Question

我是ROR的新手，我正在关注Hartl的ruby on rails教程。当我通过时，第6章的测试失败了：

$ bundle exec rspec spec /

以下测试失败：

以下是用户模型：

class User < ActiveRecord::Base
    before_save { self.email = email.downcase }
validates :name,  presence: true, length: { maximum: 50 }
 VALID_EMAIL_REGEX = /\A[\w+\-.]+@[a-z\d\-.]+\.[a-z]+\z/i
  validates :email, presence: true, format: { with: VALID_EMAIL_REGEX },

uniqueness: { case_sensitive: false }
  has_secure_password
 validates :password, presence: true, length: { minimum: 6 }
  validates :password_confirmation, presence: true
end

这是RSpec模型/ user_spec.rb：

require 'spec_helper'

describe User do
 before do
     @user = User.new(name: "Example User", email: "user@example.com",
             password: "foobar", password_confirmation: "foobar") 
 end

  it { should respond_to(:name) }
  it { should respond_to(:email) }
  it { should respond_to(:password_digest) }
  it { should respond_to(:password) }
  it { should respond_to(:password_confirmation) }
  it { should respond_to(:authenticate) }

  it { should be_valid }

    let(:found_user) { User.find_by(email: @user.email) }

    describe "with valid password" do

Answer 1

您已定义以下路线

users_new  GET    /users/new(.:format)                 users#new
root       GET    /                                    static_pages#home
signup     GET    /signup(.:format)                    users#new
help       GET    /help(.:format)                      static_pages#help
about      GET    /about(.:format)                     static_pages#about

在static_pages_spec.rb中，您访问的路由为visit '/static_pages/home'，visit '/static_pages/help'和visit '/static_pages/about'，这显然会导致No route matches错误，因为这些路线不会不存在（将它们与上面列出的路线匹配）。

您需要在static_pages_spec.rb中进行以下更改：

错误：No route matches [GET] "/static_pages/home"

替换
```
visit '/static_pages/home'
```
用

visit root_path或visit '/'
错误：No route matches [GET] "/static_pages/help"

替换
```
visit '/static_pages/help'
```
用

visit help_path或visit '/help'
错误：No route matches [GET] "/static_pages/about"

替换
```
visit '/static_pages/about'
```
用

visit about_path或visit '/about'

您在user_pages_spec.rb文件中收到后两个错误：

错误：undefined method 'full_title'

它清楚地表明您使用的是一个名为full_title的方法，而这个方法没有在任何地方定义。
```
it { should have_title(full_title('Sign up')) } 
                       ## ^
                       ## full_title method here is undefined
```
错误：expected #has_content?("Sign up") to return true, got false

此错误仅表示以下示例失败
```
it { should have_content('Sign up') }
```
这意味着sign_up视图没有文字注册。确保sign_up视图的文字注册完全，匹配确切的案例。
