Testing with Jest

Mocking native modules

In order to load mocks provided by RNGH add following to your jest config in package.json:

"setupFiles": ["./node_modules/react-native-gesture-handler/jestSetup.js"]

Example:

"jest": {

"preset": "react-native",

"setupFiles": ["./node_modules/react-native-gesture-handler/jestSetup.js"]

}

Testing Gestures' and Gesture handlers' callbacks

RNGH provides an API for triggering selected handlers:

• fireGestureHandler(gestureOrHandler, eventList)
• getByGestureTestId(testID)
