1.1.5. Release Data¶

1.1.6. Release Deliverables¶

1.1.7. Reason for Fraser¶

• Introduction of data-plane soak tests aiming at benchmarking long duration stability of OPNFV platform
• Introduction of security tests by cooperating with Moon project to validate the software security based authentication schemes
• Introduction of multi-stack storage tests and Storperf storage test
• Testing framework provides local supports for preparing images for openstack resulting in offline running supports for Bottlenecks

These tests cases and refactoring further enhance the capability of Bottlenecks project and let it be adaptable to different usages.

1.1.8. Reason for Euphrates¶

• Introduction of a simple monitoring module, i.e., Prometheus+Collectd+Node+Grafana to monitor the system behavior when executing stress tests.
• Support VNF scale up/out tests to verify NFVI capability to adapt the resource consuming.
• Extend Life-cycle test to data-plane to validate the system capability to handle concurrent networks usage.
• Testing framework is revised to support installer-agnostic testing.

These enhancements and test cases help the end users to gain more comprehensive understanding of the SUT. Graphic reports of the system behavior additional to test cases are provided to indicate the confidence level of SUT. Installer-agnostic testing framework allow end user to do stress testing adaptively over either Open Source or commercial deployments.

1.1.9. Known restrictions/issues¶

• Bottlenecks uses Yardstick to do stress tests by iteratively calling yardstick running test cases and in the meantime increasing load.

  • Sometimes, Yardstick just waits for the test environment preparing.

  This cause troubles since it seams to get Yardstick into a loop to keep waiting. For OPNFV CI, this loop will be automatically stopped because of the default timeout setting. However, for local testing, user should stop this loop manually.

  • Sometimes, Yardstick will return empty test results with test flag indicating test is excuted succefully.

  It maybe due to the environment issue or poor internet connection causing testing tools are not installed successfully.

• Sometimes, a process will go to sleep state. In this case when a running tool go to sleep state, we try to call it twice. Normally, it will response. This applies to the traffic generator, i.e., netperf.

1.1.10. Test results¶

Test results are available in:

• jenkins logs on CI: https://build.opnfv.org/ci/view/bottlenecks/

The test results are reported to MongoDB. An example is given below.
