var editor;
return Backbone.Marionette.ItemView.extend({
      onShow:function(){
           editor=_.clone(ace);
            .................
      }
       enable:function(){
            edit.onPaste = editor.onPaste;
             ..............
      }
}

I am new to js Now i want to write a test case for the function enable. here editor is declared as global and is intialized in onshow function. i am getting editor as undefined in the test for enable function, how to resolve this. please help me Thank you.

The test case is like

it('Case #1:Check the enablerule Action function',function(){             
   expect(complexView.enableruleAction(view)).to.equal(undefined);
            });
