Konacha Javascript规范中的存根单选按钮

Question

这是我的Javascript：

if $("#payment_cc:checked").length > 0
  path = "/orders"
  if @get('tokenize')
    @_submitWithToken(obj, path)
  else
    @_submitWithCC(obj, path)
else
  path = "/orders/paypal"
  @_submitWithCC(obj, path)

我正在尝试在我的Javascript规范中模拟，这样我就可以测试什么时候：

$("#payment_cc:checked").length == 1
$("#payment_cc:checked").length == 0

如何在Konacha测试中设置$("#payment_cc:checked")的length？

不需要设置jQuery元素选择的length，只需将单选按钮设置为手动选中，如下所示：

describe('when the radio is selected', function() {
    beforeEach(function() {
        $('#payment_cc').attr('checked', true);
    });

    it('should do something', function() {
        // Assert that the submission went the way you wanted it to
    });
});
