Selenium tests

Prerequisites

• Chrome
• ChromeDriver
• Node.js

If using MediaWiki-Vagrant:

cd mediawiki/vagrant
vagrant up

Installation

cd mediawiki
npm install

Usage

npm run selenium

By default, Chrome will run in headless mode. If you want to see Chrome, set DISPLAY environment variable to any value:

DISPLAY=1 npm run selenium

To run only one test (for example specs/page.js), you first need to start Chromedriver:

chromedriver --url-base=wd/hub --port=4444

Then, in another terminal:

npm run selenium-test -- --spec tests/selenium/specs/page.js

You can also filter specific cases, for ones that contain the string 'preferences':

npm run selenium-test -- tests/selenium/specs/user.js --mochaOpts.grep preferences

The runner reads the configuration from wdio.conf.js. The defaults target a MediaWiki-Vagrant installation on http://127.0.0.1:8080 with a user "Admin" and password "vagrant". Those settings can be overridden using environment variables:

• MW_SERVER: to be set to the value of your $wgServer
• MW_SCRIPT_PATH: ditto with $wgScriptPath
• MEDIAWIKI_USER: username of an account that can create users on the wiki
• MEDIAWIKI_PASSWORD: password for above user

Example:

MW_SERVER=http://example.org MW_SCRIPT_PATH=/dev/w npm run selenium
