Ruby on rails 我的rails测试产生了乱七八糟的输出

我刚刚赶上了一个新项目，

rake测试产生了大量乱七八糟的输出。为什么会这样？我尝试移除所有我不知道的宝石，但我的输出仍然是模糊的。我通过
bundle exec rake test
调用测试套件

示例输出-这是此类内容的页面

/Users/hendricius/.rbenv/versions/2.2.2/lib/ruby/gems/2.2.0/gems/activesupport-3.2.22.5/lib/active_support/file_update_checker.rb:98: warning: File.exists? is a deprecated name,
use File.exist? instead

.ruby version
文件中的ruby版本是
2.2.2
。安装的rails版本为
3.2.22.5

我的测试宝石是：

group :test, :development do
  # gem 'rack-mini-profiler'
  # gem 'minitest'
  gem 'minitest-rails'
  gem 'test-unit'
  gem 'shoulda'
  gem 'shoulda-matchers'
  gem 'fabrication'
  gem 'byebug'
end

然后我再次检查了我的
Rakefile
。它有以下内容：

# Add your own tasks in files placed in lib/tasks ending in .rake,
# for example lib/tasks/capistrano.rake, and they will automatically be available to Rake.

require File.expand_path('../config/application', __FILE__)

WooWoop::Application.load_tasks

task default: [:test]

我唯一能想到的是我的
测试助手
。我把内容贴在下面。看起来不错

ENV["RAILS_ENV"] = "test"
require File.expand_path("../../config/environment", __FILE__)
require "rails/test_help"
require "minitest/rails"
require "minitest/pride"
require 'shoulda'
require 'shoulda/matchers'
# $VERBOSE=nil

# ActiveRecord::Migration.check_pending!
ActiveSupport::TestCase.test_order = :random
# Protractor test or even some dirty debugging in the rails console on test environment
# might have left some garbage on the DB. Lets make sure we start with a clean state.
# parses the response and returns it.

唯一可以使输出静音的方法是使用
RUBYOPT=W0 TEST=TEST/unit/shop\u TEST.rb be rake TEST
。这是我使用rails 3的唯一方法吗

更新：

我现在尝试降级到ruby 2.0.0

我仍然收到很多以前从未见过的奇怪警告

编辑：

我最终升级到rails 4。所有警告都已消失。
消除警告的三个（其他）选项：

降级Ruby直到警告消失。您使用的是Ruby 2.2之前创建的旧版本Rails
File.exists？
在Ruby 2.2之前的某个时候被弃用

在gem存储库中手动编辑有问题的行

在gem存储库中运行“大规模搜索并替换shell”命令：


…当然还有最后一个选择：升级Rails。
我降级到Ruby 2。现在我也收到了很多其他的警告。我怀疑我的测试有点疯狂<代码>（评估）：11：警告：实例变量@opening\u hours\u monday\u from not initialized

例如。@Hendrik Ouch..听起来很复杂：-/您可以尝试将其作为

RUBYOPT=“-W0”rake test运行。见他问题的最后一行。关闭警告和降级软件是最后的手段。我希望升级是可能的。您将面临巨大的风险。项目以前使用过哪个Ruby版本？为什么不使用与原始项目中相同的版本？不要给自己制造太多的麻烦。那是
2.0.0-p481
。我来试一试。我现在还记得升级的原因：
警告：ruby-2.0.0-p481已经过时，现在不受支持。它不再接收错误修复或关键安全更新。
