testing the new constructor

[mwillhite]

This may just be a huge oversight due to my lack of experience, but I
can't seem to find a good way to test that an object was instantiated.

Say I have the following:

var blah = function() {
new google.maps.LatLng(123, 456);
}

How can I ensure that the google.maps.LatLng object was instantiated
(or constructed?) ?

Thanks!

I think you would just stub it out like any other function:

spyOn(google.maps, 'LatLng');

Note that in your spec file, google.maps must have the LatLng function defined as part of its structure, or else youll get an undefined function error.

You can even demonstrate that it was returned:

var blah = function() {
return new google.maps.LatLng(123, 456);
}

var latLng = {};
spyOn(google.maps, 'LatLng').andReturn(latLng);
expect(blah()).toBe(latLng);
