摩卡咖啡和嵌套对象 [英] mocha and nested objects

问题描述

不好意思，如果这是一个愚蠢的问题，我是新来的嘲弄者.

Excuse if this is a silly question, I am new to mocking.

我可以使用摩卡(mocha)做类似的事情:

I am able to use mocha to do things like:

person.expects(:first_name).returns('David')

如何模拟嵌套对象?

说我有一个属于某个人的产品，我想获得该人的名字.

Say I have a Product that belongs to a Person and I want to get the first name of that person.

在我的应用中，我可能会这样:

In my app I might do it like this:

product.person.first_name

我如何通过模拟获得相同的结果?

How would I get the same result using a mock?

推荐答案

作为shingara答案的替代方法，您可以使用mocha的any_instance方法它将检测对任何类实例的调用".

as an alternative to shingara's answer, you could use mocha's any_instance method "which will detect calls to any instance of a class".

Person.any_instance.expects(:first_name).returns('david')
