Introduction
~~~~~~~~~~~~
Robot Framework is a generic open source automation framework for acceptance
testing, acceptance test driven development (ATDD), and robotic process
automation (RPA). This framework is widely used in ONAP.
The full documentation of robot can be found in https://robotframework.org/.

In ONAP, Robot scripts have been developed to validate the components, provision
and run end to end tests.

The robot scripts can be retrieved in the ONAP testsuite repository: https://git.onap.org/testsuite/

A Robot pod is part of the ONAP default installation.
This pod includes the robot framework and the needed scripts cloned from the
testsuite repository.
Additional scripts are created during the installation in order to simplify
the launch of the different tests and are loacted in /opt/oom/kubernetes/robots.

From one of the kubernetes controller, you shall see the pod as follows:

::

  $ kubectl get pods -n onap | grep robot
  onap-robot-robot-7fc49977fd-6jblt    1/1     Running    0          9h

You can access the robot configuration through its configmap.

::

  $ kubectl describe cm onap-robot-robot-eteshare-configmap -n onap

You shall see a long list of variables set during the ONAP installation by OOM.
Please note that some of these variables are set thanks to the OOM
overide openstack.yaml file. See the examples described in https://git.onap.org/oom/tree/kubernetes/onap/resources/overrides/openstack.yaml

Verification of the ONAP components
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
ONAP robot healthcheck tests have been created to give a quick feedback on the
status of the ONAP components.

You can run them from one of the kubernetes controller. You need to log on the
machine then perform the following commands:

::

  $ cd /opt/oom/kubernetes/robot
  $ ./ete-k8s.sh onap health

You shall the execution of all the healthcheck launched from bash script hosted
on the kubernetes controller and executed on the robot pod.

At the end you shall see that logs and reporting are automatically generated
by robot and stored on the pod under /share/logs/.
You can retrieve the logs directly from the pods or through the web interface
integrated in the robot pod by typing
http://portal.api.simpledemo.onap.org:30209/logs/ (test/test)

.. figure:: files/robot/robot_logs.png
   :align: center

You shall see 3 files:

* log.html
* output.xml
* report.html

A new directory will be created after each run.

log.html should look like

.. figure:: files/robot/robot_report_logs.png
   :align: center

When the testsuite is passed, the reporting page is green.

.. figure:: files/robot/robot_report_ok.png
   :align: center

You can click on the test case to get details.

.. figure:: files/robot/robot_report_details.png
   :align: center

If one of the test is FAIL, the generated web reporting page will be red.

.. figure:: files/robot/robot_report_ko.png
   :align: center

Lots of tags have been created for healthcheck tests. You may replace health by
core, small, medium, 3rdparty, health-sdc, health-multicloud,...

See https://git.onap.org/testsuite/tree/robot/testsuites/health-check.robot to
get all the tags.

As an illustration, healthcheck core traces should be displayed as follows.

Onboard and Instantiate VNF/PNF with Robot
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Robot scripts have been also created to provision components and perform end
to end tests.
All the robot scripts are hosted on the tesuite repository and deal with various
test cases and/or components.

It is, for instance possible to test the onboarding of the vFirewall model in
the SDC by running the command:

::

  $ ete-k8s.sh onap healthdist

If you consider the ete-k8s.sh script, the following testsuites are referenced:

* cds.robot: cds
* clamp.robot: clamp
* demo.robot: InitDemo, InitCustomer, APPCCDTPreloadDemo, APPCMountPointDemo, DistributeDemoVFWDT, DistributeVFWNG
* health-check.robot: health, core, small, medium, 3rdparty, api, datarouter, externalapi, health-aaf,...
* hvves.robot: HVVES, ete
* model-distribution-vcpe.robot: distributevCPEResCust
* model-distribution.robot: distribute, distributeVFWDT, distributeVLB
* oof-cmso.robot, oof-homing.robot, oof-has.robot: oof related tests
* pnf-registration.robot: ete, pnf_registrate
* post-install-tests.robot dmaapacl, postinstall
* update_onap_page.robot: UpdateWebPage
* vnf-orchestration-direct-so.robot: instantiateVFWdirectso
* vnf-orchestration.robot: instantiate, instantiateNoDelete, stability72hr

If you use the demo-k8s.s script, you may see the following options:

* init_robot
* init
* init_customer
* distribute
* preload
* appc
* instantiateVFW
* instantiateVFWdirectso
* deleteVNF
* heatbridge
* cds
* distributeVFWNG
* distributeDemoVFWDT
* instantiateDemoVFWDT
* vfwclosedloop

See :ref:`Verified Use Cases and Functional Requirements <docs_usecases>` to see
how to use these scripts. Some of them may need specific prerequisites on the
environment and may support specific versions and/or configurations.


Develop your own Robot scripts
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
A dedicated wiki page has been created to help people to design and write their
own robot scripts within ONAP context (https://wiki.onap.org/display/DW/Robot+Framework+Development+Guide)
It is also possible to contact the integration team to get support.
