* This test suite tests OsmoBSC while emulating both multiple BTS + MS as
|
||||
* well as the MSC. See README for more details.
|
||||
*
|
||||
* There are test cases that run in so-called 'handler mode' and test cases
|
||||
* that run directly on top of the BSSAP and RSL CodecPorts. The "handler mode"
|
||||
* tests abstract the multiplexing/demultiplexing of multiple SCCP connections
|
||||
* and/or RSL channels and are hence suitable for higher-level test cases, while
|
||||
* the "raw" tests directly on top of the CodecPorts are more suitable for lower-
|
||||
* level testing.

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.

||||
