This is also happening on DokuWiki. It looks like while the (old) Trusty one was working, the Xenial default upgrade makes this issue arise:

For anyone arriving here from Google - you are probably using phpunit in your scripts.

Change it to ./vendor/bin/phpunit to use the version that Composer installs and you should be all set.
