如何在 rails 测试中要求 gem？

Question

您如何测试 gem 功能？我试图弄清楚为什么有些东西没有按照文档建议的方式工作，并设置我自己的 these 版本。然而我的测试失败了：

19: ...
18: ...
#...etc....
5: from /Users/me/code/project/test/shrine_test.rb:5:in `<top (required)>'
4: from /Users/me/code/project/test/shrine_test.rb:5:in `require'
3: from /Users/me/.rvm/gems/ruby-2.5.0/gems/lockbox-0.4.8/lib/lockbox.rb:20:in `<top (required)>'
2: from /Users/me/.rvm/gems/ruby-2.5.0/gems/lockbox-0.4.8/lib/lockbox.rb:20:in `require'
1: from /Users/me/.rvm/gems/ruby-2.5.0/gems/lockbox-0.4.8/lib/lockbox/railtie.rb:1:in `<top (required)>'
/Users/me/.rvm/gems/ruby-2.5.0/gems/lockbox-0.4.8/lib/lockbox/railtie.rb:2:in `<module:Lockbox>': uninitialized constant Rails::Railtie (NameError)
Did you mean?  Rails

这是我的测试文件，shrine_test.rb:

 require "bundler/setup"
 Bundler.setup
 require "minitest/autorun"
 require "minitest/pride"
 require "lockbox" #this is the line 5 from above

 $logger = ActiveSupport::Logger.new(ENV["VERBOSE"] ? STDOUT : nil)
 require_relative "support/shrine"
 require_relative "support/active_record"
 Lockbox.master_key = SecureRandom.random_bytes(32)

class ShrineTest < Minitest::Test
 #tests here
end

假设 Gemfile 中的 gem 在默认组中（不在任何 group :environment do 块中），将 Bundler.setup 替换为

Bundler.require(:default)
