Hi all. I have a method which creates an HTML element and calls the appendChild method. I've now written a unit test for this method, and want to use the Sinon package to mock the call to appendChlid and count how many times it was called. But when I do that, Sinon reports it was called zero times, instead of one. How do I use Sinon to properly mock (spy) appendChild in this case? My code is below.
