我正在使用 jest 进行单元测试。但是低于错误。我尝试了一些解决方案但仍然相同。请指出我哪里错了。

失败测试/登录-test.js ● 测试套件未能运行

Cannot find module 'react-apollo/test-utils' from 'login-test.js'

  3 | import Login from '../app/components/Login';
  4 | import LoginContainer from '../app/components/container/LoginContainer';
> 5 | import { MockedProvider } from 'react-apollo/test-utils';
    | ^

您必须将导入更新为：

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

来自Apollo Client 3.0 migration doc:

react-apollo v3 is an umbrella package that re-exports the following packages:

@apollo/react-common

@apollo/react-hooks

@apollo/react-components

@apollo/react-hoc

@apollo/react-ssr

@apollo/react-testing

The react-apollo package has been deprecated, and the functionality offered by each of the above packages can now be accessed from @apollo/client directly:

@apollo/react-hooks -> now available directly from @apollo/client

@apollo/react-components -> now available from @apollo/client/react/components

@apollo/react-hoc -> now available from @apollo/client/react/hoc

@apollo/react-ssr -> now available from @apollo/client/react/ssr

@apollo/react-testing -> now available from @apollo/client/testing
