为什么警卫导致我的测试失败？

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,当我跑卫,我得到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.

编辑: 我发现rake如何调用rspec,而不是后卫.为什么会这样？

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(除其他外)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.
