Rails应用程序在测试运行时是否应加载其.env文件？

问题描述 投票：0回答：1

我的应用程序在运行其测试套件时应该调用Dotenv.load吗？

在运行我的测试套件时不调用Dotenv.load，rspec失败并显示错过环境密钥的错误。我已经粘贴了错误及其堆栈跟踪。

$ rspec

An error occurred while loading ./spec/requests/users/create_spec.rb.
Failure/Error: require File.expand_path('../../config/environment', __FILE__)

在Rails应用程序之外，您需要执行以下操作：

require 'dotenv/tasks'

task start: [:dotenv] do
  # this Rake tasks depends on the dotenv  loading task
  puts 'hi'
end

在Rails应用程序内：

因为你实际上在Rails应用程序中，我会确保你在你的Gemfile中使用dotenv-rails，而不仅仅是dotenv。前者将自动运行dotenv内容作为Rails启动例程的一部分
