Ionic unit testing geolocation fails

Question

Trying to unit test my new ionic2 application fails after adding the geolocation test cases. Here is a minimum example: https://github.com/geoHeil/ioni2GeolocationUnitTest

The error can be reproduced by running npm test

TypeScript error: app/services/geo/geolocation.service.spec.ts(30,38): Error TS2339: Property 'Coordinates' does not exist on type 'typeof ".../node_modules/ionic-native/dist/plugins/geolocation"'.

strangely even though I specified:

import  * as NativeGeo  from 'ionic-native/dist/plugins/geolocation';

this type definition seems to be used

edit

I just found Geolocation unit test with JsTestDriver which might be slightly related

Answer 1

I fixed it creating my own implementation of coordinates, like:

class MyCoordinates implements Coordinates {
    latitude: number;
    longitude: number;
    accuracy: number;
    altitude: number;
    altitudeAccuracy: number;
    heading: number;
    speed: number;
}
