未初始化的常量(NameError)问题——如何包含一个类? [英] Uninitialized constant (NameError) problem - how to include a class?

问题描述

这是我的目录结构:

/features/ninja.feature
/features/step_definitions/ninja_steps.rb
/src/ninja.rb

当我跑步时

cucumber

在我的项目的根目录中，我得到一个 uninitialized string constant Ninja (NameError) 错误.我已经确定这是由我的 ninja_steps.rb 文件中的这一行引起的:

in the root of my project, I get an uninitialized string constant Ninja (NameError) error. I've determined it's caused by this line in my ninja_steps.rb file:

@ninja = Ninja.new :belt_level => belt_level

在我的 ninja.rb 文件中:

class Ninja
  def initialize (belt_level)
  end
end

我是否需要在 ninja_steps.rb 文件的顶部添加某种 require 或什么?我似乎无法弄清楚如何做到这一点，以免它爆炸.

Do I need to add some sort of require at the top of my ninja_steps.rb file, or what? I can't seem to figure out how to do that so that it doesn't bomb out.

推荐答案

您是否尝试在 ninja_steps 顶部添加包含?类似的东西

Did you try adding an include at the top of the ninja_steps? Something like

require File.expand_path(File.dirname(__FILE__) + "/../../src/ninja")

应该可以解决问题.否则，黄瓜不知道忍者是什么.:)

should do the trick. Otherwise, cucumber has no idea what a Ninja is. :)
