backbone.js - Jasmine / Backbone -

my jasmine tests used pass. however, implemented base backbone view provides functionality few common views. after this, cannot simple test below pass. seems dom element (div) not exist, show view not rendering properly. thoughts or recommendations on why occurring , ways solve it?

two backbone views, 1 extends off of other:

var stockshowview = base.extend({   tagname: 'div',   classname: 'showsecurity',   template: _.template(showtpl),   ....   render: function() {     this.$el.html(this.template({       stock: this.model.tojson()     }));   }   ....return stockshowview;  var base = backbone.view.extend({   initialize: function() {....//no render function 

jasmine test

  stock_showview = new stockshowview({model: model});   stock_showview.render();    expect(stock_showview.tagname).toequal('div'); 

error

 cannot read property 'length' of undefined 

router

  router.on('route:showpost', function(id) {     if (globals.stocks) {       var stockpost = new stockmodel({_id: id});         stockpost.fetch({           reset: true,           success: function(stockpost) {             var stock_showview = new stockshowview({model: stockpost});             $("#view_box").html(stock_showview.render().el);           }       }); 

you should write tagname element uppercase letters. try this:

expect(stock_showview.el.nodename).toequal("div");
