Subject: Extensions may add tests by directory
X-Git-Tag: 1.31.0-rc.0~13542^2
X-Git-Url: http://git.cyclocoop.org/%22%2C%20generer_url_ecrire%28?a=commitdiff_plain;h=cf4654399bd3e1c109ec8f94bfa69fc44de18054;p=lhc%2Fweb%2Fwiklou.git

Extensions may add tests by directory

The UnitTestsList hook can now be used to add entire directories of
tests, à la phpunit.xml's <directory> tag.  The test suite is built by
recursively scanning the directory for any files ending in "Test.php".

TODO:
* Update online hook documentation.
* Generate and autoload a classmap for scanned directories.
