How to write a jquery unit test using jasmine?

I'm using angular version1 and need to test some jquery on my index.html page.

I have added jquery to my karma conf but when I run this test jquery is undefined.

Code I'm looking to test:

        <!-- Is Angular supported -->  
        <script>
            if(window.angular === undefined)              
                 $(function(){$("#angularNotSupportedModal").load("/app/noAngularModal.html");});
        </script>   

        <div id="angularNotSupportedModal"></div>      

My test code:

it('should call through $ chain', (done) => {
  var angular = window.angular;
  window.angular = undefined;

  spyOn(jQuery.prototype, 'ready').and.callThrough();
  spyOn(jQuery.prototype, 'load').and.callThrough();

  // make spy not break the chain
  var init = jQuery.prototype.init.bind(jQuery.prototype);
  spyOn(jQuery.prototype, 'init').and.callFake(init);

  window.runAngularNotSupportedFunction();

  expect(jQuery.prototype.ready).toHaveBeenCalledWith(jasmine.any(Function));
  expect(jQuery.prototype.init).toHaveBeenCalledWith('#angularNotSupportedModal', undefined);
  expect(jQuery.prototype.load).toHaveBeenCalledWith('/app/noAngularModal.html');

  window.angular = angular;
  jQuery.ready.promise().done(done)
})
