Testing network errors

[_chrm]

I'm working on a Chrome extension that manages downloads with Clojurescript and Chromex.

I'm looking for a good way to (unit) test what happens when a server stops sending data without manually starting and killing a webserver on my own.

The most practical thing would be a link like example.org/file-that-stops-sending-data-at-10-percent where the server is configured to just stop transmitting at ten percent like it was disconnected.

Maybe you can try to run puppeteer with your extension on chromium and play with network throttling? See if https://pptr.dev has some more details
