Question

我试着测试我的项目。之前它正在工作，我不知道每当我输入bundle exec rspec spec/它cannot load such file -- capybara/rspec (LoadError)时我做了什么。并且我需要一个建议，哪个适合在新手上测试我的MVC在ruby轨道上。

Gemfile:
------------

group :test do
  # Pretty printed test output
  gem 'turn', :require => false
  gem 'minitest'
  gem 'capybara', '1.1.2'
  gem 'rb-inotify', '0.8.8'
  gem 'libnotify', '0.5.9'
  gem 'guard-spork', '0.3.2'
  gem 'spork', '0.9.0'
  gem 'spork-testunit'
  gem 'guard-test'
  gem 'ruby-prof'
  gem 'factory_girl_rails', '1.4.0' 
  if RUBY_PLATFORM =~ /linux/
    gem 'capybara-webkit'
  end
  gem 'launchy'
end

group :development, :test do
  gem 'rspec-rails', '2.10.0'
  gem 'guard-rspec', '0.5.5'
end

spec_helper：

require 'rubygems'
#require 'factory_girl'
#uncomment the following line to use spork with the debugger
#require 'spork/ext/ruby-debug'


  ENV["RAILS_ENV"] ||= 'test'
  require File.expand_path("../../config/environment", __FILE__)
  require 'rspec/rails'
  require 'rspec/autorun'
  require 'capybara/rspec'
  require 'capybara/rails'

  # 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
  config.mock_with :rspec

  # 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 = false

  # 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

  #Capybara.default_driver = :selenium
  Capybara.javascript_driver = :webkit
end

提前致谢!!!

Answer 1

我希望你安装了所有必需的宝石？使用bundle install BTW你改变了Gemfile，在这种情况下你需要使用bundle install来安装Gems。

您可以查看gem list

提供的宝石列表

关于问题的第二部分，使用哪种测试API。这是选择的问题。您可以坚持使用rpsec，如果您发现它达不到您的期望，那么请注意改变。

Answer 2

尝试gem query --local查看已安装的宝石列表中是否显示capybara-screenshot。（出于某种原因，这为我提供了与gem list不同的列表。）

如果您没有看到，请尝试gem install capybara-screenshot。它不包含在capybara的安装中，因此仅在您的宝石列表中查看capybara是不够的！

我今天遇到了同样的问题，我通过以下方式解决了这个问题：

评论文件spec_helper.rb 下一个原料 require 'capybara/rspec' require 'capybara/rails'，
移除 /usr/local/rvm/gems/ruby-1.9.3-p327@olha/gems/capybara-webkit-1.1.0 来自我的硬盘空间。

`require'：无法加载这样的文件 - capybara / rspec（LoadError）

spec_helper：
