Question

我是rails的新手，并开始了一个新项目。我有rspec2和黄瓜与我的测试工作没有问题。但是，如果我尝试添加guard-rspec和guard-cucumber，则会导致我的规范和集成测试失败。虽然，即使安装了防护装置，如果我手动运行rspec和黄瓜，测试都会成功。

我已添加到我的gemfile：

gem 'guard-rspec'
gem 'guard-cucumber'
gem 'growl', :require => false if RUBY_PLATFORM =~ /darwin/i
gem 'rb-fsevent', :require => false if RUBY_PLATFORM =~ /darwin/i

我跑了：

bundle
guard init rspec
guard init cucumber

然后当我守卫时，我得到了rspec失败：

看起来Guard似乎在某处弄乱我的工厂数据，因为以“the body必须超过50个字符”开头的文本在我的factory_girl工厂定义中。

修改我发现rake如何调用rspec，而不是后卫。为什么会这样？

Answer 1

看起来你在测试之间清理数据的方式不起作用。

您是否可以在之前（：all）调用中创建数据？

Rake spec调用（以及其他内容）rake db：test：prepare，它将删除并重新构建数据库。呼叫守卫不会调用rake db：test：prepare。这就是你在数据库中看到不同状态的原因。

Answer 2

我有类似的问题＆amp;我花了一段时间才弄明白，所以我想我会发帖。我的所有测试都是使用Rspec，但不是后卫，因为数据库状态有些不同。

我好像需要数据库清理工具，但是当我合并代码时

RSpec.configure do |config|
  config.before(:suite) do
       DatabaseCleaner.strategy = :truncation, {:except => %w[topics users]}
       DatabaseCleaner.clean
     end

     config.before(:each) do
       DatabaseCleaner.start
     end

     config.after(:each) do
       DatabaseCleaner.clean
     end

它不起作用。我编写了测试，以便在组的开头只有一个干净的数据库。我希望以某种方式清理每组测试之间的数据库，但我无法弄清楚如何实现比'test'更大但比'suite'更小的粒度。我通过更改测试来解决它，以便我使用干净的数据库开始每个测试。

有两个方面的变化 -

我不得不把呼叫转移到之前的FactoryGirl 声明
我不得不使用'let'语句来查找数据by_name 或其他一些字段，以便我可以验证页面上的数据。

我不确定是否有人会遇到相同的情况，但我最初想说的是，如果数据库清理程序不适合您，可能是因为您需要返回并更改您的规范文件。

rspec2 databasehelper guard

为什么警卫导致我的测试失败？
