How to test async function with Sinon JS?

问题 Below is a minimal example of what I want to achieve: I want to test fn3() being called if the async function fn2() resolved (when calling fn1 ). But I somehow failed to do that with sinon 's stub syntax. I would like to know what I misunderstood. // System Under Test export function fn1() { fn2().then(() => { fn3(); }); } export async function fn2() { return new Promise((resolve, reject) => { // expensive work resolve(); }); } export function fn3() { console.log("fn3"); } // Test import * as

Memory leak when calling too many promises in Nodejs/Request/MongoDB

可紊 提交于 2021-02-11 17:01:54
问题 When I tried to call up to 200,000 POST requests in NodeJS, it display some errors like heap memory leak. In each POST request, I want to insert the resolved data into localhost mongo DB. It's ok to make 2000 requests at one time but it's really difficult to deal with 200,000 requests. I got stuck in this problem and don't know exactly to resolve it. I really need your help or any suggestions. Thank you in advance for your help. const mongoose = require('mongoose'); const request = require(

Proxying file upload with node/express.js and node request results in corrupt files with almost dobble the file size
