RSpec 1.x 至 RSpec 2.x（Rails 2.x 至 Rails 3.x）
我正在将 Rails 2.x 应用程序转换为 Rails 3.x。 Rails 2.x 项目的规范当前已全部通过。
然而，将规范移至 Rails 3.x 应用程序后，规范消失了，无法找到 Rails.root + '/lib'< 中定义的基类 (SmsCommand::Base) /代码> 目录。我尝试仅使用 rspec path_to_spec、rake spec 和 bundle exec rspec path_to_spec 运行规范，但均无济于事。
我担心这可能与目录嵌套有关。举个例子：
/spec/models/sms_commands/accept_spec.rb
是规范：
/app/models/sms_commands/accept.rb
Accept 类继承自 SmsCommand::Base ，它包含在：
/lib/sms_command.rb
似乎 Rails 自动加载器没有发生在规范中或者它根本不自动加载 /lib 目录。
rake spec 的输出是：
/Users/xxx/.rvm/gems/ruby-1.9.2-p180@a_project/gems/rspec-core 2.5.1/lib/rspec/core/backward_compatibility.rb:20:
in `const_missing': uninitialized constant Object::SmsCommand (NameError)
from /Users/xxx/Projects/a_project/app/models/sms_commands/accept.rb:2:in `<top (required)>'
每个规范所需的 My spec_helper 具有以下相关行：（我尝试使用手动 require 来强制解决该问题 对于 lib 目录中的每个 *.rb。）
ENV["RAILS_ENV"] ||= 'test'
Dir[File.expand_path(File.join(File.dirname(__FILE__),'..', 'lib','**','*.rb'))].each {|f| require f}
require File.expand_path(File.join(File.dirname(__FILE__),'..','config','environment'))
#require 'spec/autorun'
require 'spec/rails'
I am in the process of converting a Rails 2.x application to Rails 3.x. The Rails 2.x project's specs execute with all passing currently.
However after moving the specs to the Rails 3.x application the specs die, unable to find a base class (SmsCommand::Base) defined in the Rails.root + '/lib' directory. I have tried running the specs with just rspec path_to_spec, rake spec and bundle exec rspec path_to_spec all to no avail.
I am concerned that it may have to do with directory nesting. As an example:
/spec/models/sms_commands/accept_spec.rb
is the spec for:
/app/models/sms_commands/accept.rb
The Accept class inherits from SmsCommand::Base which is contained at:
/lib/sms_command.rb
It seems as though the Rails autoloader isn't happening for specs or its just not autoloading the /lib directory at all.
The output from rake spec is:
/Users/xxx/.rvm/gems/ruby-1.9.2-p180@a_project/gems/rspec-core 2.5.1/lib/rspec/core/backward_compatibility.rb:20:
in `const_missing': uninitialized constant Object::SmsCommand (NameError)
from /Users/xxx/Projects/a_project/app/models/sms_commands/accept.rb:2:in `<top (required)>'
My spec_helper which is required by each spec has the following pertinent lines: (I have tried to force the issue with the manual require for each *.rb in the lib directory.)
ENV["RAILS_ENV"] ||= 'test'
Dir[File.expand_path(File.join(File.dirname(__FILE__),'..', 'lib','**','*.rb'))].each {|f| require f}
require File.expand_path(File.join(File.dirname(__FILE__),'..','config','environment'))
#require 'spec/autorun'
require 'spec/rails'

...事实证明
/lib 默认情况下不会自动加载，并且无论出于何种原因，在application.rb中实际上都没有警告。添加
我的
Application解决了问题。From reading this:
https://rails.lighthouseapp.com/projects/8994/tickets/5218-rails-3-rc-does-not-autoload-from-lib
... it turns out that
/libisn't autoloaded by default and there's really no warning in theapplication.rbfor whatever reason.Adding
in my
Applicationfixed the problem.
