ONAP Maturity Testing Notes

Historically integration team used to execute specific stability and resilience tests on target release. For frankfurt a stability test was executed. Openlab, based on Frankfurt RC0 dockers was also observed a long duration period to evaluate the overall stability. Finally the CI daily chain created at Frankfurt RC0 was also a precious indicator to estimate the solution stability.

No resilience or stress tests have been executed due to a lack of resources and late availability of the release. The testing strategy shall be amended in Guilin, several requirements have been created to improve the S3P testing domain.


ONAP stability was tested through a 72 hour test. The intent of the 72 hour stability test is not to exhaustively test all functions but to run a steady load against the system and look for issues like memory leaks that cannot be found in the short duration install and functional testing during the development cycle.

Integration Stability Testing verifies that the ONAP platform remains fully functional after running for an extended amounts of time. This is done by repeated running tests against an ONAP instance for a period of 72 hours.

**The 72 hour stability run result was PASS**

The onboard and instantiate tests ran for over 115 hours before environment issues stopped the test. There were errors due to both tooling and environment errors.

The overall memory utilization only grew about 2% on the work nodes despite the environment issues. Interestingly the kubernetes ochestration node memory grew more which could mean we are over driving the API’s in some fashion.

We did not limit other tenant activities in Windriver during this test run and we saw the impact from things like the re-installation of SB00 in the tenant and general network latency impacts that caused openstack to be slower to instantiate. For future stability runs we should go back to the process of shutting down non-critical tenants in the test environment to free up host resources for the test run (or other ways to prevent other testing from affecting the stability run).

The control loop tests were 100% successful and the cycle time for the loop was fairly consistent despite the environment issues. Future control loop stability tests should consider doing more policy edit type activites and running more control loop if host resources are available. The 10 second VES telemetry event is quite aggressive so we are sending more load into the VES collector and TCA engine during onset events than would be typical so adding additional loops should factor that in. The jenkins jobs ran fairly well although the instantiate Demo vFWCL took longer than usual and should be factored into future test planning.


The Stability Test has two main components:

  • Running “ete stability72hr” Robot suite periodically. This test suite verifies that ONAP can instantiate vDNS, vFWCL, and VVG.
  • Set up vFW Closed Loop to remain running, then check periodically that the closed loop functionality is still working.

The integration-longevity tenant in Intel/Windriver environment was used for the 72 hour tests.

The onap-ci job for “Project windriver-longevity-release-manual” was used for the deployment with the OOM set to frankfurt and Integration branches set to master. Integration master was used so we could catch the latest updates to integration scripts and vnf heat templates.

The jenkins job needs a couple of updates for each release:

  • Set the integration branch to ‘origin/master’
  • Modify the parameters to deploy.sh to specify “-i master” and “-o frankfurt” to get integration master an oom frankfurt clones onto the nfs server.

The path for robot logs on dockerdata-nfs changed in Frankfurt so the /dev-robot/ becomes /dev/robot


For Frankfurt release, the stability test has been executed on an kubernetes infrastructure based on El Alto recommendations. The kubernetes version was 1.15.3 (frankfurt 1.15.11) and the helm version was 2.14.2 (frankfurt 2.16.6). However the ONAP dockers were updated to Frankfurt RC2 candidate versions. The results are informative and can be compared with previous campaigns. The stability tests used robot container image 1.6.1-STAGING-20200519T201214Z. Robot container was patched to use GRA_API since VNF_API has been deprecated.

Shakedown consists of creating some temporary tags for stability72hrvLB, stability72hrvVG,stability72hrVFWCL to make sure each sub test ran successfully (including cleanup) in the environment before the jenkins job started with the higher level testsuite tag stability72hr that covers all three test types.

Clean out the old buid jobs using a jenkins console script (manage jenkins)

def jobName = "windriver-longevity-stability72hr"=
def job = Jenkins.instance.getItem(jobName)
job.getBuilds().each { it.delete() }
job.nextBuildNumber = 1

appc.properties updated to apply the fix for DMaaP message processing to call http://localhost:8181 for the streams update.

  • Overall results were good. All of the test failures were due to issues with the unstable environment and tooling framework.
  • JIRAs were created for readiness/liveness probe issues found while testing under the unstable environment. Patches applied to oom and testsuite during the testing helped reduce test failures due to environment and tooling framework issues.
  • The vFW Closed Loop test was very stable and self recovered from environment issues.

CI results

A daily Frankfurt CI chain has been created after RC0.

The evolution of the full healthcheck test suite can be described as follows:


Full healthcheck testsuite verifies the status of each component. It is composed of 47 tests. The success rate from the 9th to the 28th was never under 95%.

4 test categories were defined:

  • infrastructure healthcheck: test of ONAP kubernetes cluster and help chart status
  • healthcheck tests: verification of the components in the target deployment environment
  • smoke tests: basic VM tests (including onboarding/distribution/instantiation), and automated use cases (pnf-registrate, hvves, 5gbulkpm)
  • security tests

The security target (66% for Frankfurt) was reached after the RC1. A regression due to the automation of the hvves use case (triggering the exposition of a public port in HTTP) was fixed on the 28th of May.


Orange Openlab

The Orange Openlab is a community lab targeting ONAP end user. It provides an ONAP and cloud resources to discover ONAP. A Frankfurt pre-RC0 version was installed beginning of May. The usual gating testing suite was run daily in addition of the traffic generated by the lab users. The VM instantiation has been working well without any reinstallation over the 27 last days.


The resilience test executed in El Alto was not realized in Frankfurt.
