[英]Ruby on Rails Tutorial by Michael Hartl. Failing Test in Chapter 9.1
[英]Hartl's Ruby on Rails Tutorial test failing (chapter 9)
我正在研究Hartl着名的Ruby on Rails 4教程。 我对Rails并不陌生,但是对测试却不陌生:RSpec,Capybara,FactoryGirl等。我在编辑第9章( http://ruby.railstutorial.com)中的用户时遇到了一些测试方面的问题。 org / chapters / updating-showing-and-deleting-users#sec-successful_edits )。 我将首先发布我试图纠正的内容,然后发布相关代码:
错误如下:
1) Authentication Signin page with valid information followed by signout

最初,我认为这是水豚问题,但是我不确定。 这是测试代码(位于./spec/requests/user_pages_spec.rb中):
describe "edit", :js => true do
let(:user) { FactoryGirl.create(:user) }
before do
sign_in user
visit edit_user_path(user)
end
describe "page" do
it { should have_content("Update your profile") }
it { should have_title("Edit user") }
it { should have_link('change', href: 'http://gravatar.com/emails') }
end
describe "with invalid information" do
before { click_button "Save changes" }
it { should have_content('error') }
end
describe "with valid information" do
let(:new_name) { "New Name" }
let(:new_email) { "new@example.com" }
before do
fill_in "Name", with: new_name
fill_in "Email", with: new_email
fill_in "Password", with: user.password
fill_in "Confirm Password", with: user.password
click_button "Save changes"
end
it { should have_title(new_name) }
it { should have_selector('div.alert.alert-success') }
it { should have_link('Sign Out', href: signout_path) }
specify { expect(user.reload.name).to eq new_name }
specify { expect(user.reload.email).to eq new_email }
end
end
我添加到初始描述块:js => true
因为我认为这是Capybara的问题,并且页面加载速度过快,但是,添加该哈希值会导致FF浏览器打开,我可以观察到发生了什么... FactoryGirl已成功创建用户,但是尝试登录时收到无效的电子邮件或密码错误。因此,登录失败,因此所有测试都无法通过编辑表单。 这是相关的FactoryGirl代码:
./spec/utilities.rb中的sign_in()帮助器:
def sign_in(user, options={})
if options[:no_capybara]
# Sign in when not using Capybara.
remember_token = User.new_remember_token
cookies[:remember_token] = remember_token
user.update_attribute(:remember_token, User.encrypt(remember_token))
else
visit signin_path
fill_in "Email", with: user.email
fill_in "Password", with: user.password
click_button "Sign In"
end
end
./spec/factories.rb:
FactoryGirl.define do
factory :user do
sequence(:name) { |n| "Person #{n}" }
sequence(:email) { |n| "person_#{n}@example.com"}
password "foobar"
password_confirmation "foobar"
factory :admin do
admin true
end
end
end
我已经正确安装了gem,FactoryGirl在其他测试中似乎可以正常工作,这是gemfile:
group :test do
gem 'selenium-webdriver', '2.35.1'
gem 'capybara', '2.1.0'
gem 'growl', '1.0.3'
gem 'factory_girl_rails', '4.2.1'
end
就像我说的那样,我查看了SQLite开发和测试数据库,但在测试数据库中没有看到任何用户。 FactoryGirl是否仅临时创建测试用户,然后在完成后回滚? 是什么导致我看到的失败标志? 还是我还缺少其他东西?
如果有人问,这里是相关的观点:
edit.html.erb:
<% provide(:title, "Edit user") %>
<h1>Update your profile</h1>
<div class="row">
<div class="span6 offset3">
<%= form_for(@user) do |f| %>
<%= render 'shared/error_messages' %>
<%= f.label :name %>
<%= f.text_field :name %>
<%= f.label :email %>
<%= f.email_field :email %>
<%= f.label :password %>
<%= f.password_field :password %>
<%= f.label :password_confirmation, "Confirm Password" %>
<%= f.password_field :password_confirmation %>
<%= f.submit "Save changes", class: "btn btn-large btn-primary" %>
<% end %>
<%= gravatar_for @user %>
<a href="http://gravatar.com/emails">change</a>
</div>
以及在application.html.erb中呈现的_header.html.erb
<header class="navbar navbar-fixed-top navbar-inverse">
<div class="navbar-inner">
<div class="container">
<%= link_to "sample app", root_path, id: "logo" %>
<nav>
<ul class="nav pull-right">
<li><%= link_to "Home", root_path %></li>
<li><%= link_to "Help", help_path %></li>
<% if signed_in? %>
<li><%= link_to "Users", users_path %></li>
<li id="fat-menu" class="dropdown">
<a href="#" class="dropdown-toggle" data-toggle="dropdown">
Account <b class="caret"></b>
</a>
<ul class="dropdown-menu">
<li><%= link_to "Profile", current_user %></li>
<li><%= link_to "Settings", edit_user_path(current_user) %></li>
<li class="divider"></li>
<li>
<%= link_to "Sign Out", signout_path, method: "delete" %>
</li>
</ul>
</li>
<% else %>
<li><%= link_to "Sign In", signin_path %></li>
<% end %>
</ul>
</nav>
</div>
</div>
</header>
您遇到的第一个错误很可能是因为您需要将describe "followed by signout"
嵌套在describe "after saving the user"
如下所示:
describe "after saving the user" do
before { click_button submit }
let(:user) { User.find_by(email: 'user@example.com') }
it { should have_link('Sign out') }
it { should have_title(user.name) }
it { should have_selector('div.alert.alert-success', text: 'Welcome') }
describe "followed by signout" do #Notice that this describe is inside the other one
before { click_link "Sign out" }
it { should have_link('Sign in') }
end
end
我知道这只是部分答案,但是很难一次解决所有问题。 解决此问题后,请再次运行测试,并告诉我留下了哪些错误代码。 我会尽力帮助您。
(至少如果这解决了您的第一个问题,则可能是其他问题)
