It's unlikely we will add support for matching across multiple calls. @jamesarosen What was the formatting issue? The toHaveBeenCalledWith() matcher returns true and the spec passes Sign in
The toHaveBeenCalledWith() matcher verifies whether the spied method has been called with the right argument(s). It's pretty much clear when jasmine will start collecting args in the order how they were invoked. Whoops - the problem was a formatting issue. The toHaveBeenCalledWith matcher supports arguments from a single call only because there's no clear way to distinguish between calls in the matcher arguments. I know I can check the args directly with argsForCall but I think toHaveBeenCalledWith reads better and is more appropriate. In order to create a mock with multiple … expect($.fn.get).toHaveBeenCalledWith([ [0],[0] ]); This is the case, where … I was fustrated that this wasn't working and I found out that you can use the obj.method.calls.allArgs() for this to work. they're used to gather information about the pages you visit and how many clicks you need to accomplish a task.

In this tutorial, we illustrate the workings of the toHaveBeenCalled(), toHaveBeenCalledWith() and toHaveBeenCalledTimes() spy matchers. to your account, expect($.fn.get).toHaveBeenCalledWith(0,0); For more information, see our Privacy Statement.
