Spying on console.error() with Jasmine

I'm actually new to JavaScript as well as Jasmine. So it might be something really obvious that fixes my problem but I can't see it.

I want to check if (an already existing) JavaScript application calls console.error() while loading. I don't really see a way how to realise this with Jasmine. I've included the JavaScript file as well as the spec file in the SpecRunner.html.
But I take it that I somehow need to instantiate the application in order to test if it throws any errors on the console, right?

Or should I include the SpecRunner.html code only for this purpose into the HTML code of the app?

You can spy on console.error like this:

beforeEach(function(){

  spyOn(console, 'error');

})



it('should print error to console', function(){

  yourApp.start();

  expect(console.error).toHaveBeenCalled();

})
