Answer 1

I'm using a kendo grid and therefore can't change the implementation to a getter method but I want to test around this (mocking the grid) and not test the grid itself. I was using a spy object but this doesn't support property mocking so I do this:

    this.$scope.ticketsGrid = { 
        showColumn: jasmine.createSpy('showColumn'),
        hideColumn: jasmine.createSpy('hideColumn'),
        select: jasmine.createSpy('select'),
        dataItem: jasmine.createSpy('dataItem'),
        _data: []
    } 

It's a bit long winded but it works a treat
