Jasmine: testing toHaveBeenCalledWith (params), where params is an object

I am testing Jasmine, having a weird result when looking for expected parameters as a result of a spy.

I am testing the toHaveBeenCalledWith () method and looking for something like this:

{
  foo: bar,
  thing: [1,2,3],
  etc: function() { blah; }
}

It fails, but the error message seems to confirm that the same object is indeed found.

Any reasons why this could be so?

The definitions of equivalent functions are not equal. In this way,

function() { return 'blah'; } == function() { return 'blah'; } // returns false

toHaveBeenCalledWith() Jasmine, , spied object. , (, , ), toHaveBeenCalledWith()? .

Jasmine, , , . :

describe("A spy example", function() {
    var baz  = {
        foo: 'bar',
        thing: [1,2,3],
        etc: function() { }
    };

    beforeEach(function() {
        spyOn(baz, 'etc');
        baz.etc(baz);
    });

    it("succeeds", function() {
        expect(baz.etc).toHaveBeenCalledWith(baz);
    });

    it("fails", function() {
        expect(baz.etc).toHaveBeenCalledWith({
            foo: 'bar',
            thing: [1,2,3],
            etc: function() { }
        });
    });
});
