Hi all,   is it possible to mockup the arguments (tctx, root, service, proplist) for the service callback without using of NCS daemon? The approch should be to validate the output based on the input for simple unit testing with pyTest and speed up the development to avoid package reload after every code change. For example: Inside cb_create does exist a function to calculate broadcast ip address based on passed ip address. I want to validate the calculated ip address.   import ncs from ncs.application import Service # ------------------------ # SERVICE CALLBACK EXAMPLE # ------------------------ class ServiceCallbacks(Service): # The create() callback is invoked inside NCS FASTMAP and # must always exist. @Service.create def cb_create(self, tctx, root, service, proplist): self.log.info('Service create(service=', service._path, ')')  I am aware of it, that the tests need further stages inside ncs to validate the service.   Thanks. ...

Hi all, I tried to validate my yang model of my ncs service by pyang.   $ pyang -p /var/opt/ncs/packages/cisco-iosxr/src/yang testservice.yang I got following error message: testservice/src/yang/testservice.yang:13: warning: imported module ietf-inet-types not used testservice/src/yang/testservice.yang:83: error: tailf-ned-cisco-ios-xr:interface in the path for TenGigE at testservice/src/yang/testservice.yang:79 is not found for following yang model: module testservice{ namespace "http://example.com/testservice"; prefix testservice; import ietf-inet-types { prefix inet; } import tailf-common { prefix tailf; } import tailf-ncs { prefix ncs; } import tailf-ned-cisco-ios-xr { prefix cisco-ios-xr; } [..] list devices { key device; leaf device { type leafref { path "/ncs:devices/ncs:device/ncs:name"; } } leaf-list TenGigE { type leafref { path "deref(../device)/../ncs:config/cisco-ios-xr:interface/cisco-ios-xr:TenGigE/cisco-ios-xr:id"; } } } } I cannot understand, why pyang throw an error for testservice/src/yang/testservice.yang:83.

If I try to validate with pyang my YANG-model with imported submodules, I need to specify the path to the external submodules. For the built-in yang-models, like ietf-inet-types, I don't need to specify the path. But the man-page of pyang describes following: See http://www.yang-central.org/twiki/pub/Main/YangTools/pyang.1.html The following directories are always added to the search path: current directory $YANG_MODPATH $HOME/yang/modules $YANG_INSTALL/yang/modules OR if $YANG_INSTALL is unset <the default installation directory>/yang/modules (on Unix systems: /usr/share/yang/modules)         module my-module { namespace "http://test.com/my-module"; prefix mymodule; import ietf-inet-types { prefix inet; } import tailf-common { prefix tailf; } import tailf-ncs { prefix ncs; } import private-module { prefix private; } //yang code ... } [root@c945565b350c yang]# pyang my-module.yang my-module.yang:15: error: module "private-module" not found in search path [root@c945565b350c yang]# So, the default path for the built-in yang modules is /ncs/src/yang/.   Does NSO exposed the path to the built-in yang modules to pyang?   Thanks     ...
