Ruby on Rails教程Michael Hartl。第8.29章失敗測試

我是通過Hartl工作的新手。到了第8章的最後，當我檢查我的瀏覽器登錄/註銷時，每件事情都顯得AOK。然而，當我運行這個測試：Ruby on Rails教程Michael Hartl。第8.29章失敗測試

Failed examples: 

rspec ./spec/requests/user_pages_spec.rb:48 # User pages signup with valid information after saving the user

我有一個想法，但我不能完全肯定。所以這裏是我的user_pages_spec.rb文件：

require 'spec_helper' 

describe "User pages" do 

subject { page } 

describe "signup page" do 
before { visit signup_path } 

it { should have_selector('h1', text: 'Sign up') } 
it { should have_selector('title', text: full_title('Sign up')) } 
end 

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

it { should have_selector('h1', text: user.name) } 
it { should have_selector('title', text: 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: "[email protected]" 
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 

    describe "after saving the user" do 
before { click_button submit } 
it { should have_link('Sign out') } 
    end 
end 
end 
end

capybara有一個名爲save_and_open_page的方法，您可以在「it」之前插入，以便在測試運行者看到它時打開頁面。使這樣的調試更容易一些。 –
