Hi.
I filed bug 26259, "MediaWiki bloated with test suites":
https://bugzilla.wikimedia.org/show_bug.cgi?id=26259
RobLa asked me to send an e-mail to wikitech-l about this bug. It's my view
that checking out MediaWiki from SVN should not include files that most
users do not need or want. These test suites seem to fit perfectly within
this category.
