如何使用Rspec测试调用find_or_initialize_by的初始化方法？

require 'rspec'
require 'path_to_your_model_file'

RSpec.describe YourModel do
  describe '#your_method' do
    context 'when the record exists' do
      it 'should not initialize a new record' do
        # 创建一个已存在的记录
        existing_record = YourModel.create(name: 'example')

        # 调用find_or_initialize_by方法
        result = YourModel.find_or_initialize_by(name: 'example')

        # 断言结果是否符合预期
        expect(result).to eq(existing_record)
      end
    end

    context 'when the record does not exist' do
      it 'should initialize a new record' do
        # 调用find_or_initialize_by方法
        result = YourModel.find_or_initialize_by(name: 'non_existing')

        # 断言结果是否为新创建的记录
        expect(result).to be_new_record
        expect(result.name).to eq('non_existing')
      end
    end
  end
end
