I'm trying to test my Google Maps component in vue and the navigator.geolocation.getCurrentPosition() is within the method



This test fails, printing out this in the console:



The error:
TypeError: Cannot read property 'getCurrentPosition' of undefined



  167 |     },
168 | geolocate: function() {
> 169 | navigator.geolocation.getCurrentPosition(position => {
| ^


This is my code



          export default {
name: "GoogleMap",
data() {

},

created() {

},

mounted() {
this.geolocate();
},

methods: {
..............
geolocate: function() {
navigator.geolocation.getCurrentPosition(position => {
this.center = {
lat: position.coords.latitude,
lng: position.coords.longitude
};
});
...............
},
computed: {

}
};

</script>


I have tried to mock it but I it has no effect



    describe("Maps.vue", () => {
it("renders ... Google maps ", () => {
const wrapper = shallowMount(Maps, {

mocks : {
getCurrentPosition:()=> jest.fn()

},
})
expect().....
})
})


How can I "mock" out this navigator method and get the test to pass?
