RSPEC 错误：预期 #<> 得到 #<>（使用 == 比较）- Ruby on Rails答案

【问题描述】：

我正在使用 RSPEC 在 ruby on rails 中测试我的控制器。这是我正在测试的控制器动作的（相关部分），

控制器代码：

 before do 
    @company=FactoryGirl.create(:company)
    @customer=FactoryGirl.create(:customer, company_id: @company.id)
    @job=FactoryGirl.create(:job, customer_id: @customer.id, company_id:  @company.id)
  end

class JobsController < ApplicationController
  def new
    if params[:customer_id]
      @job = current_member.company.jobs.new(
        customer_id: params[:customer_id],
        lead_id: params[:lead_id]
      )
     else
      ...
     end
    ...
  end

RSPEC 代码：

   it "has valid job with customer_id param" do 
      get :new, {:customer_id=>@customer.id, :lead_id=>@job.lead_id}
      expect(assigns(:job)).to eq @member.company.jobs.new(customer_id:@customer.id, lead_id:@job.lead_id)
    end

这是我得到的错误：

Failures:

   1) Failure/Error: expect(assigns(:job)).to eq @member.company.jobs.new(customer_id:@customer.id, lead_id:@job.lead_id)

   expected: #<Job id: nil, name: nil, status: "pending", company_id: 43, account_id_old: nil, job_type_id: nil, address_id: nil, trade_id: nil, lead_id: nil, started_date: nil, end_date: nil, created_at: nil, updated_at: nil, order_number: nil, creator_id: nil, account_id: nil, customer_id: 22, contact_id: nil>
        got: #<Job id: nil, name: nil, status: "pending", company_id: 43, account_id_old: nil, job_type_id: nil, address_id: nil, trade_id: nil, lead_id: nil, started_date: nil, end_date: nil, created_at: nil, updated_at: nil, order_number: nil, creator_id: nil, account_id: nil, customer_id: 22, contact_id: nil>

   (compared using ==)

我不明白，“预期”和“得到”部分似乎是同一件事！有什么想法/请帮忙？

【解决方案1】：

仅仅因为数据相同，并不意味着它们是相同的对象（它们不是）。

您确实需要单独检查有关分配对象的各种内容，例如：

before { get :new, { customer_id: @customer.id, lead_id: @job.lead_id } }

subject(:job) { assigns :job }

it { is_expected.to be_a_new Job }

it "should have the right customer_id" do
  expect(job.customer_id).to eq @customer.id
end

it "should have the right lead_id" do
  expect(job.lead_id).to eq @job.lead_id
end

...类似的东西。

【解决方案2】：

由于两个对象都没有保存，并且您不想测试它们是否完全相同，您可以检查它们的属性是否匹配，比较将在两个哈希之间进行

it "has valid job with customer_id param" do 
  get :new, {:customer_id=>@customer.id, :lead_id=>@job.lead_id}
  expect(assigns(:job).attributes).to eq @member.company.jobs.new(customer_id:@customer.id, lead_id:@job.lead_id).attributes
end
