Question

我想知道是否有人可以帮助澄清要求和要求亲属之间的差异，并帮助解释这里的问题。我的文件结构是

spec/
  lion_spec.rb
  panda_spec.rb
lib/
  lion.rb
  panda.rb
  animal.rb

为了保持代码干燥，我创建了一个Animal类。我的问题是，因为这样做，我得到一个rspec错误：

uninitialized constant Animal (NameError)

我知道这通常意味着我没有正确地要求或创建课程，但我似乎无法找到这一点，现在我对这些要求感到困惑！

lion_spec

require 'animal'
require 'lion'

describe Lion do 
    it "should like wildebeests" do 
        expect(Lion.new.likes?(:wildebeests)).to eq(true)
    end

    it "should like zebras" do
    expect(Lion.new.likes?(:zebras)).to eq(true) 
    end

    it "should not like salad" do 
        expect(Lion.new.likes?(:salad)).to eq(false)
    end
end

panda_spec

require 'animal'
require 'panda'

describe Panda do 

    it 'should like bamboo' do 
        expect(Panda.new.likes?(:bamboo)).to eq(true)   
    end

    it 'should like bamboo as a string' do 
        expect(Panda.new.likes?("bamboo")).to eq(true)
    end

    it 'should not like grasshoppers' do 
        expect(Panda.new.likes?("grasshoppers")).to eq(false)
    end
end

lion.rb

require 'animal'

class Lion < Animal

    def acceptable_food
        [:wildebeests, :zebras]
    end
end

panda.rb

require 'animal'

class Panda < Animal

    def acceptable_food
        [:bamboo]
    end
end

animal.rb

require 'animal'

class Panda < Animal

    def acceptable_food
        [:bamboo]
    end
end

测试覆盖率很好我修改为以下内容：

**lion_spec**
require 'animal'
require 'lion'


describe Lion do 
    it "should like wildebeests" do 
        expect(Lion.new.likes?(:wildebeests)).to eq(true)
    end

    it "should like zebras" do
    expect(Lion.new.likes?(:zebras)).to eq(true) 
    end

    it "should not like salad" do 
        expect(Lion.new.likes?(:salad)).to eq(false)
    end
end

panda_spec 要求动物＆＃39; 要求＆＃p; panda＆＃39;

describe Panda do 

    it 'should like bamboo' do 
        expect(Panda.new.likes?(:bamboo)).to eq(true)   
    end

    it 'should like bamboo as a string' do 
        expect(Panda.new.likes?("bamboo")).to eq(true)
    end

    it 'should not like grasshoppers' do 
        expect(Panda.new.likes?("grasshoppers")).to eq(false)
    end
end 

**lion.rb**
require 'animal'


class Lion < Animal

    def acceptable_food
        [:wildebeests, :zebras]
    end
end

**panda.rb**
require 'animal'

class Panda < Animal

    def acceptable_food
        [:bamboo]
    end
end

**animal.rb**
class Animal
        def likes?(food)
        acceptable_food.include?(food.to_sym)
    end
end

要求ruby中的文件和错误
