dia_generator

generate a diagram based on input file

The purpose of this script is trying to generate a diagram for the test spec of test case.

Implementation Plan:

1. Get the info from test case

• Node list interact with SAPC (SGSN, SASN, AF, OCS, APS, EBM, EMA, BBERF, SGSN-MME, etc)
• Message type (CCR/A, RAR/A, AAR/A, SLR/A, STR/A, Login/logout, Accouting_Start/Stop, etc)

2. Display the Diagram:

• Node Name
• Message with number
• Message line with direction
• Key AVPs with message
• Close the diagram

3. Version:

• 0.1 => Get the information from the ttcn file

  • Only Node list
  • Show the digram based on the number fo nodes 2014-09-20

• 0.2 => Get the sequence number of the procedure

  • Sequence number is ready 2014-09-21

• 0.3 => Get the message type

  • Add CCR/A, RAR/A message in the diagram
  • BBERF, SGSN_MME, GGSN, AF

• 0.4 => Get the input from first parameter

  • $1

• 0.5 => Avoid node with multiple interfaces

  • awk by 2 steps

• 0.6 => Combine the message direction based on node sequence

  • done
  • optimmize

• 0.7 => Add AF support

  • message: AAR/A, STR/A, ASR/A, RAR/A Thu Oct 2 17:09:08 CEST 2014

• 0.8 => Add EMA support | Profile change by OAM | Reauthorization by ToD | test case: ./generate_diagram.sh ~/Downloads/ts_43_Gxa/ts_43_Gxa/ch_02_Gxa_Support/sch_02_03_IpCan_Session_Reauthorization_By_Oam/tc_02_03_01_IpCanSession_Update_By_Adding_Services/tc_02_03_01_IpCanSession_Update_By_Adding_Services.ttcn

• 0.8.1 => Refactor the code

  • Abstract the common part for show_message function

• 0.8.2 => Add detailed messge info in the diagram below

  • Reuse the current implementation Fri Oct 10 22:21:51 CST 2014

• 0.8.3 => Add configuration part of test case | Go through the ldif and extract the dn:CotextName=, to retrieve the resource, suject, policy and rule

• 0.9 => Add multiple sessions with same type of node

• 0.9.1 => Add usage function to improve Ease of Use | configure the corrent order in the beginning | Use node from GGSN, GGSN2

• 0.9.2 => How to control the flow by node sequence smmothly?

• 0.9.3 => How to differentiate multiple sessions in the same node?
