Question

我尝试过两个书面指南和一个youtube视频（http://www.youtube.com/watch?v=8ZmawOCDeyo），他们要么跳过一个重要的步骤（或者它只适用于他们），但不适合我。

我创建了以下文件夹结构：

RubyBots\
  features\
    step_definitions\
      creating_a_vehicle_for_an_ai_bot_steps.rb
    support\
      env.rb
    creating_a_vehicle_for_an_ai_bot.feature
  vehicle.rb
  vehicle_factory.rb

creating_a_vehicle_for_an_ai_bot_steps.rb的内容：

Given /^I have vehicle factory$/ do
  @vehicle_factory = VehicleFactory.new
end

When /^I use it to build a basic vehicle$/ do
  @new_vehicle = @vehicle_factory.build
end

Then /^I should have receive a basic vehicle$/ do
  #test @new_vechile
end

vehicle_factory.rb的内容：

class VehicleFactory
    def initialize(name)
        p name
    end
end

env.rb档案的内容：

require 'vehicle_factory'
require 'vehicle'

我在Cucumber目录内的CMD窗口内执行RubyBots（没有参数），我收到以下错误：

no such file to load -- vehicle_factory (LoadError)
<internal:lib/rubygems/custom_require>:29:in `require'

C:/Ruby192/bin/cucumber:19:in `load'
C:/Ruby192/bin/cucumber:19:in `<main>'

如果从支持目录中删除env.rb文件，运行Cucumber时会出现以下错误：

    Scenario: Using a vehicle factory to build a basic vehicle # Features\creating_a_vehicle_for_an_ai_bot.feature:6
Given I have vehicle factory                             # Features/creating_a_vehicle_for_an_ai_bot_steps.rb:1
    uninitialized constant Object::VehicleFactory (NameError)
    ./Features/creating_a_vehicle_for_an_ai_bot_steps.rb:2:in `/^I have vehicle factory$/'
    Features\creating_a_vehicle_for_an_ai_bot.feature:7:in `Given I have vehicle factory'
When I use it to build a basic vehicle                   # Features/creating_a_vehicle_for_an_ai_bot_steps.rb:5
Then I should have receive a basic vehicle               # Features/creating_a_vehicle_for_an_ai_bot_steps.rb:9

Failing Scenarios:
cucumber Features\creating_a_vehicle_for_an_ai_bot.feature:6 # Scenario: Using a vehicle factory to build a basic vehicle

我已经尝试了所有我能想到的东西而且我的google-fu让我失望了 - 我希望这是非常重要的事情，所以我不会感到尴尬，但很容易修复，所以我可以继续前进！：）

感谢您的帮助！

您的课程名为VehicleFactory，但您尝试在creation_a_vehicle_for_an_ai_bot_steps.rb中致电vehicle_factory.new。

另外，我相信Cucumber期望一个特定的目录结构：

RubyBots/
  features/
    step_definitions/
      creating_a_vehicle_for_an_ai_bot_steps.rb
    support/
      env.rb
    creating_a_vehicle_for_an_ai_bot.feature

您需要适当地从env.rb中获取自己的文件。 Ruby不适合你的任何路径。在my blog post中描述了一种基于符号名称自动要求文件的方法（Rails的方式）（它依赖于ActiveSupport 2.3，但对于当前版本应该类似）。

如何设置使用Cucumber测试的类的路径？
