# Tests GUPnPDLNADiscoverer by running tools/gupnp-dlna-info on the given list
# of media and comparing that against expected DLNA profile name and MIME type.
#
# Usage:
#   test-discoverer.sh <file_list> <media_dir> <extra_args ...>
#
# <file_list> is a CSV file in the format:
#   path_name,profile_name,mime_type
#
# Path names in the list are relative to <media_dir>
#
# <extra_args> are passed on to gupnp-dlna-info
#
# The first two parameters can be passed as the FILE_LIST and MEDIA_DIR
# environment variable as well (but you must either pass both as env vars or
# both on the command line).
#

# This test is trialled when executing 'make check'. In that case the
# $MEDIA_DIR is ./tests/media (where . is gupnp-dlna's source code
# directory).
# You can get the default test media collection using the following command:
#   git clone git://git.gnome.org/gupnp-dlna-media tests/media
