This repository contains a simple tool for testing the performance of resumable upload servers using k6. It currently supports draft-ietf-httpbis-resumable-upload-03.
To use, please install k6 and clone this repository. Running the load tester is then a matter of adjusting the configuration variables in the beginning of uploads.js and then executing it using k6:
$ k6 run uploads.js
