您必须将您的导入更新为：

import { MockedProvider } from '@apollo/client/testing';

来自阿波罗客户端3.0迁移文档

react-apollo v3是一个伞式包，可将下列软件包再导出：

• @apollo/react-common
• @apollo/react-hooks
• @apollo/react-components
• @apollo/react-hoc
• @apollo/react-ssr
• @apollo/react-testing

已不再推荐react-apollo包，现在可以从@apollo/client直接访问上述每个包提供的功能：

• @apollo/react-hooks ->现在可以直接从@apollo/client获得
• @apollo/react-components ->现在可从@apollo/client/react/components获得
• @apollo/react-hoc ->现在可从@apollo/client/react/hoc获得
• @apollo/react-ssr ->现在可从@apollo/client/react/ssr获得
• @apollo/react-testing ->现在可从@apollo/client/testing获得
