Selenium/How-to/Run tests targeting MediaWiki-Vagrant

< Selenium‎ | How-to
(Redirected from Selenium/Getting Started/Run tests targeting MediaWiki-Vagrant)

For this example, we will not enable any roles and we will use MediaWiki Core.


Advantages edit

Running Selenium tests targeting MediaWiki-Vagrant machine has several 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 September 2019.)
  • After everything is set up, you do not need internet connection.
  • Debugging failed tests will be easier, since you are able to see the browser. See Selenium/How-to/Make the browser visible.
  • You are probably already familiar with MediaWiki-Vagrant and have it installed.

Disadvantages edit

  • You might not be familiar with MediaWiki-Vagrant, so you will have to learn how to install and use yet another tool.
  • You will have to install Vagrant, MediaWiki-Vagrant 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.

Set up MediaWiki-Vagrant edit

Boot the machine edit 

vagrant up

Go to mediawiki folder edit 

cd mediawiki

Install dependencies edit

Depending on your operating system, installing dependencies will be different.

Chrome edit

Node.js edit

  • Install Node.js.
  • Install required npm packages.
  Warning: Running npm ci is not safe. See How to protect yourself from npm.
npm ci

Environment variables edit

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: 

# Target MediaWiki-Vagrant
export MW_SERVER=http://localhost:8080
export MW_SCRIPT_PATH=/w
export MEDIAWIKI_USER=Admin
export MEDIAWIKI_PASSWORD=vagrant

If you prefer, you can create an .env file instead (in MediaWiki Core folder), with this contents. 

# Target MediaWiki-Vagrant
MW_SERVER=http://localhost:8080
MW_SCRIPT_PATH=/w
MEDIAWIKI_USER=Admin
MEDIAWIKI_PASSWORD=vagrant

Run Selenium tests edit 

npm run selenium-test

suspend or halt the machine edit 

vagrant suspend

or 

vagrant halt
