Project :

Adding Custom features while upgrading and updating Quiz extension for Wikimedia Foundation

Introduction :

Quiz extension is currently used on several WMF projects, such as Wikiversity but had lot of bugs and limited features for users.By working on the project we have updated and upgraded MediaWiki Quiz extension while removing legacy code and adding new features to the extension.

Benefits of this project include stability and functionality to the extension and comprehensive features for users of various Wikis.Various custom features suggested by community were also added.

Initially one of the features that were supposed to be added was Data storage for quiz scores but it was declined for this project as decided with mentors and community.

The work can be divided into 4 major parts:

  • Importing and solving bugs
  • Removing legacy code and upgrading to MediaWiki standards
  • Providing Unit tests for the extension
  • Adding required features
