Zeus 的一些单独测试快如闪电，而另一些则非常慢。

如果我做：

time rspec spec/

结果是：

Finished in 35.36 seconds
220 examples, 0 failures

real    0m59.018s
user    0m43.723s
sys 0m2.495s

但如果我使用宙斯：

time zeus rspec spec/

结果是：

Finished in 7 minutes 9 seconds
220 examples, 0 failures

real    7m13.053s
user    0m0.279s
sys 0m0.047s

请注意两者中的“用户”和“系统”时间，这与我的预期一致。然而，与“真实”时代所显示的内容存在重大脱节。

这是怎么回事？

编辑：下面是我的 spec_helper.rb 文件：

require File.expand_path("../../config/environment", __FILE__)
require 'rubygems'
require 'shoulda-matchers'

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

def spork?
  defined?(Spork) && Spork.using_spork?
end

def setup_environment
  # This file is copied to spec/ when you run 'rails generate rspec:install'
  ENV["RAILS_ENV"] ||= 'test'

  if spork?
    ENV['DRB'] = 'true'
    Spork.trap_method(Rails::Application::RoutesReloader, :reload!)
  end

  end

  OmniAuth.config.test_mode = true
end

prefork = lambda {

if defined?(Zeus)
  prefork.call
  $each_run = each_run
  class << Zeus.plan
    def after_fork_with_test
      after_fork_without_test
      $each_run.call
    end
    alias_method_chain :after_fork, :test
  end
# Same with spork.
elsif ENV['spork'] || $0 =~ /\bspork$/
  require 'spork'
  Spork.prefork(&prefork)
  Spork.each_run(&each_run)
else
  prefork.call
  each_run.call
end

spec_helper.rb 中的“要求”太多。你应该把它们放在你的 Gemfile 中：

group :test do    
    gem 'shoulda-matchers'
    gem 'database_cleaner'
    gem 'selenium-webdriver'
    gem 'timecop' 
    # and so on
end
