javascript - Testing anchor links call with Mocha & Sinon -

i writing test case spy on google tracking calls on click event. there 2 scenarios covered in code. one, traverse hyperlinks on page , call click method inside loop. second, write independent test cases individual elements.

describe("container tags automated test suite", function() {      var spy;     var assert = sinon.assert;      beforeeach(function() {         spy = sinon.spy(window.spyconfig.object, window.spyconfig.method);     });      aftereach(function() {         spy.restore();     });      // trackable links & total links count     var links = $("a.wrapper-link"),         linkscount = links.length;      //first appraoch : make array of links     for(var i=0; < linkscount ; i++) {         ("track page links", function() {             link = $(links[i]);             link.click();             assert.called(spy);         });      }      //second approach : invidual selectors     ("track single link", function() {         link = $('a.wrapper-link');         link.click();         assert.called(spy);     });  }); 

problem: working fine if use independent jquery selectors each test case. eg. test case "track single link" got pass on every execution.

but, first approach make array on links , bind click event elements forcing test case fail. trying hard last couple of hours didn't luck find root cause of issue. please help.

this common error loops @ end i === linkscount when test running. have wrap call test function , passing i save in scope of function.

//first appraoch : make array of links  for(var i=0; < linkscount ; i++) {     (function(cnt){       ("track page " + cnt + ". link", function() {         link = $(links[cnt]);         link.click();         assert.called(spy);       });      })(i) }
