我正在将 Rspec 测试添加到以前没有 rspec 或根本没有自动化测试的项目中。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'

主要问题是我正在为一个根本不使用回形针的模型编写一个简单的测试。回形针用于另一个模型。我进行了广泛的研究,试图将 gem 包含在测试环境中,但似乎没有任何解决问题的方法。

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 包括以下内容:

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:

    C:/Users/MAC/.pik/rubies/Ruby-192-p290/bin/ruby.exe -S rspec ./spec/models/filter_category_spec.rb ./spec/models/filter_spec.rb

       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

关于我应该怎么做才能使其正常工作的任何想法?

编辑似乎问题出现在加载 spec_helper.rb 之前如果我对此文件进行更改,例如故意添加错误,则没有任何反应,并且上述问题一直在发生。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 上的回形针 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]

不知道如何在不从测试环境中跳过 Paperclip 的情况下解决这个问题。

在我看来,问题出在 shoulda-matchers 和回形针上

添加到您的 spec_helper.rb 文件

require "paperclip/matchers"

低于你所在的位置

require "capybara/rspec"

并添加

config.include Paperclip::Shoulda::Matchers

以下

RSpec.configure do |config|    

查看回形针的 shoulda-matchers 文档

希望这可以帮助

我在尝试在具有 ActiveRecord 但没有 Rails 的 gem 中使用 Paperclip 时遇到了这个问题。spec/support/paperclip.rb我可以通过添加具有以下内容的文件来解决此问题以进行测试:

require 'paperclip/railtie'

RSpec.configure do |config|
  # Bind paperclip to enable ActiveRecord #has_attached_file method
  Paperclip::Railtie.insert
end

正如还建议的那样,这是添加config.include Paperclip::Shoulda::Matchers.

但我使用的是 Rails 4.2 和 Rspec 3,所以我认为加载的顺序与你的有很大不同。
