我有一个研究案例项目，与Rails 4，RSpec，FactoryGirl，Faker合作...
但是 rspec 测试在开发环境中随机失败。我正在寻找很多，但如果有人能帮助我弄清楚，我将不胜感激。
以下是测试文件、工厂和模型的链接：
-
待测试型号：https://github.com/freaktags/core/blob/master/app/models/user.rb
-
用户工厂：https://github.com/freaktags/core/blob/master/spec/factories/users.rb
-
测试本身：https://github.com/freaktags/core/blob/master/spec/models/user_spec.rb
当它失败时，总是产生一个几乎像这样的堆栈：
Failure/Error: @chloe = FactoryGirl.create(:user)

您将区域设置更改为 rails 默认值以外的其他内容，并且收到无法转换为该区域设置的错误。
一个简单的解决方法是暂时将区域设置更改回默认值，这样您更有可能收到实际的错误消息（看起来activerecord试图告诉您一些事情，但它不知道如何用pt-BR说）。 它会用英语告诉你这个错误，但似乎你懂英语，所以这应该不是问题。
切换回所需的区域设置，错误不应再出现。
如果需要避免更改区域设置，则需要为特定错误添加适合所选区域设置的翻译。 其他地方有一些资源可以帮助完成此过程。 以下是一些相关信息的链接：

更新：在黑暗中拍摄，但您的特定错误可能与 FactoryGirl 在初始化过程中遇到问题有关。 这个答案看起来可能适用于你的问题：https://stackoverflow.com/a/11644746/1026898。
问题是Faker，它没有提供电子邮件和用户名值的控件。无论如何，Ecnalyr在找到问题方面帮助很大:)
