＃< Class：XYZ>的未定义方法'visit' （NoMethodError）[rspec] [英] Undefined method 'visit' for #<Class:XYZ> (NoMethodError) [rspec]

问题描述

当我尝试运行rspec测试时遇到以下错误：

I'm getting the following error when I try to run an rspec test:

/srv/offerme/spec/requests/static_pages_spec.rb:13: undefined method `visit' for #<Class:0xb3436684> (NoMethodError)
from /var/lib/gems/1.8/gems/rspec-core-2.11.1/lib/rspec/core/example_group.rb:238:in `module_eval'

我收到此错误的文件是这样的（spec / requests / static_pages_spec.rb）：

The file I get this error in looks like this (spec/requests/static_pages_spec.rb) :

require 'spec_helper'

describe "StaticPages" do
include Capybara::DSL
  describe "GET /static_pages" do
    it "works! (now write some real specs)" do
      # Run the generator again with the --webrat flag if you want to use webrat methods/matchers
      get static_pages_index_path
      response.status.should be(200)
    end 
  end 
  describe "Home page" do
    visit 'static_pages/home'
    page.should have_content('OfferMe')
  end 

end

我的spec_helper.rb文件如下：

My spec_helper.rb file looks like this:

# 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'
require 'capybara/rspec'

# Requires supporting ruby files with custom matchers and macros, etc,
# in spec/support/ and its subdirectories.
Dir[Rails.root.join("spec/support/**/*.rb")].each {|f| require f}

RSpec.configure do |config|
  # ## Mock Framework
  #
  # If you prefer to use mocha, flexmock or RR, uncomment the appropriate line:
  #
  # config.mock_with :mocha
  # config.mock_with :flexmock
  # config.mock_with :rr

  # Remove this line if you're not using ActiveRecord or ActiveRecord fixtures
  config.fixture_path = "#{::Rails.root}/spec/fixtures"

  # If you're not using ActiveRecord, or you'd prefer not to run each of your
  # examples within a transaction, remove the following line or assign false
  # instead of true.
  config.use_transactional_fixtures = true

  # If true, the base class of anonymous controllers will be inferred
  # automatically. This will be the default behavior in future versions of
  # rspec-rails.
  config.infer_base_class_for_anonymous_controllers = false

  # Run specs in random order to surface order dependencies. If you find an
  # order dependency and want to debug it, you can fix the order by providing
  # the seed, which is printed after each run.
  #     --seed 1234
  config.order = "random"
  config.include Capybara::DSL
end
module ::RSpec::Core
class ExampleGroup
include Capybara::DSL
include Capybara::RSpecMatchers
end
end

最后，我的Gemfile看起来像这样：

And, finally, my Gemfile looks like this:

source 'https://rubygems.org'

gem 'rails', '3.2.7'

# Bundle edge Rails instead:
# gem 'rails', :git => 'git://github.com/rails/rails.git'

group :development, :test do
  gem 'sqlite3'
  gem 'rspec-rails'
end

group :test do
  gem 'capybara'
end

gem 'json'

# Gems used only for assets and not required
# in production environments by default.
group :assets do
  gem 'sass-rails',   '~> 3.2.4'
  gem 'coffee-rails', '~> 3.2.2'

  # See https://github.com/sstephenson/execjs#readme for more supported runtimes
  # gem 'therubyracer', :platforms => :ruby

  gem 'uglifier', '>= 1.0.3'
  gem 'twitter-bootstrap-rails'
end

gem 'jquery-rails'

# To use ActiveModel has_secure_password
# gem 'bcrypt-ruby', '~> 3.0.0'

# To use Jbuilder templates for JSON
# gem 'jbuilder'

# Use unicorn as the app server
# gem 'unicorn'

# Deploy with Capistrano
# gem 'capistrano'

# To use debugger
# gem 'ruby-debug'

gem 'therubyracer', '0.10.1'
gem 'libv8'
gem 'webrat'

我已经看到了这个GitHub issue 并有尝试了一些变通办法，并研究了与类似问题有关的其他StackOverflow问题（这就是为什么某些代码看上去多余/骇客的原因）。但是，它们都没有起作用。请帮忙！

I have seen this GitHub issue and have tried some of the workarounds as well as looked at some other StackOverflow questions pertaining to the similar issue (that's why some of the code looks redundant/hacky). However, none of them have worked yet. Please help!

推荐答案

更新：

问题是您在 it 块之外调用 visit ，在这里：

The problem is that you're calling visit outside of an it block, here:

describe "Home page" do
  visit 'static_pages/home'
  page.should have_content('OfferMe')
end

将这些中间行包装在 it 块中：

Wrap those middle lines in an it block:

describe "Home page" do
  it "has a homepage" do
    visit 'static_pages/home'
    page.should have_content('OfferMe')
  end
end

原始答案：

我可能错了，但我相信您必须包括水豚

I could be wrong, but I believe you have to include capybara in both the test and development sections of your Gemfile.

尝试将Gemfile的该部分更改为：

Try changing that section of your Gemfile to this:

group :development, :test do
  gem 'sqlite3'
  gem 'rspec-rails'
  gem 'capybara'
end
