Michael Hartl的Ruby on Rails教程。 第9章中的测试失败

我是Michael Hartl的Tuby on Rails教程的新手，我在第9章的测试中有几个失败的项目。

运行RSPEC测试返回：

sis-macbook-pro:sample_app Lagaspi$ bundle exec rspec spec/ ...................................FF................................ Failures: 1) Authentication authorization in the Users controller visiting the edit page Failure/Error: before { visit edit_user_path(user) } NameError: undefined local variable or method `user' for # # ./spec/requests/authentication_pages_spec.rb:72:in `block (5 levels) in ' 2) Authentication authorization in the Users controller submitting to the update action Failure/Error: before { put user_path(user) } NameError: undefined local variable or method `user' for # # ./spec/requests/authentication_pages_spec.rb:77:in `block (5 levels) in ' Finished in 1.85 seconds 69 examples, 2 failures Failed examples: rspec ./spec/requests/authentication_pages_spec.rb:73 # Authentication authorization in the Users controller visiting the edit page rspec ./spec/requests/authentication_pages_spec.rb:78 # Authentication authorization in the Users controller submitting to the update action 

我的authentication_pages_spec.rb

 require 'spec_helper' describe "Authentication" do subject { page } describe "signin page" do before { visit signin_path } it { should have_selector('h1', text: 'Sign in') } it { should have_selector('title', text: 'Sign in') } end describe "signin" do before { visit signin_path } describe "with invalid information" do before { click_button "Sign in" } it { should have_selector('title', text: 'Sign in') } it { should have_selector('div.alert.alert-error', text: 'Invalid') } describe "after visiting another page" do before { click_link "Home" } it { should_not have_selector('div.alert.alert-error') } end end describe "with valid information" do let(:user) { FactoryGirl.create(:user) } before { sign_in user } it { should have_selector('title', text: user.name) } it { should have_link('Profile', href: user_path(user)) } it { should have_link('Sign out', href: signout_path) } it { should have_link('Settings', href: edit_user_path(user)) } it { should have_link('Users', href: users_path) } it { should_not have_link('Sign in', href: signin_path) } describe "followed by signout" do before { click_link "Sign out" } it { should have_link('Sign in') } end end end describe "authorization" do describe "for non-signed-in users" do let(:user) { FactoryGirl.create(:user) } describe "when attempting to visit a protected page" do before do visit edit_user_path(user) fill_in "Email", with: user.email fill_in "Password", with: user.password click_button "Sign in" end describe "after signing in" do it "should render the desired protected page" do page.should have_selector('title', text: 'Edit user') end end end end describe "in the Users controller" do describe "visiting the edit page" do before { visit edit_user_path(user) } it { should have_selector('title', text: 'Sign in') } end describe "submitting to the update action" do before { put user_path(user) } specify { response.should redirect_to(signin_path) } end end end describe "as wrong user" do let(:user) { FactoryGirl.create(:user) } let(:wrong_user) { FactoryGirl.create(:user, email: "[e-mail]") } before { sign_in user } describe "visiting Users#edit page" do before { visit edit_user_path(wrong_user) } it { should_not have_selector('title', text: full_title('Edit user')) } end describe "submitting a PUT request to the Users#update action" do before { put user_path(wrong_user) } specify { response.should redirect_to(root_path) } end end end 

这是上面的第73行

 it { should have_selector('title', text: 'Sign in') } 

从上面的第78行

 specify { response.should redirect_to(signin_path) } 

有任何想法吗？ 我真的不知道这意味着什么。谢谢Si。

Answer 1

在第50行你有

 let(:user) { FactoryGirl.create(:user) } 

但是：当您到达第73行时，用户不再可用，因为您关闭了描述块：用户在第68行中定义。在第77行，您尝试再次使用它时也是如此。

我的建议是将let（：user）移动到规范的顶部，这样您只需要定义一次，而不是在整个规范中包含它。 如果做不到这一点，请在第71行再次定义它（ 描述“在用户控制器中”之后的行 ）

潜在的解决方案是在顶部定义let（：user）…..所以你只需要定义一次用户而不是每个块

 require 'spec_helper' describe "authentication" do subject { page } let(:user) { FactoryGirl.create(:user) } ...
