From cfff69a3a181f2092bc4a085ca677b1b5735bda7 Mon Sep 17 00:00:00 2001 From: Siri Hansen Date: Mon, 7 May 2012 12:21:02 +0200 Subject: [common_test] Add netconf client, ct_netconfc The netconf client supports basic netconf functionality over SSH. In order to allow testing of both success and failure cases, it is intentionally written to allow non-standard behavior. In order for the netconf client to use the generic connection mechanism in common_test, ct_gen_conn has been updated to be more flexible: Added options: {reconnect,bool()} {forward_messages,bool()} {use_existing_connection,bool()} Allow handle_msg to return {reply,Reply,State} | {noreply,State} | {stop,Reply,State} If forward_messages==true, the ct_gen_conn callback must also implement: handle_msgs(Msg,State) -> {noreply,State} | {stop,State} --- lib/.gitignore | 1 + lib/common_test/doc/src/Makefile | 7 +- lib/common_test/doc/src/ref_man.xml | 3 +- lib/common_test/src/Makefile | 8 +- lib/common_test/src/common_test.app.src | 3 + lib/common_test/src/ct_conn_log_h.erl | 230 +++ lib/common_test/src/ct_gen_conn.erl | 246 ++- lib/common_test/src/ct_netconfc.erl | 1828 +++++++++++++++++++++++ lib/common_test/src/ct_netconfc.hrl | 58 + lib/common_test/src/ct_util.hrl | 3 + lib/common_test/src/cth_conn_log.erl | 124 ++ lib/common_test/test/Makefile | 5 +- lib/common_test/test/common_test.spec | 3 +- lib/common_test/test/ct_netconfc.cfg | 6 + lib/common_test/test/ct_netconfc_SUITE.erl | 1144 ++++++++++++++ lib/common_test/test/ct_test_netconf_server.erl | 506 +++++++ 16 files changed, 4098 insertions(+), 77 deletions(-) create mode 100644 lib/common_test/src/ct_conn_log_h.erl create mode 100644 lib/common_test/src/ct_netconfc.erl create mode 100644 lib/common_test/src/ct_netconfc.hrl create mode 100644 lib/common_test/src/cth_conn_log.erl create mode 100644 lib/common_test/test/ct_netconfc.cfg create mode 100644 lib/common_test/test/ct_netconfc_SUITE.erl create mode 100644 lib/common_test/test/ct_test_netconf_server.erl (limited to 'lib') diff --git a/lib/.gitignore b/lib/.gitignore index 56b1ed2b84..4125111ebd 100644 --- a/lib/.gitignore +++ b/lib/.gitignore @@ -7,6 +7,7 @@ /common_test/doc/src/ct_rpc.xml /common_test/doc/src/ct_snmp.xml /common_test/doc/src/ct_ssh.xml +/common_test/doc/src/ct_netconfc.xml /common_test/doc/src/ct_telnet.xml /common_test/doc/src/unix_telnet.xml diff --git a/lib/common_test/doc/src/Makefile b/lib/common_test/doc/src/Makefile index 2ec6952710..99161ce68a 100644 --- a/lib/common_test/doc/src/Makefile +++ b/lib/common_test/doc/src/Makefile @@ -1,7 +1,7 @@ # # %CopyrightBegin% # -# Copyright Ericsson AB 2003-2011.

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}.

Stream:

An optional parameter that indicates which stream of events +%% is of interest. If not present, events in the default NETCONF +%% stream will be sent.
+%% +%%
Filter:
+%%
An optional parameter that indicates which subset of all +%% possible events is of interest.

StartTime:
+%%
An optional parameter used to trigger the replay feature and +%% indicate that the replay should start at the time specified.

+%% +%%
StopTime:
+%%
An optional parameter used with the optional replay feature +%% to indicate the newest notifications of interest.
