I've created a complete simplified example that replicates the problem I'm getting.

function TestObj() {

    var self = this;

    self.getStuff = function(aString, callback) {

        // TODO

    }

}



describe(server communications, function() {

    it(it calls the server, function() {

        var obj = new TestObj();

        obj.getStuff = jasmine.createSpy();

        // swap the above line for this and it makes no difference

        // spyOn(obj, getStuff);



        var functionVar = function() {

        };



        obj.getStuff(hello, functionVar);



        expect(obj.getStuff).toHaveBeenCalledWith(

                [ hello, jasmine.any(Function) ]);

    });

});

Instead of a passing unit test, I get the following output:

Expected spy to have been called with:
[ [ 'hello',<jasmine.any(function Function() { [native code] })> ] ]
but was called with:
[ [ 'hello', Function ] ]

Why is it not recognising that the functions I pass in (function (){}) are actually functions? Whats that native code stuff it is expecting? Anyone else had this issue with jasmine.any(Function)? Thankyou!

EDITED

I tried using spyOn instead of jasmine.createSpy() and it makes no difference. I tried just a single argument and it works. Introducing the first string argument breaks the jasmine.any(Function) - any ideas?
