如何在Rails测试中要求宝石？

如何解决如何在Rails测试中要求宝石？

您如何测试gem功能？我试图弄清楚为什么有些东西无法按照文档建议的方式工作，并设置了自己的these版本。但是我的测试失败了：

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

解决方法

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

Bundler.require(:default)
