The chosen deployment scenario will take care of the vSwitch -configuration, deployment of VNFs and it can also affect configuration of a traffic -generator. In order to allow a more flexible way of testcase scripting, VSPERF supports -a detailed step driven testcase definition. It can be used to configure and -program vSwitch, deploy and terminate VNFs, execute a traffic generator, -modify a VSPERF configuration, execute external commands, etc. - -Execution of step driven tests is done on a step by step work flow starting -with step 0 as defined inside the test case. Each step of the test increments -the step number by one which is indicated in the log. - -.. code-block:: console - - (testcases.integration) - Step 0 'vswitch add_vport ['br0']' start - -Step driven tests can be used for both performance and integration testing. -In case of integration test, each step in the test case is validated. If a step -does not pass validation the test will fail and terminate. The test will continue -until a failure is detected or all steps pass. A csv report file is generated after -a test completes with an OK or FAIL result. - -In case of performance test, the validation of steps is not performed and -standard output files with results from traffic generator and underlying OS -details are generated by vsperf. - -Step driven testcases can be used in two different ways: - - # description of full testcase - in this case ``clean`` deployment is used - to indicate that vsperf should neither configure vSwitch nor deploy any VNF. - Test shall perform all required vSwitch configuration and programming and - deploy required number of VNFs. - - # modification of existing deployment - in this case, any of supported - deployments can be used to perform initial vSwitch configuration and - deployment of VNFs. Additional actions defined by TestSteps can be used - to alter vSwitch configuration or deploy additional VNFs. After the last - step is processed, the test execution will continue with traffic execution. - -Test objects and their functions --------------------------------- - -Every test step can call a function of one of the supported test objects. The list -of supported objects and their most common functions follows: - - * ``vswitch`` - provides functions for vSwitch configuration - - List of supported functions: - - * ``add_switch br_name`` - creates a new switch (bridge) with given ``br_name`` - * ``del_switch br_name`` - deletes switch (bridge) with given ``br_name`` - * ``add_phy_port br_name`` - adds a physical port into bridge specified by ``br_name`` - * ``add_vport br_name`` - adds a virtual port into bridge specified by ``br_name`` - * ``del_port br_name port_name`` - removes physical or virtual port specified by - ``port_name`` from bridge ``br_name`` - * ``add_flow br_name flow`` - adds flow specified by ``flow`` dictionary into - the bridge ``br_name``; Content of flow dictionary will be passed to the vSwitch. - In case of Open vSwitch it will be passed to the ``ovs-ofctl add-flow`` command. - Please see Open vSwitch documentation for the list of supported flow parameters. - * ``del_flow br_name [flow]`` - deletes flow specified by ``flow`` dictionary from - bridge ``br_name``; In case that optional parameter ``flow`` is not specified - or set to an empty dictionary ``{}``, then all flows from bridge ``br_name`` - will be deleted. - * ``dump_flows br_name`` - dumps all flows from bridge specified by ``br_name`` - * ``enable_stp br_name`` - enables Spanning Tree Protocol for bridge ``br_name`` - * ``disable_stp br_name`` - disables Spanning Tree Protocol for bridge ``br_name`` - * ``enable_rstp br_name`` - enables Rapid Spanning Tree Protocol for bridge ``br_name`` - * ``disable_rstp br_name`` - disables Rapid Spanning Tree Protocol for bridge ``br_name`` - - Examples: - - .. code-block:: python - - ['vswitch', 'add_switch', 'int_br0'] - - ['vswitch', 'del_switch', 'int_br0'] - - ['vswitch', 'add_phy_port', 'int_br0'] - - ['vswitch', 'del_port', 'int_br0', '#STEP[2][0]'] - - ['vswitch', 'add_flow', 'int_br0', {'in_port': '1', 'actions': ['output:2'], - 'idle_timeout': '0'}], - - ['vswitch', 'enable_rstp', 'int_br0'] - - * ``vnf[ID]`` - provides functions for deployment and termination of VNFs; Optional - alfanumerical ``ID`` is used for VNF identification in case that testcase - deploys multiple VNFs. - - List of supported functions: - - * ``start`` - starts a VNF based on VSPERF configuration - * ``stop`` - gracefully terminates given VNF - - Examples: - - .. code-block:: python - - ['vnf1', 'start'] - ['vnf2', 'start'] - ['vnf2', 'stop'] - ['vnf1', 'stop'] - - * ``trafficgen`` - triggers traffic generation - - List of supported functions: - - * ``send_traffic traffic`` - starts a traffic based on the vsperf configuration - and given ``traffic`` dictionary.

