我试图在终端中使用以下命令在我的第一个Rails应用程序中运行测试：
rspec spec/
但这只会导致以下错误：
Exception encountered: #<NameError: uninitialized constant PagesController>

我可以在浏览器中成功运行该站点，并且“ Spork准备就绪并且正在监听”，这使我认为我正在运行的Gems，RSpec，Spork或...有问题吗？我编写的PagesController和RSpec测试不是基于RailsTutorial.org书。我很茫然。
这是我的Gemfile：

gem 'spork', '0.9.0.rc2'

是否有人有任何想法，或者我可以通过提供更多信息来帮助您？我是Rails的新手，时不时地回到它上面，然后在再次放弃之前似乎遇到了问题...
更新我的Spec / spec_helper.rb文件：
require 'rubygems'
require 'spork'
Spork.prefork do
# Loading more in this block will cause your tests to run faster. However,
# if you change any configuration or code from libraries loaded here, you'll
# need to restart spork for it take effect.
ENV["RAILS_ENV"] ||= 'test'
unless defined?(Rails)
require File.dirname(__FILE__) + "/../config/environment"
end
require 'rspec/rails'
# Requires supporting files with custom matchers and macros, etc,
# in ./support/ and its subdirectories.
Dir["#{File.dirname(__FILE__)}/support/**/*.rb"].each {|f| require f}
Rspec.configure do |config|
# == Mock Framework
#
# If you prefer to use mocha, flexmock or RR, uncomment the appropriate line:
#
# config.mock_with :mocha
# config.mock_with :flexmock
# config.mock_with :rr
config.mock_with :rspec
config.fixture_path = "#{::Rails.root}/spec/fixtures"
# If you're not using ActiveRecord, or you'd prefer not to run each of your
# examples within a transaction, comment the following line or assign false
# instead of true.
config.use_transactional_fixtures = true
### Part of a Spork hack. See http://bit.ly/arY19y
# Emulate initializer set_clear_dependencies_hook in
# railties/lib/rails/application/bootstrap.rb
ActiveSupport::Dependencies.clear
end
end
Spork.each_run do
end
这是除去spec_helper的内容时来自Terminal的输出：
No DRb server is running. Running in local process instead ...

最佳答案
原来，问题是由不同模型中的错误验证规则引起的。花费了很多随机的想法和尝试，但最终还是没有得到错误消息的帮助而到达目的地。
