# Helper script to run the acceptance tests, which test a running Nextcloud
# instance from the point of view of a real user, configured to start the
# Nextcloud server themselves and from their grandparent directory.
#
# The acceptance tests are written in Behat so, besides running the tests, this
# script installs Behat, its dependencies, and some related packages in the
# "vendor" subdirectory of the acceptance tests. The acceptance tests expect
# that the last commit in the Git repository provides the default state of the
# Nextcloud server, so the script installs the Nextcloud server and saves a
# snapshot of the whole grandparent directory (no .gitignore file is used) in
# the Git repository. Finally, the acceptance tests also use the Selenium server
# to control a web browser, so this script waits for the Selenium server
# (which should have been started before executing this script) to be ready
# before running the tests.

# Exit immediately on errors.
set -o errexit

# Ensure working directory is script directory, as some actions (like installing
# Behat through Composer or running Behat) expect that.

# Although Behat documentation states that using the BEHAT_PARAMS environment
# variable "You can set any value for any option that is available in a
# behat.yml file" this is currently not true for the constructor parameters of
# contexts (see https://github.com/Behat/Behat/issues/983). Thus, the default
# "behat.yml" configuration file has to be adjusted to provide the appropriate
# parameters for NextcloudTestServerContext.
