The Netconf client is compliant with RFC4741 and RFC4742.

+%% +%%

For each server to test against, the following entry can be +%% added to a configuration file:

+%% +%%

`{server_id(),options()}.'

+%% +%%

The `server_id()' or an associated `target_name()' (see +%% {@link ct}) shall then be used in calls to {@link open/2}.

+%% +%%

If no configuration exists for a server, a session can still be +%% opened by calling {@link open/2} with all necessary options given +%% in the call. The first argument to {@link open/2} can then be any +%% atom.

+%% +%% == Logging == +%% +%% The netconf server uses the `error_logger' for logging of netconf +%% traffic. A special purpose error handler is implemented in +%% `ct_conn_log_h'. To use this error handler, add the `cth_conn_log' +%% hook in your test suite, e.g. +%% +%% ``` +%% suite() -> +%% [{ct_hooks, [{cth_conn_log, [{conn_mod(),hook_options()}]}]}]. +%%''' +%% +%% The `conn_mod()' is the name of the common_test module implementing +%% the connection protocol, e.g. `ct_netconfc'. +%% +%% The hook option `log_type' specifies the type of logging: +%% +%%
+%%
`raw'
+%%
The sent and received netconf data is logged to a separate +%% text file as is without any formatting. A link to the file is +%% added to the test case HTML log.
+%% +%%
`pretty'
+%%
The sent and received netconf data is logged to a separate +%% text file with XML data nicely indented. A link to the file is +%% added to the test case HTML log.
+%% +%%
`html (default)'
+%%
The sent and received netconf traffic is pretty printed +%% directly in the test case HTML log.
+%% +%%
`silent'
+%%
Netconf traffic is not logged.
+%%
+%% +%% By default, all netconf traffic is logged in one single log +%% file. However, it is possible to have different connections logged +%% in separate files. To do this, use the hook option `hosts' and +%% list the names of the servers/connections that will be used in the +%% suite. Note that the connections must be named for this to work, +%% i.e. they must be opened with {@link open/2}. +%% +%% The `hosts' option has no effect if `log_type' is set to `html' or +%% `silent'. +%% +%% The hook options can also be specified in a configuration file with +%% the configuration variable `ct_conn_log': +%% +%% ``` +%% {ct_conn_log,[{conn_mod(),hook_options()}]}. +%% ''' +%% +%% For example: +%% +%% ``` +%% {ct_conn_log,[{ct_netconfc,[{log_type,pretty}, +%% {hosts,[key_or_name()]}]}]} +%% ''' +%% +%% Note that hook options specified in a configuration file +%% will overwrite the hardcoded hook options in the test suite. +%% +%% === Logging example 1 === +%% +%% The following `ct_hooks' statement will cause pretty printing of +%% netconf traffic to separate logs for the connections named +%% `nc_server1' and `nc_server2'. Any other connections will be logged +%% to default netconf log. +%% +%% ``` +%% suite() -> +%% [{ct_hooks, [{cth_conn_log, [{ct_netconfc,[{log_type,pretty}}, +%% {hosts,[nc_server1,nc_server2]}]} +%% ]}]}]. +%%''' +%% +%% Connections must be opened like this: +%% +%% ``` +%% open(nc_server1,[...]), +%% open(nc_server2,[...]). +%% ''' +%% +%% === Logging example 2 === +%% +%% The following configuration file will cause raw logging of all +%% netconf traffic into one single text file. +%% +%% ``` +%% {ct_conn_log,[{ct_netconfc,[{log_type,raw}]}]}. +%% ''' +%% +%% The `ct_hooks' statement must look like this: +%% +%% ``` +%% suite() -> +%% [{ct_hooks, [{cth_conn_log, []}]}]. +%% ''' +%% +%% The same `ct_hooks' statement without the configuration file would +%% cause HTML logging of all netconf connections into the test case +%% HTML log. +%% +%% == Notifications == +%% +%% The netconf client is also compliant with RFC5277 NETCONF Event +%% Notifications, which defines a mechanism for an asynchronous +%% message notification delivery service for the netconf protocol. +%% +%% Specific functions to support this are {@link +%% create_subscription/6} and {@link get_event_streams/3}.
