如何告诉database_cleaner不要在一组特定的rspec测试中间运行

RSpec.configure do |config|
  config.before(:suite) do
    DatabaseCleaner.strategy = :transaction
    DatabaseCleaner.clean_with(:truncation)
  end

  config.before(:each) do
    DatabaseCleaner.start
  end

  config.after(:each) do
    DatabaseCleaner.clean
  end
end

RSpec.describe "MyApp", skip_cleaner: true do
  # 这组测试将跳过数据库清理
end

RSpec.configure do |config|
  # ...

  config.before(:each) do |example|
    unless example.metadata[:skip_cleaner]
      DatabaseCleaner.start
    end
  end

  config.after(:each) do |example|
    unless example.metadata[:skip_cleaner]
      DatabaseCleaner.clean
    end
  end
end
