// This mock is specially important because some libs still didn't updated
// the way to call NativeEventEmitter after a refactoring in react-native.
// Therefore, without it, test may complain with the following message:
// > Invariant Violation: new NativeEventEmitter() requires a non-null argument.
//
// See the react-native PR that introduce this problem:
// https://github.com/facebook/react-native/commit/114be1d2170bae2d29da749c07b45acf931e51e2
//
// The package that calls in ole fashion the NativeEventEmitter
// is the react-native-device-info.
//
// See the issue describing the problem and the solution:
// https://github.com/react-native-device-info/react-native-device-info/issues/1507

// jest-babel transformer ignores the node_module. Threfore,
// we should either mock the module or configure to add it
// in the transformation.
// See the issue discussion: https://github.com/oblador/react-native-keychain/issues/72#issuecomment-309809798
//
// A more elegant solution would be the react-native-keychain team
// provide a jest setup file. We may contribute with them creating one.
jest.mock('react-native-keychain');

// react-native-gesture-handler faces the same problem of
// react-native-keychain. However, the team provides a setupFile
// which we can use in the "setupFiles" configuration withing
// jest in package.json.
//
// Don't remove this comment, because this is a documentation
// to increase awareness about these corner cases.
//
// See the jestSetup.js file from the project:
// https://github.com/software-mansion/react-native-gesture-handler/blob/main/jestSetup.js
//
// This solution was elaboreated by many contributors in this issue:
// https://github.com/software-mansion/react-native-gesture-handler/issues/344
