test cases - 14/10/2017 10:44 EDT

I am trying to learn angular js and jasmine test case. so I took a sample jasmine test cases and used it in my code sample testcase fiddle but in my fiddle when I include its breaking. in my console I see errors but not sure why its happening Uncaught ReferenceError: System is not defined Uncaught TypeError: [login to view URL] is not a function RangeError: Maximum call stack size exceeded* can you tell me how to fix it providing my code below [login to view URL] and can you tell me how to write a simple test case for my tab function $('[login to view URL] li').click(function() { var tab_id = $(this).attr('data-tab'); $('[login to view URL] li').removeClass('current'); $('.tab-content').removeClass('current'); $(this).addClass('current'); $("#" + tab_id).addClass('current'); }) $('.left').click(function() { move('left'); }) $('.right').click(function() { move('right'); })
