在node.js项目中的嘲笑测试中嘲笑（实际上，间谍）哨兵

Question

我试图在Node.js项目中与Jest嘲笑（真的是Spyon）哨兵，但它无法正常工作。

/debug-sentry路由只是抛出异常，并与之正确地将异常发送给Sentry。但是，当我尝试这样模拟时，期望... tohavebeencalded失败。我不是嘲笑这个权利吗？建议？

import * as Sentry from '@sentry/node';
...
describe('failure modes', () => {
  it('send an exception to Sentry if exception thrown', async () => {
    const mock = jest.spyOn(Sentry, 'captureException');
    const res = await request(server).get('/debug-sentry').expect('Content-Type', /text/).expect(500);
    expect(mock).toHaveBeenCalled(); // This does not succeed, not sure why...
...

正在测试的代码（我刚刚添加了/debug-sentry临时用于测试服务器的路由）

import express from 'express';
import { Express } from 'express-serve-static-core';

import { requestLogger } from '@/utils/request_logger';
import {
  initialize_exception_reporting,
  initialize_error_reporting,
  send_exception_message
  } from '@/utils/exception_reporting';

export async function createServer(): Promise<Express> {
  const server = express();

  initialize_exception_reporting(server);

  server.use(requestLogger);

  // error customization, if request is invalid
  // eslint-disable-next-line @typescript-eslint/no-explicit-any,@typescript-eslint/no-unused-vars
  server.use((err: any, req: express.Request, res: express.Response, next: express.NextFunction) => {
    res.status(err.status).json({
      error: {
        type: 'request_validation',
        message: err.message,
        errors: err.errors,
      },
    });
  });

  server.get("/debug-sentry", (req, res) => {
    throw new Error("My first Sentry error!");
  });

  initialize_error_reporting(server);

  return server;
}

和设置SENTRY的代码：

import Express from 'express';
import * as Sentry from "@sentry/node";
import * as Tracing from "@sentry/tracing";

export function initialize_exception_reporting(server: Express.Express) {
  Sentry.init({
    integrations: [],
  });
  server.use(Sentry.Handlers.requestHandler());
}

export function initialize_error_reporting(server: Express.Express) {
  server.use(Sentry.Handlers.errorHandler());
}

export function send_exception_message(message: string) {
  Sentry.captureMessage(message);
}
