This document explains:

* why MediaWiki needs even better unit testing, * what we're doing now * and what we need to do next.

This is also a request for comments & commitments to make our testing environment better. Suggestions:

* try to write more testable code, and start considering writing tests alongside it * comment on Chad's RFC to help us get out of global hell: http://www.mediawiki.org/wiki/Requests_for_comment/Configuration_database * work on better code coverage and code change statistics

Please read and comment.

I wrote it with material and help from RobLa, Chad, Krinkle, and Hashar -- thanks.
