# Yang leafref + state tests
# The difficulty here is a "leafref" in state data that references config-data.
# Problem being that config-data from running needs to be mergedwith state data and filtered/cropped
# correctly
#
# The YANG has two parts, one config part (sender-config) and one state part (sender-state)
# The leafref in the sender-state part references a leaf in the sender-config part
# Netconf tests are made to get state, state+config, using content attribute config/nonconfig/all
# with different paths.
# Using the -sS <file> state capability of the main example, that is why CLICON_BACKEND_DIR is
# /usr/local/lib/$APPNAME/backend so that the main backend plugins is included.
# These tests require VALIDATE_STATE_XML to be set
# Magic line must be first in script (see README.md)
