Harald Welte 6807982106 Makefile: clone dependencies into 'deps' folder We used to rely on out-of-tree git clones to be prepared by the user. This commit changes the system to make sure we clone all git repos we depend upon into the 'deps' folder, and then setup the symlinks to that folder. As a result, we should be able to support self-contained builds using the makefiles in this repo.		2017-12-12 16:30:53 +01:00

Integration Tests for OsmoBSC which we can perform from TTCN-3

= exhaustion of resources

* send many CHAN RQD (any) and count if all channels get actually allocated
** verify BTS_CTR_CHREQ_TOTAL reflects number sent on RSL
** verify how quickly they get released again
** verify that CHAN RQD with same RA + FN get only on allocation
* verify that we get IMM_ASS_REJ once channels are exhausted
** verify BTS_CTR_CHREQ_NO_CHANNEL increments accordigly
* verify for particular channel type / cause values
* verify that IMM.ASS.REJ has increasing back-off
* verify how BSC reacts to AGCH overload (DELETE IND)


= paging

* page by TMSI vs. page by IMSI
* verify if CCCH_LOAD_IND(PCH) slot count is observed
* verify paging expiration
* paging with different identity (lac/cgi/...) on A interface -> expect on right BSC(s)

= hand-over

* intra-BSC HO
* handover detect when not expected

= erroneous channel release

* no response to CHAN ACT
* CONN FAIL IND from BTS
** verify counter increment of BTS_CTR_CHAN_RF_FAIL
* no (or late?) response to RF CHAN REL
* no (or late?) response to RLL RELEASE REQ
* RLL messages on not-activated channels

= misc

* SMS-CB
* behavior in case of CHAN ACT NACK
* EST REQ for SAPI3 originating from core
* behavior of BSC in various error cases  (ERR IND)
** BTS_CTR_CHAN_RLL_ERR increment on T200_EXPIRED
* MODE MODIFY with ACK / NACK / no response

= IPA voice related

* expect IPA CRCX, send UDP flows, expect them on AoIP
* expect RTCP 
* missing RTP flow?
* missing RTCP?
* missing / drop-outs in RTP flow[s]
* no response to IPA CRCX / MDCX / DLCX

= counters

* test each and every counter in BSC, validate via CTRL interface
** RSL/OML failure: drop link, expect BTS_CTR_BTS_xxx_FAIL +1
** paging
*** send PAGING from MSC side
*** expect BSC_CTR_PAGING_ATTEMPTED increase by one
*** expect BSC_CTR_PAGING_EXPIRED on T3113 expiration
** BTS_CTR_CODEC_* on CHAN_ACT_ACK
* new counter ideas
** number of SCCP CR timeouts
** number of incoming RESET from MSC

= VTY based/corresponding tests

* changes in BCCH FILLING
* changes in SACCH FILLING
