所以我一直在尝试跟随rails教程，但我一直坚持让标题略显动态。一旦我到达this part并运行
$ bundle exec rspec spec/requests/static_pages_spec.rb
我收到以下错误

这就是我的“家庭”，“帮助”和“关于”视图。
主页

这是我的应用程序视图

我的静态页面规范
require 'spec_helper'
describe "Static pages" do
describe "Home page" do
it "should have the content 'Sample App'" do
visit '/static_pages/home'
expect(page).to have_content('Sample App')
end
it "should have the title 'Home'" do

如下所示更改您的视图（在第一行提供之前请注意=）。为所有三个观点做同样的事情
主页
<%= provide(:title, 'Home') %>
<h1>Sample App</h1>
<p>
This is the home page for the
<a href="http://railstutorial.org/">Ruby on Rails Tutorial</a>
sample application.
</p>

您是否尝试过手动访问每个页面并亲自检查标题？
我把你提供的所有东西都粘贴到了一个项目中（我不久前做了教程，所以我已经设置了一个static_pages控制器）并且所有这些测试都通过了。我会说你可能混淆了你的视图的文件名，或路由文件中的名字，但是内容测试正在传递，所以不可能。我猜你的一个文件可能是由编辑器以错误的编码保存的，或者其他类似的东西。另外，在运行测试之前，请检查您是否已保存所有文件。
另请注意，=不需要<% provide ...，因此您可能应该将其从您的视图中删除。
答案 2 :(得分：0)
我想您可能忘记将“联系”页面添加到routes.rb文件中，如下所示：
SampleApp::Application.routes.draw do
get "static_pages/home"
get "static_pages/help"
get "static_pages/about"
get "static_pages/contact"

试试这个：
require 'spec_helper'
describe "Static pages" do
let(:base_title) { "Ruby on Rails Tutorial Sample App" }
describe "Home page" do
it "should have the content 'Sample App'" do
visit '/static_pages/home'
expect(page).to have_content('Sample App')
end
it "should have the title 'Home'" do
visit '/static_pages/home'
#expect(page).to have_title("#{base_title} | Home")
page.should have_title("#{base_title} | Home")
end
end
describe "Help page" do
it "should have the content 'Help'" do
visit '/static_pages/help'
expect(page).to have_content('Help')
end
it "should have the title 'Help'" do
visit '/static_pages/help'
#expect(page).to have_title("#{base_title} | Help")
page.should have_title("#{base_title} | Help")
end
end
describe "About page" do
it "should have the content 'About Us'" do
visit '/static_pages/about'
expect(page).to have_content('About Us')
end
it "should have the title 'About Us'" do
visit '/static_pages/about'
page.should have_title("#{base_title} | About Us")
end
end
describe "Contact page" do
it "should have the content 'Contact'" do
visit '/static_pages/contact'
expect(page).to have_content('Contact')
end
it "should have the title 'Contact'" do
visit '/static_pages/contact'
# expect(page).to have_title("#{base_title} | Contact")
page.should have_title("#{base_title} | Contact")
end
end
end
<!DOCTYPE html>
<html>
<head>
