How to fake return calls from the geolocator in jasmine

[Nicola Peluchetti]

I have a function that calls the geolocator and i don't know how to test this function. I've tried spying on the geolocator and returning fake data but with no success, the original function is still used and so i would have to wait and i couldn't use mock data.

// this doesn't work        
var navigator_spy = spyOn( navigator.geolocation, 'getCurrentPosition' ).andReturn( {
    coords : {
        latitude : 63,
        longitude : 143
    }
} );

anyone knows how i can do this?

Can you post a more complete test example?

Hi dave, my need is simply to fake the calls to the geolocator. I have a working test that runs like this

if( !! navigator.geolocation ) {

it( "The map should be initialized with data from the geolocator if it is present and no coordinates are set", function() {

// Wait for the loading of the gmaps. This is simply when the <div> we use as a container has some html

waitsFor( function() {

return typeof gmaps_helper.get_position() !== 'undefined';

}, "gmaps never loaded", 15000 );

runs( function() {

expect( gmaps_helper.get_marker().position.lat() ).toBeCloseTo( gmaps_helper.get_position().coords.latitude, 5 );

expect( gmaps_helper.get_marker().position.lng() ).toBeCloseTo( gmaps_helper.get_position().coords.longitude, 5 );

} );

} );

} else {

it( "The map should be initialized with standard data if the geolocator is not present and no coordinates are set", function() {

// Wait for the loading of the gmaps. This is simply when the <div> we use as a container has some html

waitsFor( function() {

return $('#ai1ec_map_canvas').html() !== '';

}, "gmaps never loaded", 15000 );

runs( function() {

expect( gmaps_helper.get_marker().position.lat() ).toEqual( 9.965 );

expect( gmaps_helper.get_marker().position.lng() ).toEqual( -83.327 );

} );

} );

}

This works, but i have to wait for the geolocator to answer and that is slow. I can't run that test every time. And the geolocator function seems not to be spiable upon
