Rails 5.0.1 升级后 RSpec 测试套件未运行

Question

我们正在将 Rails 应用程序从 3.2 升级到 5.0。我们到了 4.2 并且有一个测试套件通过了 100%，我们现在在 5.0.1 并且测试套件抛出了一个参数错误。

运行rake spec:models时出现如下错误：

An error occurred while loading rails_helper.
Failure/Error: require File.expand_path("../config/environment", __dir__)

ArgumentError:
  wrong number of arguments (given 0, expected 2..3)

Ruby V 2.5.1 RSpec V 3.8

在开发环境中运行 rake db:migrate 任务完成，但是..

在测试环境中运行 db:migrate 后，出现以下错误：

ArgumentError: wrong number of arguments (given 0, expected 2..3)
/home/vagrant/rtest/config/initializers/load_rtest_config.rb:5:in `test'
/home/vagrant/rtest/config/initializers/load_rtest_config.rb:5:in `<top

环境.rb：

# Load the rails application
# require File.expand_path('../application', __FILE__) # RAILS 4.2
require_relative 'application'


# Initialize the rails application
# Changes for rtest upgrade
Rails.application.initialize!

load_rtest_config.rb：

require 'ostruct'
require 'yaml'

config = OpenStruct.new(YAML.load_file("#{Rails.root}/config/rtest.yml"))
::RTestConfig = OpenStruct.new(config.send(Rails.env))

::SummaryConfig = OpenStruct.new(YAML.load_file("# 
{Rails.root}/config/summary.yml"))

::LDAPConfig = OpenStruct.new(YAML.load_file("# 
{Rails.root}/config/ldap.yml"))

    load controller
  end
  Dir["#{Rails.root}/app/models//*.rb"].each do |model|
    load model
  end
  puts "Done"

  FactoryBot.reload
  Dir[Rails.root.join("spec/support/**/*.rb")].each do |f|
    require f

编辑：抱歉，如果问题不清楚，这是我的第一个问题，谢谢。

Answer 1

解决了！

问题出在这里：

ArgumentError: wrong number of arguments (given 0, expected 2..3)
/home/vagrant/rtest/config/initializers/load_rtest_config.rb:5:in `test'

“测试”这个词导致 ruby​​mine 认为它是一个需要 2..3 个参数的方法测试（不知道它是在哪里定义的）。

load_rtest_config：

config = OpenStruct.new(YAML.load_file("#{Rails.root}/config/rtest.yml"))
::RTestConfig = OpenStruct.new(config.send(Rails.env))

上面的 .send 方法没有正确传递字符串“test”。然而，它会通过“发展”。

修复：

::RTestConfig = OpenStruct.new(config[Rails.env])
