Description:

Jest test failing on TypeError: _reactNativeOnesignal.default.init is not a function

I am using jest tests and I've implemented oneSignal in my App.js
and when I try to run yarn test it then not passing tests.
Here is Error

My App.js file:

My App.test.js:

My jest-setup.js:

Hello,
Thank you for your patience. Were you able to resolve? I'd be interested in what notificationsService does. It would be helpful if you shared a sample project so I could build it and take a closer look.

[AfanasievN]

@rgomezp this is my NotificationService

And this one is NotificationsHandlers

Hello,
Could you please share a repro project with us through our support channel at onesignal.com so we can build it?

@AfanasievN OneSignal’s react native SDK is just a wrapper on top of a native SDK framework. Are your tests pure JS or do they emulate iOS/Android and load our native framework?

I would suggest using mocking so that your tests don’t use OneSignal react native code at all.

[AfanasievN]

Hello, @Nightsd01 @rgomezp I found a solution today.
I still don't know why but jest could not figure out functions after dot like on screen shot

My workaround is to add to my jest-setup file this code --->
jest.mock('react-native-onesignal', () => { return { OneSignal: jest.fn(() => 'undefined'), init: jest.fn(() => 'undefined'), inFocusDisplaying: jest.fn(() => 'undefined'), addEventListener: jest.fn(() => 'undefined'), }; });

Thanks for your time and awareness, we can close this issue

This error has fix?

I put the mock but this error continue

Test suite failed to run

Invariant Violation: Native module cannot be null.
import OneSignal from 'react-native-onesignal'
`jest.mock('react-native-onesignal', () => { ....`

Here is a full set of mock functions based on the OneSignal type definition. Because it is so large, I put it in a separate mock file, rather than use jest.mock in the jest setup file.
