我是 ruby​​/rails 的新手，目前正在将 railstutorial 书作为大学课程的一部分。我正在使用 ubuntu 11.04、ruby 1.9.2p290 和 Rails 3.0.9、watchr (0.7)、rspec (2.6.0)、rspec-formatter-webkit (2.1.3) 和 spork (0.9.0.rc)。

在 github 上我遇到了这个gem，我认为使用它会非常好。所以基本上我想要实现的是持续的自动化测试，如果完成了通知，并从中生成漂亮的 html 输出。

所以我尝试的是我写了这个观察者脚本：

require 'nokogiri'
require 'open-uri'

watch("spec/.*/*_spec.rb") do |match|
  run_spec match[0]
end

watch("app/(.*/.*).rb") do |match|
  run_spec %{spec/#{match[1]}_spec.rb}
end

def run_spec(file)
  unless File.exist?(file)
    puts "#{file} does not exist"
    return
  end

puts "Running #{file}"
result = `rspec -r rspec/core/formatters/webkit -f RSpec::Core::Formatters::WebKit #{file}`
File.open('out.html', 'w') do |f|
  f.puts result
end
notify(result)
puts "DONE"
end

def send_notify title, msg, img, pri='low', time=5000
  `notify-send -i #{img} -u #{pri} -t #{time} '#{msg}'`
end

def notify(result)
  output = result
  doc = Nokogiri::HTML(result)
  doc.xpath('//div[@id = "summary"]').each do |node|
    output = node.text.split.join(" ")
  end
  folder = "~/Pictures/autotest/"
  if output =~ /([123456789]|[\d]{2,})\sfailed/
    send_notify "FAIL:", "#{output}", folder+"rails_fail.png", 'critical', 20000
  elsif output =~ /[1-9]\d*\spending?/
    send_notify "PENDING:", "#{output}", folder+"rails_pending.png", 'normal', 15000
  else
    send_notify "PASS:", "#{output}", folder+"rails_ok.png"
  end
end

处理通知，并在测试时生成输出。

如果我用 watchr 运行它，一切都很好并且工作正常，但是测试当然需要很长时间。

问题出现在这里：如果我尝试使用 spork 来加快测试速度，我会收到一堆错误，从 LoadError 开始：

Exception encountered: #<LoadError: no such file to load --  rspec/core/formatters/webkit>

作为一个新手，这当然不会对我说什么。

有没有办法克服这个问题（或者当然以任何其他方式产生结果）？

任何帮助是极大的赞赏 ：）

您可能会更幸运地直接运行 RSpec 运行程序，而不是直接运行，例如，

require 'rspec/core'
require 'rspec/core/formatters/webkit'

# ...then in #run_spec
puts "Running #{file}"
File.open( 'out.html', 'w' ) do |f|
  argv = [ '-f', 'RSpec::Core::Formatters::WebKit', file ]
  RSpec::Core::Runner.run( argv, f )
end
notify(result)
puts "DONE"

ActiveSupport 猴子（自由）修补的“Kernel.require”似乎与您提到的三个场景不同。

如果您弄清楚 ActiveSupport 找不到库的原因，我很乐意尝试在 WebKit 格式化程序中解决它。
