Integration Tests for OsmoBSC
|
|
-----------------------------
|
|
|
|
This test suite tests OsmoBSC while emulating both multiple BTS + MS as
|
|
well as the MSC.
|
|
|
|
In terms of external entities, you will need to run
|
|
* osmo-mgw in order to properly terminate the MGCP commands by the BSC
|
|
* osmo-stp as STP between the simulated MSC and osmo-bsc
|
|
* 3x osmo-bts-omldummy as this test suite only implements RSL and no OML
|
|
|
|
The included jenkins.sh script, together with the Dockerfiles from
|
|
http://git.osmocom.org/docker-playground/ can be used to run both the
|
|
osmo-bsc-under-test as well as the extenal entities and the tester.
|
|
|

Further Test Ideas
|
|
------------------
|
|
|
|
This is a random list of things about things possible to test.
|
|
Asterisks '*' are TODO, while 'x' means already implemented.
|
|
|
|
= exhaustion of resources
|
|
|
|
x send many CHAN RQD (any) and count if all channels get actually allocated
|
|
xx 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
|
|
x verify that we get IMM_ASS_REJ once channels are exhausted
|
|
xx 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
|
|
|
|
x page by TMSI vs. page by IMSI
|
|
x verify if CCCH_LOAD_IND(PCH) slot count is observed
|
|
x verify paging expiration
|
|
x paging with different identity (lac/cgi/...) on A interface -> expect on right BSC(s)
|
|
|
|
= assignment
|
|
|
|
x CSD call
|
|
x CTM telephony
|
|
x CIC on AoIP
|
|
x missing CodecList IE
|
|
* with no CIC and no AoIP
|
|
* with IPv6 Address in AoIP
|
|
* with LCLS information
|
|
x supported/unsupported/invalid ciphers
|
|
* supported/unsupported/invalid codecs
|
|
* inconsistent channel type + codec + codec-list
|
|
* on full BTS -> fail
|
|
|
|
= hand-over
|
|
|
|
* intra-BSC HO
|
|
* handover detect when not expected
|
|
|
|
= erroneous channel release
|
|
|
|
x no response to CHAN ACT
|
|
x CONN FAIL IND from BTS
|
|
xx 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
|
|
x RLL messages on not-activated channels
|
|
|
|
= misc
|
|
|
|
* SMS-CB
|
|
x 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
|
|
* invalid message type / IE type
|
|
** verify BSSAP CONFUSION is sent in all applicable cases
|
|
|
|
= 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
|
|
xx RSL/OML failure: drop link, expect BTS_CTR_BTS_xxx_FAIL +1
|
|
xx paging
|
|
xxx send PAGING from MSC side
|
|
xxx expect BSC_CTR_PAGING_ATTEMPTED increase by one
|
|
xxx 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
|
|
|
|
= dynamic TS switching
|
|
|
|
* TBD
