我正在尝试遵循 Michael Hartl 的Rails 3 教程,但遇到了一个在其他地方找不到解释的错误。在第 9.2.1 节下,我在尝试为尝试更新个人资料页面的未登录用户运行测试时遇到错误。
describe "submitting to the update action" do
before { put user_path(user) }
specify { response.should redirect_to(signin_path) }
end
我得到的错误是“#(NameError)的未定义局部变量或方法'响应'”。这是对“bundle exec rspec spec/”的回应。当我注释掉违规行时,所有测试都会实例化并通过。我试过用“response.body”和“page”之类的东西替换“response”,但似乎都没有帮助。
我不确定问题出在哪里,因为随着我继续学习本教程,类似的块正在顺利通过。
这是完整的错误文本:

我很确定这不是某个地方的错字,但这是有问题的文件(authentication_pages_spec.rb)。(have_title() 是我在这里找到的一种修复错误的方法,因为显然 have_selector('title',...) 不再是有效的语法。)
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_title('Sign in') }
end
describe "signin" do
before { visit signin_path }
describe "with invalid information" do
before { click_button "Sign in" }
it { should have_title('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_title(user.name) }
it { should have_link('Profile', href: user_path(user)) }
it { should have_link('Settings', href: edit_user_path(user)) }
it { should have_link('Sign out', href: signout_path) }
it { should_not have_link('Sign in', href: signin_path) }

it { should have_link('Sign in') }
end
end
end

end
