`rspec` - 比较两个数组的长度 [英] `rspec` - comparing two arrays' lengths against each other

问题描述

在 index 方法中有 2 个数组，我想测试数组长度的相等性但它不起作用(手动测试后数组的长度相等)

Having 2 arrays in index method, I want to test the equality of the arrays' lengths but it's not working (the lengths of the arrays are equal after testing manually)

def index
    @countries = get_countries()
    @capitals = get_capitals()
end

Rspec 文件:

describe CountriesController do 
  describe 'index' do
    it 'countries.length == capitals.length' do
      expect(assigns(countries.length)).to eq (assigns(capitals.length))
    end
  end
end

推荐答案

您似乎不是在向该操作发出请求……也就是说……get :index 在哪里打电话?

Doesn't look like you are making a request to that action... that is.. where is the get :index call?
