我目前正在研究Michael Hartl的Ruby on Rails教程。我在本章中遇到了4个不同的错误，非常感谢您帮助解决它们。

配置/ routes.rb中

Rails.application.routes.draw do

  root             'static_pages#home'
  get 'help'    => 'static_pages#help'
  get 'about'   => 'static_pages#about'

  get 'login'   => 'sessions#new'
  get 'login'   => 'sessions#create'
  get 'logout'  => 'sessions#destroy'
  resources :users
end

测试/集成/ users_login_test.rb

require 'test_helper'

class UsersLoginTest < ActionDispatch::IntegrationTest

  def setup
    @user = users(:michael)
  end

  test "login with valid information followed by logout" do
    get login_path
    post login_path, session: { email: @user.email, password: 'password' }
    assert is_logged_in?
    assert_redirected_to @user

    assert_select "a[href=?]", logout_path,      count: 0

  end

  test "login with remembering" do

  end

  test "login without remembering" do
    log_in_as(@user, remember_me: '0')
    assert_nil cookies['remember_token']

end

测试/ test_helper.rb中

ENV['RAILS_ENV'] ||= 'test'
require File.expand_path('../../config/environment', __FILE__)
require 'rails/test_help'

class ActiveSupport::TestCase
  fixtures :all

  # Returns true if a test user is logged in.
  def is_logged_in?
    !session[:user_id].nil?
  end

  # Logs in a test user.
  def log_in_as(user, options = {})
    password    = options[:password]    || 'password'
    remember_me = options[:remember_me] || '1'
    if integration_test?

                                  password:    password,
                                  remember_me: remember_me }
    else
      session[:user_id] = user.id

  end

  private

    # Returns true inside an integration test.
    def integration_test?
      defined?(post_via_redirect)
    end
end

测试/集成/ site_layout_test.rb

require 'test_helper'

class SiteLayoutTest < ActionDispatch::IntegrationTest

  test "layout links" do
    get root_path
    assert_template 'static_pages/home'
    assert_select "a[href=?]", root_path, count: 2
    assert_select "a[href=?]", help_path
    assert_select "a[href=?]", about_path
    assert_select "a[href=?]", contact_path
    get signup_path
    assert_select "title", full_title("Sign up")
  end
end

我弄得一团糟......非常感谢任何和所有帮助！

编辑：另外，我对这一切都很新，所以如果我在测试GREEN时应该删除旧测试，请告诉我。我不确定这些失败的测试是否会变成RED，因为我做错了什么，或者我应该在阅读教程时删除它们。谢谢！

Answer 1

在routes.rb

中

get 'login'   => 'sessions#new'
get 'login'   => 'sessions#create'

看起来很奇怪。我想应该是

get 'login'   => 'sessions#new'
post 'login'  => 'sessions#create'
