我开始使用 Rspec，但是当我运行时bundle exec rspec我收到一个错误
/spec/requests/pages_spec.rb:20:in `block (2 levels) in <top (required)>': undefined local
variable or method `root_path' for #<Class:0x00000102e46850> (NameError)
我没有运行 Spork 或 Guard，因此以下问题不适用
未定义的局部变量或方法“root_path”（Rspec Spork Guard） https://stackoverflow.com/questions/14871918/undefined-local-variable-or-method-root-path-rspec-spork-guard
我已经添加了config.include Rails.application.routes.url_helpers in my spec_helper.rb文件，但这没有帮助。未定义的局部变量或方法“root_path”Hartl 的教程第 5.3.2 章 https://stackoverflow.com/questions/12240868/undefined-local-variable-or-method-root-path-hartls-tutorial-chapter-5-3-2
Here's pages_spec.rb
require 'spec_helper'
describe "Pages" do
describe "navigation" do
def self.it_should_be_on(path_name, value=nil)
before { visit path_name }
it "should be on #{path_name}" do
page.should have_link('Home')
page.should have_link('Inventory')
page.should have_link('FAQ')
page.should have_link('About Us')
page.should have_link('Location')
page.should have_link('Contact Us')
# page.should have_link('Login')
end
end
it_should_be_on root_path
it_should_be_on faq_path
it_should_be_on about_path
it_should_be_on location_path
it_should_be_on contact_path
# it_should_be_on login_path
end
end
spec_helper.rb

Update在阅读了shared_examples之后，我成功地尝试了这个。有没有更好的方法来编写这个测试？我最终将页面分成单独的页面，例如主页等。
require 'spec_helper'
describe "Pages" do
subject { page }
shared_examples "navigation" do |path_name|
before { visit send( path_name) }
describe "navigation links should be on #{path_name}" do
it { should have_link('Home') }
it { should have_link('Inventory') }
it { should have_link('FAQ') }
it { should have_link('About Us') }
it { should have_link('Location') }
it { should have_link('Contact Us') }
# it { should have_link('Login') }
end
end
describe "Home Page" do
include_examples "navigation", :root_path
end
end
