Velox

Velox is a tool used to measure how Kolibri responds to stress testing.

Goal

Kolibri keeps evolving at a fast pace, and we need to be able to keep assessing its ability to serve as many clients as possible on given hardware specifications.

The main goals of Velox tool are to allow us to:

• set up reproducible tests to simulate various Kolibri use-case scenarios
• measure the performance of Kolibri in those scenarios

Overview

With Velox we are able to:

• automatically obtain Kolibri channels data necessary for the performance tests
• simulate clients using Kolibri content by sending API requests via Locust load testing library
• execute fully configurable test scenarios written in Python

Velox can work with both SQLite (Kolibri default) and PostgreSQL database backends
