Generate the documents for test cases and libraries. - Use the phony to force execute the gendocs target (ignore directory exist). - Use for loop to find all robot files and then create documents. Change-Id: Ia5686a559b78dd506aca0b79f0bce0fba4b14c5a
Automated test-suites to validate the stability/functionality of VOLTHA. Tests that reside in here should be written in Robot Framework and Python.
Intended use includes:
Python virtualenv
voltctl - a command line tool to access VOLTHA. Reference - voltctl
kubectl - a command line tool to access your Kubernetes Clusers. Reference
voltctl and kubectl must be properly configured on your system prior to any test executions. The kind-voltha environment will install and configure these tools for you; see below.
Directory is structured as follows:
├── tests └── sanity/ // basic tests that should always pass. Will be used as gating-patchsets └── functional/ // feature/functionality tests that should be implemented as new features get developed └── libraries // shared test keywords (functions) across various test suites └── variables // shared variables across various test suites
An easy way to bring up VOLTHA + BBSim for testing is by using kind-voltha. To set up a minimal environment, first install Docker and the Go programming language. Then run the following commands:
Note: Please make sure you are able to run the docker command, you can run as root or add your running user into docker group.
git clone https://github.com/ciena/kind-voltha cd kind-voltha EXTRA_HELM_FLAGS="--set defaults.image_tag=voltha-2.1" TYPE=minimal WITH_RADIUS=y WITH_BBSIM=y INSTALL_ONOS_APPS=y CONFIG_SADIS=y ./voltha up source minimal-env.sh
The defaults.image_tag value above is used to specify which VOLTHA branch images to pull from Docker Hub. See all available versions in Docker voltha.
Assuming that you have brought up VOLTHA as described above, to run the the sanity tests:
git clone https://github.com/opencord/voltha-system-tests make -C voltha-system-tests sanity-kind
This test execution will generate three report files in voltha-system-tests/tests/sanity (output.xml, report.html, log.html). View the report.html page in a browser to analyze the results.
The make sanity-kind target is equivalent to the following:
ROBOT_PORT_ARGS="-v ONOS_REST_PORT:8181 -v ONOS_SSH_PORT:8101" \ ROBOT_TEST_ARGS="--exclude notready --critical sanity" \ ROBOT_MISC_ARGS="-v num_onus:1" \ make sanity
If you are running the tests in another environment, you can run make sanity with the arguments appropriate for your environment. Look at variables.robot for a list of variables that you may need to override.
Assuming that a POD is available with all the required hardware and connections, we can deploy the POD by following the procedure in this section below.
Deploying POD can be either be manual or automated using Jenkins job.
You can install it manually by following these steps below.
git clone https://github.com/ciena/kind-voltha.git
cd kind-voltha/
EXTRA_HELM_FLAGS='-f $WORKSPACE/${configBaseDir}/${configKubernetesDir}/voltha/${configFileName}.yml' WITH_RADIUS=y WITH_TP=yes DEPLOY_K8S=no INSTALL_KUBECTL=no INSTALL_HELM=no ONOS_TAG=voltha-2.1 ./voltha up
For more information on various environment variables with ./voltha up please check the link here
All functional test cases are placed under functional folder. Voltha_PODTests.robot consists of functional testcases that can be run on a physical POD. Each robot testcase has a description in the Documentation section. The same suite of tests can be run on any POD because parameters needed for the test are written in .yaml file. Instead of hardcoding the POD specific variables in the test case, tests rely on a separate configuration file which describes the POD setup. This .yaml file contains details like the ONUs, OLT, nodes etc. To create a configuration file for your POD, check this example
Input data are stored in the data folder. Few examples of input data could be, test specific sadis configurations, tech profiles etc. Please give appropriate file names to the input files.
To trigger tests on the physical POD
cd voltha-system-tests/tests/functional robot -V <PATH_TO_YOUR_POD_CONFIGURATION_FILE> Voltha_PODTests.robot
Note: PATH_TO_YOUR_POD_CONFIGURATION_FILE should point to the yaml file that describes your POD setup.
Scenarios in each test suite can be associated with a Tag, using which a particular scenario can be invoked during test execution. As an example to execute only one testcase from the test suite you can do something like here
cd voltha-system-tests/tests/functional robot -i test1 -V <PATH_TO_YOUR_POD_CONFIGURATION_FILE> Voltha_PODTests.robot
Most additions should be done by adding keywords to the libraries, then calling these keywords from the tests. Consult a guide on how to write good Robot framework tests. When writing new functions, make sure there is proper documentation for it. Also, follow a good naming convention for any new functions. There are also many keywords/functions available as part of the SEBA test framework which can be found here
Tests should be written in RobotFramework as they need to be integrated with Jenkins test jobs. Libraries can be written in python or RobotFramework.
Make sure that make lint passes, which runs robotframework-lint on any new code that is created.
