How to create unit test for a function in my case

I have something in my code like this.

$scope.callMe = function(test){
   ...
   myService.test(
       {'price':price, 'name':name, 'category': category, 'test': test}
   ) // category, price are complex objec
   ...
}

my unit test

it('should check the params', function(){
    spyOn(myService.test).and.callThrough();
    $scope.callMe('test1');

    expect(myService).toHaveBeenCalled();
}

I want to create a unit test to see if myService is called with a variable 'test1'. I don't want to use toHaveBeenCalledWith() because I have to mimic bunch of complex objects and I don't want to do that. The above test won't do it. Is there a way to solve it? Thanks a lot!
