ruby-on-rails - 方法错误 : undefined method `sign_in' for RSpec

Question

在 Michael Hartl 的 Ruby on Rails 教程的第 9 章中，我遇到了 RSpec 测试的问题，因为他们看不到文件 utilities.rb 中定义的我的 sign_in 方法。我被卡住了，我检查了一切，看起来是正确的。我看到类似的帖子，其中 include ApplicationHelper 行对某人有所帮助，但我已经有了它，而且我对同一文件中的方法“full_title”没有任何问题。

utilities.rb:

def full_title(page_title)
  base_title = "Ruby on Rails Tutorial Sample App"
  if page_title.empty?
    base_title
  else
    "#{base_title} | #{page_title}"
  end
end

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

和失败的文件 user_pages_spec.rb:

require 'rails_helper'
include ApplicationHelper
...
...
...
describe "edit" 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
...
end

Answer 1

如果您很难包含该方法，您可以尝试将其直接包含在您的规范中。

require 'rails_helper'
...
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 
....


private

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

如果可行，请继续为您的规范创建一个带有辅助方法的新模块，然后将其包含在您的 spec_helper/rails_helper 中
