Rspec 未定义的局部变量或方法 root_path [英] Rspec undefined local variable or method root_path
问题描述
我开始使用 Rspec，但是当我运行 bundle exec rspec 时出现错误
I'm starting to use Rspec, but when I run bundle exec rspec I get an error
/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，所以下面的问题不适用
I do not have Spork or Guard running so the question below shouldn't apply
未定义的局部变量或方法`root_path'(Rspec Spork Guard)
我在我的 spec_helper.rb 文件中添加了 config.include Rails.application.routes.url_helpers，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
I have added config.include Rails.application.routes.url_helpers in my spec_helper.rb file, but that did not help.
undefined local variable or method `root_path' Hartl's Tutorial Chapter 5.3.2
这是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
# This file is copied to spec/ when you run 'rails generate rspec:install'
ENV["RAILS_ENV"] ||= 'test'
require File.expand_path("../../config/environment", __FILE__)
require 'rspec/rails'
require 'rspec/autorun'

# Checks for pending migrations before tests are run.
# If you are not using ActiveRecord, you can remove this line.
ActiveRecord::Migration.check_pending! if defined?(ActiveRecord::Migration)

# If you prefer to use mocha, flexmock or RR, uncomment the appropriate line:

config.fixture_path = "#{::Rails.root}/spec/fixtures"

config.order = "random"
config.include Capybara::DSL
config.include Rails.application.routes.url_helpers

更新在阅读了 shared_examples 之后，我成功地尝试了这一点.有没有更好的方法来编写这个测试?我最终将页面分离成单个页面，如主页等.
Update After reading about shared_examples, I tried this out successfully. Is there a better way to write this test? I ended up separating out the pages into individual pages like Home page etc.
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
推荐答案
要保存您的结构 - 您可以像这样更改代码:
To save your structure - you can change the code like this:
require 'spec_helper'
describe "Pages" do
describe "navigation" do
shared_examples_for 'main page' do |path_name|
before { visit send(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_behave_like 'main_page', :root_path
it_should_behave_like 'main_page', :faq_path
it_should_behave_like 'main_page', :about_path
it_should_behave_like 'main_page', :location_path
it_should_behave_like 'main_page', :contact_path
# it_should_behave_like 'main_page', :login_path
end
end
因为路径未在规范中的类级别定义"(c)您不能在规范类中调用路径方法.它应该在 it 块中.而且你的结构并不完美.如果您想避免重复，最好将代码放在模块中然后包含它.
because "paths are not defined at the class level in specs"(c)
You cannot call path methods in spec class. It should be in it block.
And your structure is not perfect. It will be better to put code in modules and then include it, if you want to avoid the duplication.
