Selenium/How-to/Run tests targeting MediaWiki-Vagrant
For this example, we will not enable any roles and we will use MediaWiki Core.
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.
- 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.
Set up MediaWiki-Vagrant
- Follow instructions at MediaWiki-Vagrant.
Boot the machine
Depending on your operating system, installing dependencies will be different.
- Install Chrome.
- Install Node.js.
- Install required npm packages.
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 (
~/.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
npm run selenium-test
halt the machine
