Jest Tests fails
See original GitHub issueHello I’m getting this error when running the test with Jest. When I run my application it works correctly but in the test it fails.
Test suite failed to run
Missing Realm constructor - please ensure RealmReact framework is included!
at Object.<anonymous> (node_modules/realm/lib/index.js:37:11)
at Object.<anonymous> (app/models.js:6:12)
at Object.<anonymous> (__tests__/models/location.test.js:2:13)
This is my configuration

app/models.js
import Realm from 'realm';
// More imported models
class Location {
get readableLocation() {
return `${this.city} - ${this.country} - ${this.latitude} - ${this.longitude}`;
}
}
Location.schema = {
name: 'Location',
properties: {
city: 'string',
country: 'string',
latitude: 'double',
longitude: 'double'
}
};
export default new Realm({
schema: [Location /* More schemas */]
});
Test
jest.unmock('../../app/models');
import realm from '../../app/models';
let context = describe;
describe('Location', () => {
context('.readableLocation', () => {
beforeEach(() => {
realm.write(() => {
realm.create('Location',
{
city: 'Medellín',
country: 'Colombia',
latitude: 123,
longitude: 1231
}
);
});
});
it('returns the full locations with city, country, latitude, longitude', () => {
let location = realm.objects('Location')[0];
let expected = `${location.city} - ${location.country} - ${location.latitude} - ${location.longitude}`;
expect(location.readableLocation).toBe(expected);
});
});
});
EDIT
I ran rnpm link realm
and added the new RealmReactPackage()
to the Main application

Hey folks,
We’ve been super busy with the recent launch of the Realm Mobile Platform and we haven’t had the time to investigate these Jest hangs. I’ll try to make time to look into the matter as soon as I can.
This is still causing issues for me. Just importing Realm and not using it at all is enough to prevent Jest from ever finishing.
