Rspec：弃用警告

Question

我创建了一个跟随rspec模拟运行正常，但我执行它时收到警告。

Using `stub` from rspec-mocks' old `:should` syntax without explicitly enabling the syntax is deprecated. Use the new `:expect` syntax or explicitly enable `:should` instead. called from /file/path.rb:26:in `block (3 levels) in <top (required)>'.

这是我的单元测试。在我的单元测试中，第26行是user_health_condition.stub(:user_condition_flag) do |user_id|。每次警告我都在使用期待，为什么我收到此警告？

describe '.user_condition_flag' do
  let(:expected_result_with_diabetes) { 'Y' }
  let(:expected_result_without_diabetes) { 'N' }
  let(:user_id_1) { 38 }
  let(:user_id_2) { 39 }

  context 'with entries in table' do
    it 'returns expected results' do
      user_health_condition = double(user_health_condition)
      allow(user_health_condition).to receive(:user_condition_flag).and_return(expected_result_with_diabetes)
      user_health_condition.stub(:user_condition_flag) do |user_id|
        if user_id == :user_id_1
          'Y'
        elsif user_id == :user_id_2
          'N'
        end
      end

      expect(user_health_condition.user_condition_flag(:user_id_1)).to eq(expected_result_with_diabetes)
      expect(user_health_condition.user_condition_flag(:user_id_2)).to eq(expected_result_without_diabetes)
    end
  end
end

Answer 2

在link一度死亡的情况下，详细阐述@ Brad的具体细节答案

allow(User).to receive(:find_by).and_return(user)而不是这个：

User.stub(:find_by).and_return(user)

更换

user_health_condition.stub(:user_condition_flag) do

同

allow(user_health_condition).to receive(:user_condition_flag) do
