Rspec預計link_to沒有找到任何東西

Question

！我一直在閱讀Michael Hartl的RoR教程書，並且我在Rspec上停留了7次失敗。我一直在尋找3小時來發現錯誤，但我無法找到它。錯誤表示我沒有link_to退出（一個來自用戶頁面，一個來自編輯頁面），link_to更改以及一堆has_selector錯誤。這裏是rspec user_pages_spec.rb。我幾乎可以肯定的edit.html.erb和header.html中都很好，但如果沒有人看到什麼不對本rspec的不是生病後它

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_selector('h1', text: "Update your profile") } 
     it { should have_selector('title', text: "Edit user") } 
     it { should have_link('change', href: 'http://gravatar.com/emails') } 
    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_selector('title', text: new_name) } 
     it { should have_selector('div.alert.alert-success') } 
     it { should have_link('Sign out', href: signout_path) } 
     specify { user.reload.name.should == new_name } 
     specify { user.reload.email.should == new_email } 
    end

你錯過subject { page }剛下describe "edit" do。這可以讓你使用語法it { should ...。
