Kamailio configuration tests
----------------------------

Requiriments:
-------------
 - A working NGCP
 - sip-tester. sipp with ssl enabled ( needed for auth ).
   We provide a version backported to wheezy
 See debian/control for the actual list of dependences


Usage:
------
  # cd /usr/share/kamailio-config-tests

  We support groups of scenarios. Each group can have different configs, see
  $BASE_DIR/$GROUP/config.yml. The default GROUP is 'scenarios'. Set GROUP to
  scenarios_XXX in order to run/test that group.

  If you are using the git version and not in /usr/share/kamailio-config-tests
  you need to set BASE_DIR environment variable accordingly:
  # export BASE_DIR=`pwd`
  This is not needed if you are using the Debian packaged version.

  PROFILE: "CE" the default
           "PRO"
  #bash ./run_tests.sh [-p PROFILE ] [-K] [-c] [-r]

  This will create:
    - $BASE_DIR/log
      with a directory per test with:
      - kamailio.log
      - kamailio-lb.log
      - sems.log
      - sems-pbx.log
      - XXXX.json  (parsed messages)
      - a pcap file for each interface (if -K option is used)
      - cdr.txt (if -c option is used)
      - sipp error logs (if any)

  #bash ./get_results.sh [-p PROFILE ] [-g] [-c] [-r]

  This will create:
    - $BASE_DIR/result
      with a directory per test with:
      - a tap file with the test results
      - a png file containing the routes flow (if -g option is used)

  If you want to run tests that belongs to a different scenarios set, use the
  -x option followed by the scenario's name:
    #bash ./run_tests.sh [-p PROFILE ] [-K] [-c] [-r] -x scenarios_lnp
    #bash ./get_results.sh [-p PROFILE ] [-g] [-c] [-r] -x scenarios_lnp

  If you want to run test manually just exec this onces:
    #./bin/config_debug.pl on
    #ngcpcfg apply 'cfgtest'
  and run the check that you want:
    #PERL5LIB="$$(pwd)/lib" ./bin/check.sh <checkname>
  this will run the test and the result taps
  or run all the tests as many times you want with:
    #./bin/bench.sh $NUM

If you want to test just a set of scenarios, set the SCENARIOS
environment var.

#bash SCENARIOS="invite invite_callforward" ./run_tests.sh -C
#bash SCENARIOS="invite invite_callforward" ./get_results.sh


Development:
------------

Every test has to be located at the scenarios directory. It must include:

 - scenario.yml
 - XXXX_test.yml.tt2
   XXXX indicates the number of kamailio parsed msg XXXX.json to test
 - sipp_scenarioXX.xml

And can optionally include:
 - sipp_scenario_responderXX.xml
 - cdr_test.yml.tt2
 - prefs.json
 - callforward.yml
 - speeddial.yml
 - peer.yml
 - trusted.yml


Test file syntax (XXXX_test.yml.tt2 files):
-------------------------------------------

The test file is divided in tree different parts:
 - flow:
  Array of routes with a possible list of pseudo-variables values to test.
  If the value is a string it will be treated as a regular expression rule[0].

  Example:
  flow:
    - start|MAIN:
        $avp(val): [1, "test"]
    - start|ROUTE_NET_INFO:
        $avp(val): [2,1]
    - end|ROUTE_NET_INFO:
        $avp(val): None
    - start|ROUTE_PRX_REQUEST:
        $xavp(caller_peer_prefs[0]=>concurrent_max): '\d+'
    - start|ROUTE_INVITE:
        $xavp(caller_peer_prefs[0]=>concurrent_max[*]): [1]
    - start|ROUTE_LOAD_CALLEE_DOMAIN_PREF:
    - start|ROUTE_CLEAR_CALLEE_DOMAIN_PREF:
    - end|ROUTE_CLEAR_CALLEE_DOMAIN_PREF:
    - end|ROUTE_LOAD_CALLEE_DOMAIN_PREF:
    - start|ROUTE_FIND_CALLER:
    - start|ROUTE_AUTH:
    - exit|ROUTE_AUTH:
        $fU: testuser

 - sip_in:
  Array of regular expresion rules[0] to match in the sip messsage. If the rule
  starts with '_:NOT:_' it will fail if the rule matches.

  Example:
  sip_in:
    - '^INVITE'
    - 'Contact: sip:testuser1002@'
    - 'CSeq: 2 INVITE'
    - 'Max-Forwards: 16'
    - 'Content-Type: application/sdp'
    - 'Proxy-Authorization: Digest username="testuser1002"'
    - '_:NOT:_Contact: <sip:testuser1003@127.126.0.1:6666;ob>;expires=\d+',

 - sip_out:
  Array of lists of regular expression rules[0] to match the array of sip messages
  send out. If the rule starts with '_:NOT:_' it will fail if the rule matches.

  Example:
  sip_out:
  - [
      '^SIP/2.0 100 Trying',
      'Content-Length: 0'
    ]
  - [
      '^SIP/2.0 403 Unauthorized IP detected',
      'Content-Length: 0',
      'P-NGCP-Authorization: testuser1003@',
      'P-NGCP-Authorized: 1'
    ]

Cdr test file syntax (cdr_test.yml.tt2):
----------------------------------------

The test file contains only one part:
 - cdr:
  Dictionary of cdr fields that should be contained in the exported CDR. The
  value will be treated as a regular expression rule[0]. If the value
  starts with '_:NOT:_' it will fail if the rule matches.

  Example:
  cdr:
    - call_id: 'abcdefg@1.1.1.1'
      source_domain: 'spce.test'
      destination_user: '*55*1420'
      call_type: 'call'
      call_status: 'ok'
      call_code: 200
    - destination_user: 'testuser1004'
      destination_user_in: 'testuser1004'
      duration: 0
      call_type: '_:NOT:_call'
      call_status: 'other'
      call_code: '403'

scenario.yml file syntax:
-------------------------

  This file is divided in two sections: subscribers and scenarios. In subscribers
  we put the info and alias numbers. In scenarios we put the info needed to run the
  sipp scenarios.

  The check.sh script will start all the responders in the background in order and then
  any sipp_scenarioXX.xml one by one.

  If the responder has register: yes a sipp_scenario_responderXX_reg.xml will be created
  and run it before the correspondent responder.

  If active: no then no sipp_scenario_responderXX.xml exists for that responder. It's just
  info of the callee.

  If foreign: yes then sipp_scenario_responderXX.xml will be run with 5060 port.

  If password_wrong: yes then the caller is going to use 'wrongpass' as password.

  Example:

  test_uuid: lock_ported
  domains:
    'spce.test':
      reseller_id: 1
  customers:
    'customer.test':
      contacts:
