ruby-on-rails - Capybara javascript 驱动程序无法正常工作(env : Rspec, Spork、Capybara、Webkit)

Question

这是我在网上提出的第一个问题，所以请发表评论，我会尽力更新我的问题以澄清。

我对 Web 开发相当陌生，目前正在为公司项目开发测试套件。当我尝试对涉及 javascript 的函数进行集成测试时，它运行得很好。我尝试使用 webkit(从 gi​​t 捆绑)和 selenium。 Webkit 给出了以下错误消息。

Wrote response false "Unable to load URL: http://127.0.0.1:56618/ because of error loading http://127.0.0.1:56618/: Connection closed" 
Cleaning database...done
Received "Reset"

Wrote response true "" 
  should see invalid message (FAILED - 1)

 Capybara::Webkit::InvalidResponseError:
   Unable to load URL: http://127.0.0.1:56618/ because of error loading http://127.0.0.1:56618/: Connection closed

当使用 Selenium 时，FireFox 会提示:

Your Firefox profile cannot be loaded. It may be missing or inaccessible.

有人知道可能出现什么问题吗？ 提前致谢!

我的 sepc_helper.rb

Spork.prefork do
  ...
  ..
  .
  RSpec.configure do |config|
    config.use_transactional_fixtures = false
    config.before(:suite) { require "#{Rails.root}/db/seeds.rb" }
    config.before(:each) do
      if Capybara.current_driver == :rack_test
        DatabaseCleaner.strategy = :transaction                                                                               
      else
        DatabaseCleaner.strategy = :truncation
      end
      DatabaseCleaner.start
    end

    config.after(:each) do
      if Capybara.current_driver == :rack_test
        DatabaseCleaner.clean
      else
        DatabaseCleaner.clean
        load "#{Rails.root}/db/seeds.rb"
      end 
    end 

  end
end

Spork.each_run do
  ActiveRecord::Schema.verbose = false
  load "#{Rails.root.to_s}/db/schema.rb"
  Dir[Rails.root.join("spec/support/**/*.rb")].each {|f| require f}
end

我不确定，但你可以尝试一下，

在您的 spec_helper.rb 文件中添加以下代码

require 'spork'
Spork.prefork do

   # 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 'email_spec'


  # Add this to load Capybara integration:

  require 'capybara/rspec'
  require 'capybara/rails'

  # Database Cleaner
  #require 'database_cleaner'

  # DatabaseCleaner.strategy = :truncation


  # 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}

Spork.each_run do
end

做一件事取消注释数据库清理器。
