My naive implementation of ab in node.js
This is a simple node script for stress testing an API. It will hammer the API on a single URL x batches of x parallel requests.
A batch consists of x number of parallel requests. When all parallel requests are finished (successful or not) then the batch is finished.
Parallel requests are done by creating a Promise for each request. And then use await Promise.allSettled to fire all the requests at once and wait for all to finish.
node test.mjs [url] [num of batches] [num of parallel request]
# e.g.
node test.mjs 'http://localhost:3001/campaign-banners?locale=ja' 20 100
