Description

Let's use the TITAN SGsAP encoder to implement integration tests against a [future] SGs interface of OsmoMSC.

This includes our usual stack of something like a SGsAP_CodecPort, SGsAP_Emulation,... as well as the individual test cases.

The tests become part of MSC_Tests.ttcn, and can hence interact on AoIP, GSUP, SGs, VTY, CTRL, etc. with the IUT (OsmoMSC).

Tests should include tests for successful procedures as well as common error paths/cases.

Let's use the checklist here to collect what to test.

#3 Updated by laforge 2 months ago

I've started to create a quite extensive list of send and receive teplates for SGsAP, see https://gerrit.osmocom.org/#/c/osmo-ttcn3-hacks/+/11305/

Those will be the basis for the actual tests, together with the SGsAP_CodecPort.ttcn (https://gerrit.osmocom.org/#/c/osmo-ttcn3-hacks/+/11306/) and upcoming SGsAP_Emulation.ttcn modules.

First couple of test cases have been implemented. Now it's up for OsmoMSC to catch up in terms of an actual implementation that can be tested.
