. Parity isn't a one-time claim: a CI-gated check-compat script resolves the exact installed RN package, diffs its runtime export list against the mock weekly, and opens a tracking issue on any gap. The native engine runs real React Native, so coverage there is simply all of RN.

Components (27)

View, Text, TextInput, Image, ScrollView, FlatList, SectionList, VirtualizedList, VirtualizedSectionList, Modal, Pressable, Touchable, TouchableOpacity, TouchableHighlight, TouchableWithoutFeedback, TouchableNativeFeedback, ActivityIndicator, Button, Switch, RefreshControl, StatusBar, SafeAreaView, KeyboardAvoidingView, ImageBackground, InputAccessoryView, DrawerLayoutAndroid, ProgressBarAndroid

Component instance methods are supported via refs: TextInput (focus, blur, clear, isFocused), ScrollView (scrollTo, scrollToEnd), FlatList (scrollToIndex, scrollToOffset, scrollToEnd, recordInteraction), SectionList (scrollToIndex, scrollToLocation, scrollToEnd, recordInteraction).

APIs (30)

Platform, StyleSheet, Dimensions, Animated, Alert, Linking, Keyboard, AppState, BackHandler, Vibration, PermissionsAndroid, Appearance, PixelRatio, LayoutAnimation, Share, AccessibilityInfo, InteractionManager, PanResponder, ToastAndroid, ActionSheetIOS, LogBox, Easing, I18nManager, DeviceEventEmitter, Clipboard, AppRegistry, Settings, DevSettings, Systrace, PushNotificationIOS

Animated

Full animation API including timing, spring, decay, sequence, parallel, stagger, loop, delay, event, and arithmetic operators (add, subtract, multiply, divide, modulo, diffClamp). Animated.View, Animated.Text, Animated.Image, Animated.ScrollView are real React components (not string literals) compatible with RNTL.

Hooks (3)

useColorScheme, useWindowDimensions, useAnimatedValue

Native internals (8)

NativeModules, TurboModuleRegistry, UIManager, NativeEventEmitter, NativeAppEventEmitter, NativeComponentRegistry, NativeDialogManagerAndroid, requireNativeComponent

Utilities (11)

processColor, findNodeHandle, PlatformColor, DynamicColorIOS, RootTagContext, ReactNativeVersion, UTFSequence, codegenNativeCommands, codegenNativeComponent, registerCallableModule, unstable_batchedUpdates

Not covered

The following unstable / experimental / private exports are intentionally not mocked. These are React Native internals not intended for use in application code:

Export	Reason
DevMenu	Private dev tooling, not used in production code
experimental_LayoutConformance	Experimental API, subject to change without notice
unstable_NativeText	Internal renderer primitive
unstable_NativeView	Internal renderer primitive
unstable_TextAncestorContext	Internal context for Text nesting detection
unstable_VirtualView	Private experimental component
VirtualViewMode	Private experimental enum
unstable_DEFAULT_INITIAL_NUM_TO_RENDER	Experimental virtualized-collection API (RN 0.86+)
unstable_VirtualArray	Experimental virtualized-collection API (RN 0.86+)
unstable_VirtualColumn	Experimental virtualized-collection API (RN 0.86+)
unstable_VirtualColumnGenerator	Experimental virtualized-collection API (RN 0.86+)
unstable_VirtualRow	Experimental virtualized-collection API (RN 0.86+)
unstable_createVirtualCollectionView	Experimental virtualized-collection API (RN 0.86+)
unstable_getScrollParent	Experimental virtualized-collection API (RN 0.86+)

If your code imports any of these, provide one with vi.mock in a setup file:

// vitest.setup.ts
vi.mock('react-native', async (importOriginal) => ({
  ...(await importOriginal<typeof import('react-native')>()),
  unstable_NativeText: MyCustomMock,
}))
