Google Chrome: Override geolocation via console

Question

So a little background for my question; I am writing a simple driving instructions web application using Google Maps directions API which provides me with a LatLng path along with text instructions.

In order to test this application (without driving around in a car) I need to simulate a geolocation-path. Google Chrome supports overriding geolocation data via the sensors developer settings, which works fine with one coordinate at the time.

So my question is - is it possible to set the browsers navigator.geolocation data via the console (i.e. javascript api) instead manually updating the value in the sensors settings menu?

I know that in this case I could just use another input source than the browser geolocation data and use a static array of LatLng's, or override the browsers navigator.geolocation.getCurrentPosition, but I figured that it would be more sophisticated to override the sensors instead.

Thanks in advance.

One way is to override the function navigator.geolocation.getCurrentPosition with your own custom function. Inside the custom function you can customize the value of latitude & longitude.

var customPosition = {};
customPosition.coords = {};
customPosition.coords.latitude = 41.89;
customPosition.coords.longitude = 2.89;

navigator.geolocation.getCurrentPosition = function(success, error){
    success(customPosition);

};

function success(position) {
    var latitude  = position.coords.latitude;
    var longitude = position.coords.longitude;

    console.log("latitude: " + latitude);
    console.log("longitude: " + longitude);
  }
