Selenium/How-to/Run tests targeting Quibble

This page describes how to run Selenium tests locally against your own MediaWiki install.

Note that if you use MediaWiki-Vagrant, there is a dedicated page for running Selenium Node.js on MediaWiki-Vagrant.

Advantages

 * It will be fast, since the target machine is local. MediaWiki core Selenium test run takes about 2 minutes on my machine. (As of October 2019.)
 * Works without an internet connection.
 * Doesn't require installing ChromeDriver or FFmpeg (compared to bare installs).
 * Doesn't require executing npm packages directly on your machine (which is scary).

Disadvantages

 * You need to have Docker installed.

Prerequisites

 * Docker. See Docker CE for Linux, Docker for Mac, or Docker for Windows.
