Spying on JQuery Selectors in Jasmine

Question

I am unit testing some JavaScript with Jasmine and wish to spy on (mock) an element of the DOM that is accessed by a jQuery selector.

My spec is:

it(         


        

Answer 1

Seems like I found good solution

    it "should open past statuses", ->
      # We can't use $('.past') here cause each time $('.past') called it returns different objects
      # so we need to store spy in variable
      showSpy = spyOn($.fn, 'show')
      # do the stuff
      $('.show-past').click()
      # then check if 'show' action was called
      expect($.fn.show).toHaveBeenCalled()
      # and if it realy our object
      expect(showSpy.mostRecentCall.object.selector).toEqual('.past')

This is not based on your code but i hope this can help someone. And, yes, example in CoffeScript.
