.env 没有被加载到 Rails 的测试环境中，使用 rspec

Question

I am using gem 'dotenv-rails', '~> 0.9.0' to load environment variables into a Rails 4.0.5 app. I have a .env file along with a .env.test. All is working well in development, however when it comes to testing, which I do with rspec, it is failing to set the environment variables.

I have gone into Rails console in testing environment and I can see they are set to nil.

Any tips on how to get dotenv to load in testing?

Answer 1

This is a late answer, but for anyone who may find it helpful, add this to spec_helper.rb

require 'dotenv'
Dotenv.load('.env')

Also, Dotenv.load can accept a list, for example:

Dotenv.load(
  '.env.local',
  '.env.test',
  '.env'
)

Answer 2

将此行放在 rspec 设置中的Dotenv::Railtie.load或要加载 dot env 文件的任何页面中。

Answer 3

Dotenv.load(File.expand_path("../../.env.#{Rails.env}", __FILE__))

在研究 Paritosh 的回答后，我发现需要为每个环境指定文件。

Answer 4

If you have test specific environemnt config, You can use Dotenv.overload to overwrite other env config. Just add the following to your spec_helper.rb or rails_helper.rb .

require "dotenv"
Dotenv.overload ".env.test" 
Dotenv.overload ".env.test.local"
