clixon/test/test_feature.sh
Olof hagsand 339b744835 * Optional yangs for testing have been removed from the Clixon repo 
* These were included for testing
  * If you want to run the Clixon test suite you need to point `YANGMODELS`, see test/README.md
  * The following configure options have been removed:
    * `configure --with-opt-yang-installdir=DIR`
    * `configure   --enable-optyangs`
  * You may need to specify standard YANGs using configure option `--with-yang-standard-dir=DIR`
* Updated yang ietf models with fetures for tet
* Added option `CLICON_YANG_AUGMENT_ACCEPT_BROKEN` to accept broken yangmodels.
  * This is a debug option for CI testcases where standard YANG models are broken

# Yang features. if-feature.
# The test has a example module with FEATURES A and B, where A is enabled and
# B is disabled.
# It also uses an ietf-router module where (only) router-id is enabled
# Also check modules-state (RFC7895) announces the enabled features.
#
# From RFC7950:
# 7.20.1 Schema nodes tagged with an "if-feature" statement are _ignored_ by
# the server unless the server supports the given feature expression.
# 8.1: There MUST be no nodes tagged with "if-feature" present if the
# "if-feature" expression evaluates to "false" in the server.
# - Should the server just "ignore" these nodes or actively reject them?
#
# Clixon has a strict implementation of the features so that setting
# data with disabled features is same as if they are not present in the Yang.
# Which means no cli syntax or edit operations were syntactically allowed
# (and therefore invalid).
# Magic line must be first in script (see README.md)
