Subject: Add structure test for ContentHandler::makeEmptyContent()
X-Git-Tag: 1.31.0-rc.0~5640^2
X-Git-Url: https://git.cyclocoop.org/%7B%24admin_url%7Dcompta/operations/supprimer.php?a=commitdiff_plain;h=f86d2a63e4ac89dfc3438b018da853247fdadaee;p=lhc%2Fweb%2Fwiklou.git

Add structure test for ContentHandler::makeEmptyContent()

This adds a structure test that verifies all registered ContentHandlers
will return a valid content object (as determined by
Content::isValid()), when makeEmptyContent() is called. Additionally, if
the handler extends TextContentHandler, it will verify it is an instance
of TextContentHandler::getContentClass().

This is a structure test so it is run for content handlers created by
extensions as well.
