Question

我将Rspec测试添加到之前没有rspec的项目中，或者根本就是自动化测试。它在Windows 7机器上运行。当我运行rspec时，它显示错误：

undefined method `has_attached_file'

主要问题是我只为一个完全不使用Paperclip的模型编写了一个简单的测试。 Paperclip用于其他型号。我已经进行了广泛的研究，试图在测试环境中包含gem，但似乎没有解决问题。

当我运行rspec测试时，有没有办法跳过或强制包含回形针？

我的gemfile除其他外还有以下内容：

source 'http://rubygems.org'
ruby "1.9.2"
gem 'rails', '3.0.20'
...
gem "paperclip", :git => 'git://github.com/thoughtbot/paperclip.git'
gem 'aws-s3'
gem 'aws-sdk'
group :test, :development do
  gem 'rspec-rails', '~> 2.14.0'
end
group :test do
  gem 'sqlite3'
  gem 'capybara', '2.0'
  gem 'selenium-webdriver'
  gem 'shoulda-matchers'
  gem 'database_cleaner'
  gem 'launchy', '2.2.0'
  gem 'factory_girl_rails'
end

我运行rspec命令：

bundle exec rake spec

我收到以下错误：

       from C:/Avity/DS Candidates Tracking System/ds-cts/spec/models/filter_category_spec.rb:1:in `require'

我的spec_helper文件是：

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

  config.use_transactional_fixtures = false
  config.infer_base_class_for_anonymous_controllers = false
  config.order = "random"

  #Database cleaner
  config.before(:suite) do
    DatabaseCleaner.strategy = :truncation
  end

  config.before(:each) do
    DatabaseCleaner.start
  end

  config.after(:each) do
    DatabaseCleaner.clean
  end

  #Use chrome driver
  Capybara.register_driver :selenium do |app|
      Capybara::Selenium::Driver.new(app, :browser => :chrome)
    end
    Capybara.current_driver = :selenium_chrome
end

我应该怎样做才能使其正常运作？

编辑在加载spec_helper.rb之前似乎出现了问题如果我对此文件进行更改，例如故意添加错误，则不会发生任何事情，并且上述问题仍在继续。我必须运行测试的唯一方法是在我的模型上注释has_attached_file行，并将group选项添加到我的Gemfile上的paperclip gem，以避免在测试环境中使用它：

gem "paperclip", :git => 'git://github.com/thoughtbot/paperclip.git', :group=>[:development,:production]

如果不从测试环境中跳过Paperclip，不知道如何解决这个问题。

Answer 1

在我看来问题是与shoulda-matchers和paperclip一起使用

添加到spec_helper.rb文件

require "paperclip/matchers"

下面你在哪里

require "capybara/rspec"

并添加

config.include Paperclip::Shoulda::Matchers

以下

RSpec.configure do |config|

查看shoulda-matchers documentation for paperclip

希望这有帮助

Answer 2

我在尝试在具有ActiveRecord而不是Rails的gem中使用Paperclip时遇到了这个问题。我能够通过添加img.crossOrigin = "Anonymous";文件来解决这个问题：

spec/support/paperclip.rb

同样建议，这是添加require 'paperclip/railtie' RSpec.configure do |config| # Bind paperclip to enable ActiveRecord #has_attached_file method Paperclip::Railtie.insert end的好地方。

但是我使用Rails 4.2和Rspec 3，所以我认为加载的东西的顺序与你的不同。

Paperclip和Rspec的问题：未定义的方法`has_attached_file'
