Question

这是我的班级

class Hero
  attr_reader :strength, :health, :actions

  def initialize(attr = {})
    @strength = attr.fetch(:strength, 3)
    @health = attr.fetch(:health, 10)
    @actions = attr.fetch(:actions, {})

    @dicepool = attr.fetch(:dicepool) 
  end

  def attack(monster)
    @dicepool.skill_check(strength, monster.toughness)
  end

end

这些是我的测试

require 'spec_helper'
require_relative '../../lib/hero'

describe Hero do
  let(:dicepool) {double("dicepool")}

  describe "def attributes" do
    let(:hero){Hero.new dicepool: dicepool}

    it "has default strength equal to 3" do
      expect(hero.strength).to eq(3)
    end
    it "has default health equal to 10" do
      expect(hero.health).to eq(10)
    end

    it "can be initialized with custom strength" do
      hero = Hero.new strength: 3, dicepool: dicepool
      expect(hero.strength).to eq(3)
    end

    it "can be initialized with custom health" do
      hero = Hero.new health: 8, dicepool: dicepool
      expect(hero.health).to eq(8)
    end

    describe "attack actions" do
      let(:attack_action) {double("attack_action") }
      let(:hero) {Hero.new dicepool: double("dicepool"), actions: {attack: attack_action} }

      it "has attack action"
        expect(hero.actions[:attack]).to eq(attack_action)
      end
    end  


end

我一直在

在`块（3级）中＆＃39;：未定义的局部变量或方法＆＃39;英雄＆＃39;对于 RSpec :: ExampleGroups :: Hero :: DefAttributes :: AttackActions：Class（NameError）

我不知道为什么。这是我写Rspec测试的第一天，所以请你好...

Answer 1

您上次测试时输入错误，忘记了单词do：

  it "has attack action" do
    expect(hero.actions[:attack]).to eq(attack_action)
  end

一旦添加，一切都会过去。

Answer 2

您没有将阻止传递给it方法（最后您遗漏了do和end）。

 it "has attack action"
                        ^^^

正确的代码应如下所示：

describe Hero do
  let(:dicepool) {double("dicepool")}

  describe "def attributes" do
    let(:hero){Hero.new dicepool: dicepool}

    it "has default strength equal to 3" do
      expect(hero.strength).to eq(3)
    end
    it "has default health equal to 10" do
      expect(hero.health).to eq(10)
    end

    it "can be initialized with custom strength" do
      hero = Hero.new strength: 3, dicepool: dicepool
      expect(hero.strength).to eq(3)
    end

    it "can be initialized with custom health" do
      hero = Hero.new health: 8, dicepool: dicepool
      expect(hero.health).to eq(8)
    end

    describe "attack actions" do
      let(:attack_action) {double("attack_action") }
      let(:hero) {Hero.new dicepool: double("dicepool"), actions: {attack: attack_action} }

      it "has attack action" do
        expect(hero.actions[:attack]).to eq(attack_action)
      end
    end
  end
end

Rspec测试中未定义的局部变量或方法？
