Question

我在Rails教程中第9章 - 更具体地说，在第9.1节末尾。我的问题类似于this thread中的问题，但那里的解决方案对我不起作用。

这是我的user_pages_spec.rb：

require 'spec_helper'
describe "User pages" do
subject { page }

describe "signup page" do
before { visit signup_path }

it { should have_content('Sign up') }
it { should have_title(full_title('Sign up')) }
end

describe "profile page" do
let (:user) {FactoryGirl.create(:user)}
before { visit user_path(user) }

it { should have_content(user.name) }
it { should have_title(user.name) }
end

describe "signup" do

before { visit signup_path }

let(:submit) { "Create my account" }

describe "with invalid information" do
  it "should not create a user" do
    expect { click_button submit }.not_to change(User, :count)
  end
end

describe "with valid information" do
  before do
    fill_in "Name",         with: "Example User"
    fill_in "Email",        with: "user@example.com"
    fill_in "Password",     with: "foobar"
    fill_in "Confirmation", with: "foobar"
  end

  it "should create a user" do
    expect { click_button submit }.to change(User, :count).by(1)
  end
end
end

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

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
end

以下是错误消息：

bundle exec rspec spec/
.............................................FFFFFFFFF

Failures:

 1) User pages edit page 
 Failure/Error: sign_in user
 NoMethodError:
   undefined method `sign_in' for #<RSpec::Core::ExampleGroup::Nested_4::Nested_4::Nested_1:0x007faa37859d80>
 # ./spec/requests/user_pages_spec.rb:49:in `block (3 levels) in <top (required)>'

这是我的spec / support / 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]
user.update_attribute(:remember_token, User.digest(remember_token))
else
visit signin_path
fill_in "Email", with: user.email
fill_in "Password", with: user.password
click_button "Sign in"
end
end

有什么建议吗？

我在尝试安装rcov时确实运行了bundle install（Rubymine抱怨它缺乏）。安装失败，因为rcov不适用于我的rails版本。没关系。

真奇怪的是，事后我重新进行了测试，一切正常。没有错误消息的痕迹。我是一个rails noob，但这有点丰富 - 一个失败的捆绑安装不会改变任何东西。没有理由我发现错误信息，现在它没有任何理由消失了。

==编辑：我意识到问题是rails似乎没有清空测试之间的缓存（在我看来，这是一个可怕的bug）。默认情况下，它无法重新读取文件，因此可能会忽略已发生的更改。我在这里提供了更多详细信息：Rails tutorial: undefined method

失败/错误：sign_in用户未定义方法`sign_in'
