The acceptance tests verify that a Nextcloud server works as expected
from the point of view of an end-user. They are specified as user
stories using Behat paired with Mink, which provides web browser
automation.
Mink supports several browser emulators, but the system is set up to use
Selenium, as it is FOSS and the one that better reflects the use of a
web browser by an end-user (as, in fact, it controls real web browsers).
