Continuous integration/Jenkins

Jenkins is a Java tool used to handle recurring tasks such as running tests or building packages. The Wikimedia foundation install is available at https://integration.mediawiki.org/ci/

The tool is permanently connected to our review tool (Gerrit) and can be made to react on changes submitted to Gerrit. A typical example, is running MediaWiki unit tests whenever a change is submitted to the mediawiki/core git repository.

Jobs configuration is made available publicly in the integration/jenkins git repository.

MediaWiki core
Change sent to mediawiki/core trigger the MediaWiki-GIT-Fetching job. It is responsible for fetching the latest master version and apply the change set. It then triggers a hierarchy of tests, whenever a test fail, the build will be considered as failing and a notification is sent to Gerrit for the change author to be notified.


 * 1) MediaWiki-Universal-Linter : does a php lint on all modified files.
 * 2) MediaWiki-Tests-* : tests running one of the PHPUnit groups. All those tests are run even if one of them fail.
 * 3) When those tests have run successfully, a copy of the installation is made available publicly and a script send a test request to Testswarm.

Android applications
The WMF produce two androids application (WikipediaMobile and WiktionaryMobile), hosted on github, Jenkins is notified whenever a change is merged in github. It will then fetch the master branch and build the application.

Status
