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). function setOperatingSystemAbstractionVariables() { case "$OSTYPE" in darwin*) if [ "$(which gtimeout)" == "" ]; then echo "Please install coreutils (brew install coreutils)" exit 1 fi MKTEMP=gmktemp TIMEOUT=gtimeout DOCKER_OPTIONS="-e no_proxy=localhost " ;; linux*) MKTEMP=mktemp TIMEOUT=timeout DOCKER_OPTIONS=" " ;; *) echo "Operating system ($OSTYPE) not supported" exit 1 ;; esac } # 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.
