使用rspec / devise进行登录集成测试 [英] Login integration test with rspec/devise

问题描述

我正在使用Rspec和capybara，以及设计用户认证

这是我的代码：

requests / authentications_spec.rb

 描述'登录'do 
之前{访问root_path} 
主题{page} 
 
描述'应该能够登录'do 
 before $ 
 user = FactoryGirl.create（：user）
 fill_in：user_email，with：user.email 
 fill_in：user_password，with ：user.password 
 click_on'登录'
 end 
 it {should have_link'注销'} 
 end 
 end 
  

工厂/ user_factory.rb

  FactoryGirl .define do 
 factory：user do 
 sequence（：first_name）{| n | FirstName＃{n}} 
 sequence（：last_name）{| n | LastName＃{n}} 
 sequence（：email）{| n | foo#{n}@example.com} 
密码'foobar'
 password_confirmation'foobar'
 created_at Time.now 
 updated_at Time.now 
 end 
 end 
  

_login_form.html.erb，
此表单在应用程序中呈现布局标题。

 <％= form_for（资源，as：resource_name，url：session_path（resource_name），html：{id ：'login-mini-form'}）do | f | ％GT; 
<％= f.email_field：电子邮件，占位符：'您的电子邮件'％> 
<％= f.password_field：密码，占位符：'******'％> 
<％= f.submit登录，id：'login-button'％> 
 
<％ - 如果devise_mapping.rememberable？ - ％GT; 
<％= f.check_box：remember_me％> <％= f.label：remember_me％> 
<％ -  end  - ％> 
 
<％end％> 
  

在布局中我有这样的东西：

如果user_signed_in是

  
 render'devise / menu / logout_button'
 else 
 render'devise / menu / login_form'
 end 
  

测试正在给我

  1）用户应该能够记录在有效的凭据
失败/错误：它{应该有_link'注销'} 
期望链接注销返回一些
＃./spec/requests/authentications_spec.rb:117 ：在$（$）
 
 $ block $（$ 6）
 
完成0.71406秒
 8个例子，2个失败，2个待处理
  

我不知道为什么我的测试不通过。任何想法？

非常感谢！

编辑：我得到相同的行为测试注册： code> expect {click_button register_button}。to change（User，：count）.by 1 ，测试返回：

 失败/错误：期望{click_button register_button}。更改（用户，计数）。1 
计数应该已更改1，但更改为0 
  

解决方案

所以，我发现没有工作：

 描述'登录'do 
之前{visit root_path} 
 subject {page} 
 
描述'应该能够登录'do 
 before 
 user = FactoryGirl.create（：user）
 fill_in：user_email，with：user.email 
 fill_in：user_password， with：user.password 
 click_on'登录'
 end 
 it {should have_link'注销'} 
 end 
  

正确代码实际上是：

 描述'登录'do 
 before {visit root_path} 
 subject { 
 
描述'应该能够登录'do 
之前
 user = FactoryGirl.create（：user）
 fill_in'user_email'，其中： user.email 
 fill_in'user_password'，其中：user.password 
 click_on'登录'
 end 
 it {should have_link'注销'} 
 end 
 end 
 end 
  

似乎Capybara fill_in方法不采取符号ids只是字符串的参数。
傻我。

I'm having troubles making an integration test, for the user login in my rails application, pass.

I'm using Rspec and capybara, as well as devise for user authentication

Here is my code :

requests/authentications_spec.rb

describe 'log in' do
  before { visit root_path }
  subject { page }

  describe 'should be able to log in' do
    before do
      user = FactoryGirl.create(:user)
      fill_in :user_email, with: user.email
      fill_in :user_password, with: user.password
      click_on 'Log in'
    end
    it { should have_link 'Log out' }
  end
end

factories/user_factory.rb

FactoryGirl.define do
  factory :user do
    sequence( :first_name )  { |n| "FirstName#{n}" }
    sequence( :last_name )  { |n| "LastName#{n}" }
    sequence( :email ) { |n| "foo#{n}@example.com" }
    password              'foobar'
    password_confirmation 'foobar'
    created_at            Time.now
    updated_at            Time.now
  end
end

_login_form.html.erb, This form is rendered in the application layout header.

<%= form_for(resource, as: resource_name, url: session_path(resource_name), html: { id: 'login-mini-form' }) do |f| %>
  <%= f.email_field :email,       placeholder: 'Your email' %>
  <%= f.password_field :password, placeholder: '******' %>
  <%= f.submit "Log in", id: 'login-button' %>

  <%- if devise_mapping.rememberable? -%>
    <%= f.check_box :remember_me %> <%= f.label :remember_me %>
  <%- end -%>

<% end %>

In the layout I have something like that :

if user_signed_in?
  render 'devise/menu/logout_button'
else
  render 'devise/menu/login_form'
end

The test is giving me

1) User should be able to log in with valid credentials 
     Failure/Error: it { should have_link 'Log out' }
       expected link "Log out" to return something
     # ./spec/requests/authentications_spec.rb:117:in `block (6 levels) in <top (required)>'

Finished in 0.71406 seconds
8 examples, 2 failures, 2 pending

I don't get why my test is not passing. Any ideas ?

Thanks a lot !

Edit : I get the same behavior testing the registration with : expect { click_button register_button }.to change(User, :count).by 1, the test returns :

Failure/Error: expect { click_button register_button }.to change(User, :count).by 1
       count should have been changed by 1, but was changed by 0

解决方案

So, I have found what was not working :

describe 'log in' do
  before { visit root_path }
  subject { page }

  describe 'should be able to log in' do
    before do
      user = FactoryGirl.create(:user)
      fill_in :user_email, with: user.email
      fill_in :user_password, with: user.password
      click_on 'Log in'
    end
    it { should have_link 'Log out' }
  end

The correct code is in fact :

describe 'log in' do
  before { visit root_path }
    subject { page }

    describe 'should be able to log in' do
      before do
        user = FactoryGirl.create(:user)
        fill_in 'user_email', with: user.email
        fill_in 'user_password', with: user.password
        click_on 'Log in'
      end
      it { should have_link 'Log out' }
    end
  end
end

It seems Capybara fill_in method doesn't take a symbol as an argument for ids but only strings. Silly me.
