使用Rspec重置密码测试

Question

我正在使用rails，并希望在Rspec中编写一个密码重置测试。我对测试很陌生。这就是我迄今为止所做的：

require 'rails_helper'
describe UsersController, type: :controller do
describe 'post #reset_password' do
let(:user) { create(:user) }
context "reset password" do  
  def do_request
    patch :update_password
  end
  before { do_request }
  it { expect(ActionMailer::Base.deliveries.count(1) } 
   end
  end
end

每次运行此程序时，都会在
中给ma一个语法错误CCD_ 1。我想检查电子邮件是否成功发送，以及用户是否在电子邮件中有密钥。谢谢

Answer 1

1）您最后在这里错过了)，因此出现了语法错误

it { expect(ActionMailer::Base.deliveries.count(1) } 

至

it { expect(ActionMailer::Base.deliveries.count(1)) } 

2）如果您想检查总交付量。你可以试试

  it 'should send an email' do
    ActionMailer::Base.deliveries.count.should == 1
  end

同时检查发送器

it 'renders the sender email' do  
    ActionMailer::Base.deliveries.first.from.should == ['[e-mail]']
end

同时检查主题行

it 'should set the subject to the correct subject' do
    ActionMailer::Base.deliveries.first.subject.should == 'Here Is Your Story!'
end

Answer 2

您遇到的问题很可能会通过编写更好的测试来解决。以下是您编写类似测试的一般方法。

让我们假设在你的路线文件中，你有一个后路线，看起来像这个

# config/routes.rb
post "/user/:id/reset_password", to: "users#reset_password"

你的用户控制器看起来像这个

# app/controllers/users_controller.rb
class UsersController
  ...
  def reset_password
    user = User.find(params[:id])
    user.reset_password!
    SomeMailClass.email_reset_instructions(user)
  end
end

你的User.rb模型看起来像这个

# app/models/user.rb
class User < ActiveRecord::Base
  def reset_password!
    update!(password: nil) # or whatever way you want/need to reset the password
  end
end

你有某种类型的邮件类来发送你的电子邮件

# app/models/some_mail_class.rb
class SomeMailClass
  def self.email_reset_instructions(user)
    # do something to send email...
  end
end

---

在控制器中进行测试的方法是

# spec/controllers/users_controller_spec.rb
require 'rails_helper'
describe UsersController, type: :controller do
  it "#reset_password" do
    user_id = double(:user_id)
    user = double(:user)
    expect(User).to receive(:find).with(user_id).and_return(user)
    expect(user).to receive(:reset_password!).and_return(true)
    expect(SomeMailClass).to receive(:email_reset_instructions).with(user)
    post :reset_password, id: user_id
  end
end

但你不应该就此打住。因为新制作的方法reset_password!和SomeMailClass的实现还有待测试。所以你应该为他们编写这样的模型/单元测试

# spec/models/user_spec.rb
require "rails_helper"
describe User do
  it ".reset_password!" do
    user = User.create(password: "foo")
    expect(user.password).to eq "foo"
    user.reset_password!
    expect(user.password).to eq nil
  end
end

然后您可以安装vcr和factory_girl gem，并像这样使用它们来测试您的邮件

# spec/models/some_mail_class_spec.rb
require "rails_helper"
describe SomeMailClass do
  VCR.use_cassette "email_reset_instructions" do |cassette|
    it ".email_reset_instructions" do
      user = FactoryGirl.create(:user)
      SomeMailClass.email_reset_instructions(user)
      # you can write some expectations on the cassette obj to test. 
      # or you can write whatever expectations you need/desire
    end
  end
end

最后，如果前端发生了什么事情，用户会点击它发出这个帖子请求，你也会为它编写一个功能测试。

希望这能有所帮助！
