# Helper script to run the acceptance tests, which test a running Nextcloud
|
|
# instance from the point of view of a real user.
|
|
#
|
|
# The acceptance tests are run in its own Docker container; the grandparent
|
|
# directory of the acceptance tests directory (that is, the root directory of
|
|
# the Nextcloud server) is copied to the container and the acceptance tests are
|
|
# run inside it. Once the tests end the container is stopped. The acceptance
|
|
# tests also use the Selenium server to control a web browser, so the Selenium
|
|
# server is also launched before the tests start in its own Docker container (it
|
|
# will be stopped automatically too once the tests end).
|
|
#
|
|
# To perform its job, the script requires the "docker" command to be available.
|
|
#
|
|
# The Docker Command Line Interface (the "docker" command) requires special
|
|
# permissions to talk to the Docker daemon, and those permissions are typically
|
|
# available only to the root user. Please see the Docker documentation to find
|
|
# out how to give access to a regular user to the Docker daemon:
|
|
# https://docs.docker.com/engine/installation/linux/linux-postinstall/
|
|
#
|
|
# Note, however, that being able to communicate with the Docker daemon is the
|
|
# same as being able to get root privileges for the system. Therefore, you must
|
|
# give access to the Docker daemon (and thus run this script as) ONLY to trusted
|
|
# and secure users:
|
|
# https://docs.docker.com/engine/security/security/#docker-daemon-attack-surface
|
|
#
|
|
# Finally, take into account that this script will automatically remove the
|
|
# Docker containers named "selenium-nextcloud-local-test-acceptance" and
|
|
# "nextcloud-local-test-acceptance", even if the script did not create them
|
|
# (probably you will not have containers nor images with those names, but just
|
|
# in case).
|
|
|
|
# Sets the variables that abstract the differences in command names and options
|
|
# between operating systems.
|
|
#

|
# Switches between timeout on GNU/Linux and gtimeout on macOS (same for mktemp
|
|
# and gmktemp).

# Launches the Selenium server in a Docker container.
|

#
|
|
# The acceptance tests use Firefox by default but, unfortunately, Firefox >= 48
|
|
# does not provide yet the same level of support as earlier versions for certain
|
|
# features related to automated testing. Therefore, the Docker image used is not
|
|
# the latest one, but an older version known to work.
|
|
#
|
|
# The acceptance tests expect the Selenium server to be accessible at
|
|
# "127.0.0.1:4444"; as the Selenium server container and the container in which
|
|
# the acceptance tests are run share the same network nothing else needs to be
|
|
# done for the acceptance tests to access the Selenium server and for the
|
|
# Selenium server to access the Nextcloud server. However, in order to ensure
|
|
# from this script that the Selenium server was started the 4444 port of its
|
|
# container is mapped to the 4444 port of the host.
|
|
#
|
|
# Besides the Selenium server, the Docker image also provides a VNC server, so
|
|
# the 5900 port of the container is also mapped to the 5900 port of the host.
|
|
#
|
|
# The Docker container started here will be automatically stopped when the
|
|
# script exits (see cleanUp). If the Selenium server can not be started then the
|
|
# script will be exited immediately with an error state; the most common cause
|
|
# for the Selenium server to fail to start is that another server is already
|
|
# using the mapped ports in the host.
|
|
#
|
|
# As the web browser is run inside the Docker container it is not visible by
|
|
# default. However, it can be viewed using VNC (for example,
|
|
# "vncviewer 127.0.0.1:5900"); when asked for the password use "secret".
