Rspec + FactoryGirl + Faker 测试随机失败

Question

我有一个研究案例项目，与 Rails 4，RSpec，FactoryGirl，Faker...

但是 rspec 测试在开发环境中随机失败。我正在搜索很多，但如果有人能帮我弄清楚，我将不胜感激。

以下是测试文件、工厂和模型的链接：

待测机型：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
自测：https://github.com/freaktags/core/blob/master/spec/models/user_spec.rb

当它失败时，总是产生一个堆栈，几乎像这样：

Answer 1

您将区域设置更改为 rails 默认设置以外的其他内容，并且收到没有翻译成该区域设置的错误。

一个简单的解决方法是暂时将语言环境更改回默认设置，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，但它没有我不知道在 pt-BR 中怎么说）。它会用英文告诉你这个错误，但看起来你懂英文所以应该不是问题。

修复错误，然后将语言环境切换回您想要的语言环境，错误应该不会再出现。

如果您需要避免更改区域设置，则需要为特定错误添加适合您选择的区域设置的翻译。其他地方的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 在初始化期间出现问题有关。 . .这个答案看起来可能可以解决您的问题：.

问题是 Faker，它没有提供对电子邮件和用户名值的控制。无论如何，Ecnalyr 在发现问题方面提供了很多帮助:)
