Jest Native is a companion library for React Native Testing Library that provides custom element matchers for Jest.

npm install --save-dev @testing-library/jest-native

;<View>
  <View testID="not-empty">
    <Text testID="empty" />
  </View>
  <Text testID="visible">Visible Example</Text>
</View>

expect(queryByTestId(baseElement, 'not-empty')).not.toBeEmpty()
expect(getByText(baseElement, 'Visible Example')).toBeVisible()

Note: when using some of these matchers, you may need to make sure you use a query function (like queryByTestId) rather than a get function (like getByTestId). Otherwise the get* function could throw an error before your assertion.

Check out Jest Native's documentation for a full list of available matchers.
