茉莉私有方法的单元测试

问题描述

我是编码的测试案例使用茉莉角度的应用程序。但是，许多内部方法声明为私人服务。

I was coding test cases for an angular application using jasmine. But many internal methods are declared as private in the services.

例如：

App.service('productDisplay', function(){
    var myPrivate = function(){
        //do sth
    }
    this.doOfferCal = function(product, date){
        //call myPrivate
        //do sth too
        return offer;
    }
});

使用茉莉它可以直接为doOfferCalcode测试，但我想要写myPrivate单元测试了。

Using jasmine it straightforward to code test for "doOfferCal" but I want to write unit test for myPrivate too.

我该怎么办呢？

先谢谢了。

推荐答案

有没有你想测试你的私有方法具体的原因是什么？

Is there a specific reason you wish to test your private methods?

通过测试 doOfferCal（），你含蓄地测试一个 myPrivate（）正在做正确的事情。

By testing doOfferCal(), you're implicitly testing that myPrivate() is doing the right thing.

虽然这是RailsConf上，三弟梅斯对。

Though this is for RailsConf, Sandi Metz has a very good talk on what should be tested.
