用jest对js脚本进行单元测试:我可以模拟es6类吗

当我从模块导入类时

const { OAuth2Client } = require('google-auth-library');

我怎么能嘲笑它呢?

jest.mock("google-auth-library");  // not mocking directly OAuth2Client

jest.mock("google-auth-library", OAuth2Client ) // is incorrect

如果我添加了在线实现,我就没有类名

jest.mock("google-auth-library", () => {
   return jest.fn().mockImplementation(() => {
      return {
        setCredentials: setCredentialsMock,
        getAccessToken: getAccessTokenMock
      }
   })
});

所以我不能调用构造函数:

const oAuth2Client = new OAuth2Client({...});

欢迎反馈

这里是与我的问题相关的google auth库nodejs中最重要的代码

google auth库nodejs模块

======================================= /src/auth/index.ts文件 … 从“./auth/oauth2client”导出{..,oauth2client,…}; … const auth=new googleauth(); 导出{auth,googleauth};

    =======================================
    /src/auth/oauth2client.js

    import {AuthClient} from './authclient';
    ...
    export class OAuth2Client extends AuthClient {
      ....
      constructor(clientId?: string, clientSecret?: string, redirectUri?: string);
      constructor(
         ...
        super();
        ...
        this._clientId = opts.clientId;
        this._clientSecret = opts.clientSecret;
        this.redirectUri = opts.redirectUri;
        ...
      }
      ...
      getAccessToken(): Promise<GetAccessTokenResponse>;
      ...
    }

======================================= /src/auth/authclient.ts文件

    import {Credentials} from './credentials';
    ...
    export abstract class AuthClient extends EventEmitter {
       ...
      setCredentials(credentials: Credentials) {
        this.credentials = credentials;
      }
    }

======================================= /src/auth/credentials.js文件

    export interface Credentials {
      refresh_token?: string|null;
      expiry_date?: number|null;
      access_token?: string|null;
      token_type?: string|null;
      id_token?: string|null;
    }
