Bypass UE log analysis when testing sidelink, as it fails due to the absence
of expected information and patterns (not present in sidelink communication).
Instead, a custom command is used to verify the success of sidelink tests by
checking for the presence of "PSBCH RX:OK" in the log of the second UE.
Don't break after first occurence of status template (interval "0.0- 1.0 sec").
With this modification we get final result, which is at the last line of log
(for interval "0.0-30.2 sec").
Remove code related to "rfsim4g_enb_fembms" testcase from Iperf_Module() -
replaced by Iperf2_Unidir(). Use copyin() for both remote and local
commands - no need to check if running on localhost anymore.
Create directory for log collection on executor node -
used for log collection in pipelines running on localhost.
Copy the iperf3 report to the executor machine for log collection.
The report needs to be copied to two different directories to ensure
proper log collection across all pipelines. Using absolute paths
ensures compatibility with both remote and local commands.
In some testcases, especially when iperf test duration is short (10s),
client does not report on time and report collection is interrupted.
This commit increase timeout for iperf/iperf3 commands.
In some pipelines, it happens that iperf3 is hanging on 100% CPU load.
In these cases, a simple TERM signal does not seem to be enough to kill
it; KILL is necessary.
While e.g., RemoteCmd's driver paramiko has a timeout command, the
documentation [1] is not really clear how it is trying to stop commands.
Since it effectively does not stop, we have to assume it is only sending
TERM.
To remedy this, use the timeout command to start iperf3. We use option
-v for diagnose timeouts on stderr, and send KILL after an additional 3
seconds (-k3) if TERM does not succeed. The timeout is sent to the same
duration as the overall iperf timeout.

Simplification of the code by replacing iperf_opt by target_bitrate (returned from Iperf_ComputeModifiedBW) - no need to repeat the steps to retrieve information about requested bitrate from iperf_opt. Compute iperf bitrate performance as receiver bitrate over requested (target) bitrate.
Fix an issue with misdetection of missing report line - "result" was defined 2x in the function. With this MR, result can be only None or stores output of re.search() for matching the report line pattern, which ensure proper detection of the report line as well as presence off all required components in the report line.
Sender bitrate is not always equal to the requested bitrate (set by "-b" iperf option) in iperf3 (v3.9) UDP tests, so we have to compture bitrate performance of UDP iperf3 test as receiver over requested bitrate. Bitrate performance then express percentage of requested bitrate, which is received on the receiver side.
For iperf3 (version 3.9) UDP, sender bitrate is not always equal to requested bitrate (defined by '-b' option). We need to retrieve information about the requsted bitrate from iperf command line options specified for each UDP testcase. This parameter is then used in UDP analysis functions for proper evaluation of the test results.
- CI_OC_RAN_NAMESPACE for RAN images
- CI_OC_CORE_NAMESPACE for CN deployment
- usage of the created constants for pulling images from cluster, CN deployement, iperf/ping
- IPERF3 option created in cls_oaicitest.py
- retrieval of CN amf and traffic-server IP address from pods
- modification of gNB config file (do_SRS set, max UL MCS increased), removal of unused config file
- change of AmariUE config file to support 2x2
- modification of xml file for aw2s pipeline - iperf test added
- new xml file for cleanup (terminate AmariUE, clean test server images) created
Following changes are made:
1. Removed XMLs used in old pipeline lte-OAIEPC
2. Added TM1 and TM2 config, XML and YAML
3. Added pipeline details in TestBenches.md
4. Modification in Jenkins file for the pipeline
5. Added ping/iperf test cases in XML
6. Minor modification in cls_containerize.py and cls_oaicitest.py
