+## Verify OpenStack and Kubernetes
+
+
+### Functest in a nutshell
+
+- verify any kind of OpenStack and Kubernetes deployments
+- conform with upstream rules (OpenStack gate jobs and Kubernetes conformance
+  tests)
+- ensure that the platforms meet Network Functions Virtualization requirements
+
+
+### Functest suites
+
+- as many upstream functional tests as possible (e.g. Tempest,
+  neutron-tempest-api, Barbican, Patrole...)
+- upstream API and dataplane benchmarking tools (Rally, Vmtp and Shaker)
+- additional VNF deployments and testing (vIMS, vRouter and vEPC)
+
+**Dovetail only runs few Functest functional tests and then we have to verify
+any OPNFV-certified scenarios via Functest anyway**
+
+
+### What's new in Functest?
+
+- new testcases were quickly integrated in Functest: Patrole, Barbican, Shaker,
+  ...
+- all testcases can run in parallel to decrease the overall duration
+- the resources cleaning has been improved
+- **our testcases may be run vs VIM in production**
+- **it includes most of the OpenStack gate jobs**
+
+
+### Support of OS and K8s master
+
+| Functest | OpenStack   | Kubernetes |
+| :------: | :---------: | :--------: |
+| master   | master      | master     |
+| hunter   | rocky       | v1.11.3    |
+| gambia   | queens      | v1.11.3    |

+
+## Reuse of OPNFV
+
+
+### Xtesting in a nutshell
+
+- allow the developer to work only on the test suites without diving into CI/CD
+  integration
+- simplify test integration in a complete LFN-based CI/CD toolchain (e.g.
+  Jenkins, Testing Containers, Test API and dashboard)
+- allow a proper design and verify multiple components in the same CI/CD
+  toolchain (OpenStack, Kubernetes, ONAP, etc.)
+
+**Easy to use and very useful for any CI/CD toochain (unlinked to Infrastrure)**
+
+
+### A user story ONAP
+
+- all tests are run by a specialized Docker container(**<100 MB**) instead of
+the classical ONAP testing virtual machine (**> 1GB**).
+- the container mainly inherits from opnfv/xtesting and is completed by:
+  - Python dependencies
+  - all ONAP Robot Framework files retrieved from the original repositories
+  - testcases.yaml describing the testcases
+
+[Orange-OpenSource/xtesting-onap-robot](https://github.com/Orange-OpenSource/xtesting-onap-robot/)  
+
+
+###  What's new in Xtesting?
+
+- new ansible roles and playbooks have been developed to allow **deploying your
+  full CI/CD toolchains in few minutes** (Jenkins, Minio, TestAPI, MongoDB and
+  Docker registry)
+
+```bash
+virtualenv xtesting
+. xtesting/bin/activate
+pip install ansible docker
+ansible-galaxy install collivier.xtesting
+git clone https://gerrit.opnfv.org/gerrit/functest-xtesting functest-xtesting-src
+ansible-playbook functest-xtesting-src/ansible/site.yml
+deactivate
+```
+
+**They are already reused in Functest and by Orange out of the
+Infrastrure domain**
+
+
+
+## Collect results
+
+
+### OPNFV Test Database in a nutshell
+
+- it's a fair comparison of Neutron implementations (Agents vs SDN
+  controller)
+- it stores all verification results and all performance data from different
+  hardware over the world which could be easily postprocessed
+- it could be very useful to select the adequate opensource solutions
+  regarding metrics and capabilities
+
+
+### which Neutron backend?
+
+- most Neutron standalone and OVN scenarios pass Functest decently
+- no ODL scenarios pass the advanced testcases (benchmarking tools and
+  VNFs). It's still unclear if it's due to the Installers, ODL or POD
+  misconfigurations.
+- no Tungsten Fabric is released in Gambia
+
+**We expected that ODL results would have improved before the first Gambia
+  corrective**
+
+
+### Contrail testing (out of OPNFV)
+
+- **3.X 4.X**: mostly verified except some functional tests about
+  visibility which fail due to the falsy admin role (they can be easily
+  blacklisted)
+- **5.X**: a limited set of bugs in Contrail mostly forbid running few
+  functional tests and benchmarking tools:
+  - wrong external network listing
+  - Contrail doesn't allow booting a VM without network (and elects the wrong
+    network)
+
+
+### And performance?
+
+- OVS DPDK is not fully integrated by an OPNFV installer (Fuel is in a good
+  shape to support it)
+- the only scenario including VPP is not part of Gambia
+
+**From the time being, we can't evaluate the benefits of OVS DPDK or VPP thanks
+  to OPNFV**
+
+
+
+## Conclusion
+
+
+### Gambia
+
+- Functest and Xtesting are powerful and easy to (re)use (containers, jenkins
+  jobs, ansible playbooks, Raspberry PI, etc.).
+- the number of installers and scenarios decreased in Gambia (it's still
+  unclear regarding the overall quality). **What about OPNFV Test Database if
+  it decreases again in 2019?**
+
+
+### And beyond
+
+- test frameworks are now considered as crucial for OPNFV (see [Last OPNFV Marketing update](https://wiki.opnfv.org/download/attachments/2925933/OPNFV%20Marketing%20Update%20091818.pptx?version=1&modificationDate=1537228648000&api=v2)) and Functest and Xtesting could be
+already widely reused out of OPNFV
+- the new test-driven approach as proposed by the [OPNFV Strategic Plan](https://wiki.opnfv.org/download/attachments/2925933/OPNFV%20Strategy%20and%20Plan%20v0.5.pptx?version=1&modificationDate=1540961098000&api=v2) could increase **the quality of all
+scenarios**. But we are also suggesting to let the installers decide their
+test cases.
