Question

突然每当我运行'rake test'或'捆绑exe rake test'时，我都会收到以下错误。

NameError: uninitialized constant FactoryGirl

在有人告诉我将require 'factory_girl'添加到我的test_helper.rb文件之前，同一个更新的分支正在另一台计算机上运行测试而没有任何问题。

我还是尝试添加require 'factory_girl'。然后它引发了另一个错误NameError: uninitialized constant Faker，所以我添加了require 'faker'并且总是需要它，并且该项目的测试总是正常工作而没有所有这些要求。

可能有用的信息：

Ubuntu 16.10
Rails 5.1.1
Ruby 2.3.3（使用rbenv）
我使用的是minitest，而不是RSPEC

错误包括跟踪：

** Invoke test (first_time)
** Execute test
rake aborted!
NameError: uninitialized constant FactoryGirl

有任何线索吗？

Answer 1

好的，所以当我放弃时，我发现了问题。

tl; dr：必须从RAILS_ENV=development

中删除.rbenv-vars

完整答案：

测试宝石在一个组中只能在这样的测试环境中运行：

group :test do
  # Call 'byebug' anywhere in the code to stop execution and get a debugger console
  gem 'byebug', platform: :mri
  gem 'faker'
  gem 'cpf_faker'
  gem 'factory_girl'
  gem 'capybara'
  gem 'minitest-capybara'
  gem 'poltergeist'
  gem "capybara-webkit"
  gem 'selenium-webdriver'
  gem 'minitest-rails'
end

事情是......我每天都会使用gem来运行某些任务，但是无论什么时候都无法找到它正在运行的环境，所以我在{{1}中使用了RAILS_ENV = development文件。

因此，即使.rbenv-vars在开发环境中运行，我也不知道为什么会发生这种情况。

Rails测试似乎没有加载任何类，NameError：未初始化的常量
