当Backbone.Model更改时,我应该如何检查Backbone.View

我正在为一个使用backbone和backbone.marionette通过jasmine的web应用程序编写测试。

我的问题是:
1) 当模型发生变化时,我是否应该检查视图,看看视图是否受到影响?
2) 如果是,正确的方法是什么。例如在以下情况(1)中

我想避免更改模板文件

(1)

// template 

<ul class="widget-points-status">
    <li>
        <strong>{{ remaining_points }}</strong>
    </li>
    <li>
        <strong>{{ given_points }}</strong>
    </li>
    <li>
        <strong>{{ received_points }}</strong>
    </li>
</ul>

// My jasmine test could be:

describe('Changing the model:', function () {
    beforeEach(function () {
        app.currentUser.set({
            given_points: 111980,
            received_points: 892378,
            remaining_points: 435412
        });
    });

    it('it should change the points', function () {
        var pointsView = this.view.$el.text().match(/\d{1,}/)[0];
        expect(pointsView).toMatch(app.currentUser.get('given_points'));
        expect(pointsView).toMatch(app.currentUser.get('received_points'));
        expect(pointsView).toMatch(app.currentUser.get('remaining_points'));
    });

});

var pointsView = Backbone.View.extend({

    className: 'widget widget-profile',

    initialize: function () {
        app.currentUser.on('change', this.render, this);
    },

    render: function () {
        this.$el.html(profileTemplate(app.currentUser.toJSON()));

        return this;
    }
});
