Ruby Mocha如何对嵌套哈希进行存根处理? [英] How does Ruby Mocha stub a nested hash?

问题描述

我这里有一个需要使用Mocha进行模拟的方法，但是目前我不知道如何在这里模拟嵌套的哈希.

I have a method here that needs to be mocked using Mocha, but currently i have no clue how to mock the nested hash here.

Products.new(:A => "aa", :B => "bb").containers['container_A'].elements['element_b']

到目前为止，我知道如何对Products.new(:A => "aa", :B => "bb")进行存根处理，但是对后面的哈希部分一无所知.

So far, i know how to stub Products.new(:A => "aa", :B => "bb"), but have no idea with the hash part after it.

谢谢.

推荐答案

hash/OpenStruct怎么样?

require 'ostruct'

product.expects(:containers).
        returns('container_A' => OpenStruct.new(:elements => {'element_b' => 'expected_value'}))

puts product.containers['container_A'].elements['element_b']
# => expected_value
