Selenium/Getting Started/Run tests targeting MediaWiki-Docker

This page describes how to run Selenium tests locally on your development install of MediaWiki. This tutorial is based on the setup from MediaWiki-Docker.

AdvantagesEdit

  • It will be fast, since the target machine is local. MediaWiki core Selenium test run takes about 4 minutes on my machine. (As of September 2019.)
  • Works without an internet connection.

DisadvantagesEdit

  • You will have to install MediaWiki, Selenium and their dependencies on your machine.
  • You will be executing over 900 JavaScript packages (as of August 2019) directly on your machine with access to all personal/work files.

PrerequisitesEdit

Go to mediawiki folderEdit

cd mediawiki

Install dependenciesEdit

npm ci

Environment variablesEdit

Ensure the following environment variables are set. Either run this manually from the terminal or, to make it easier for next time, set them from shell configuration file (~/.bash_profile, ~/.zshrc...) which means the variables are always available from any terminal session:

export MW_SERVER=http://localhost:8080
export MW_SCRIPT_PATH=/
export MEDIAWIKI_USER=Admin
export MEDIAWIKI_PASSWORD=dockerpass

Run Selenium testsEdit

npm run selenium
