Question

我是一个在轨道上进行测试的菜鸟，并没有遵循TDD，因此我在事后进行了测试。我知道我的代码在我理智检查时有效，但我不能让这个简单的测试工作，我不知道为什么。我试图了解有关测试的更多信息，因此我可以成为更好的rails开发人员，并可以使用您的帮助。

我正在使用＆＃34; show＆＃34; ＆＃34;公司的行动＆＃34;控制器作为仪表板。我做的一件事是在仪表板上显示所有付款（显示在控制器代码中）。我只是试图测试当你获得show动作时@payments被正确分配了。

这是我不断收到的失败信息：

  1) CompaniesController GET show reacts to authenticated users sets @payments                                                                                                                                                                                              
 Failure/Error: expect(assigns(:payments)).to match_array([payment1, payment2])                                                                                                                                                                                         
   expected a collection that can be converted to an array with `#to_ary` or `#to_a`, but got nil                                                                                                                                                                       
 # ./spec/controllers/companies_controller_spec.rb:20:in `block (4 levels) in <top (required)>'

测试：（＆＃34;设置@ payments＆＃34;测试是唯一失败的）

require 'rails_helper'

describe CompaniesController do 

describe "GET show" do

    context "reacts to authenticated users" do
        log_in_user

        it "sets @company" do
            company = Fabricate(:company)
            get :show, id: company.id
            expect(assigns(:company)).to eq(company)
        end

        it "sets @payments" do
            company = Fabricate(:company) 
            payment1, payment2 = Fabricate(:payment, company: company), Fabricate(:payment, company: company)
            get :show, id: company.id
            expect(assigns(:payments)).to match_array([payment1, payment2])
        end
      end
    end
  end

控制器：

class CompaniesController < ApplicationController
  before_action :authenticate_user!, if: :user_signed_in?
  before_filter :correct_user, only: [:edit, :update, :show, :destroy]

  def show
    @user = current_user
    @company = @user.company
    @payments = @company.payments.order(id: :desc).page params[:page]
    @payments_count = @company.payments.all
    @refunds_count = @company.refunds.all
    @refunded_amount = @refunds_count.sum(:amount)
    @revenue = @company.payments.all.sum(:amount) - @refunded_amount
    @refund = Refund.new
  end
end

Answer 1

@payments来自您登录的用户的公司，因此您还需要确保log_in_user人员current_user与您想要获得的@payments公司

rspec指定（has_many关联）不起作用
