Rspec中嵌套字段的语法

# 假设我们有一个Person类，其中包含嵌套的Address对象
class Person
  attr_accessor :name, :age, :address

  def initialize(name, age, address)
    @name = name
    @age = age
    @address = address
  end
end

# 假设我们有一个Address类，其中包含嵌套的city字段
class Address
  attr_accessor :street, :city

  def initialize(street, city)
    @street = street
    @city = city
  end
end

# 使用Rspec进行测试
RSpec.describe Person do
  describe "nested fields" do
    let(:address) { Address.new("123 Main St", "New York") }
    let(:person) { Person.new("John Doe", 30, address) }

    it "should have the correct nested field values" do
      expect(person.name).to eq("John Doe")
      expect(person.age).to eq(30)
      expect(person.address).to eq(address)
      expect(person.address.city).to eq("New York")
    end
  end
end