This object doesn't have - any functions. Once reached, vsperf will pause test execution and waits - for press of ``Enter key``. It can be used during testcase design - for debugging purposes. - - Examples: - - .. code-block:: python - - ['wait'] - -Test Macros ------------ - -Test profiles can include macros as part of the test step. Each step in the -profile may return a value such as a port name. Recall macros use #STEP to -indicate the recalled value inside the return structure.

In the future, Yardstick will -support two options of vswitchperf testcase execution: - -- plugin mode, which will execute native vswitchperf testcases; Tests will - be executed natively by vsperf, and test results will be processed and - reported by yardstick. -- traffic generator mode, which will run vswitchperf in **trafficgen** - mode only; Yardstick framework will be used to launch VNFs and to configure - flows to ensure, that traffic is properly routed. This mode will allow to - test OVS performance in real world scenarios. - -In Colorado release only the traffic generator mode is supported. - -Yardstick Installation -^^^^^^^^^^^^^^^^^^^^^^ - -In order to run Yardstick testcases, you will need to prepare your test -environment. Please follow the `installation instructions -<http://artifacts.opnfv.org/yardstick/docs/user_guides_framework/index.html>`__ -to install the yardstick. - -Please note, that yardstick uses OpenStack for execution of testcases. -OpenStack must be installed with Heat and Neutron services. Otherwise -vswitchperf testcases cannot be executed. - -VM image with vswitchperf -^^^^^^^^^^^^^^^^^^^^^^^^^ - -A special VM image is required for execution of vswitchperf specific testcases -by yardstick. It is possible to use a sample VM image available at OPNFV -artifactory or to build customized image. - -Sample VM image with vswitchperf -~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ - -Sample VM image is available at vswitchperf section of OPNFV artifactory -for free download: - -.. code-block:: console - - $ wget http://artifacts.opnfv.org/vswitchperf/vnf/vsperf-yardstick-image.qcow2 - -This image can be used for execution of sample testcases with dummy traffic -generator. - -**NOTE:** Traffic generators might require an installation of client software. -This software is not included in the sample image and must be installed by user. - -**NOTE:** This image will be updated only in case, that new features related -to yardstick integration will be added to the vswitchperf. - -Preparation of custom VM image -~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ - -In general, any Linux distribution supported by vswitchperf can be used as -a base image for vswitchperf. One of the possibilities is to modify vloop-vnf -image, which can be downloaded from `<http://artifacts.opnfv.org/vswitchperf.html/>`__ -(see :ref:`vloop-vnf`). - -Please follow the :ref:`vsperf-installation` to -install vswitchperf inside vloop-vnf image. As vswitchperf will be run in -trafficgen mode, it is possible to skip installation and compilation of OVS, -QEMU and DPDK to keep image size smaller. - -In case, that selected traffic generator requires installation of additional -client software, please follow appropriate documentation. For example in case -of IXIA, you would need to install IxOS and IxNetowrk TCL API. - -VM image usage -~~~~~~~~~~~~~~ - -Image with vswitchperf must be uploaded into the glance service and -vswitchperf specific flavor configured, e.g.: - -.. code-block:: console - - $ glance --os-username admin --os-image-api-version 1 image-create --name \ - vsperf --is-public true --disk-format qcow2 --container-format bare --file \ - vsperf-yardstick-image.qcow2 - - $ nova --os-username admin flavor-create vsperf-flavor 100 2048 25 1 - -Testcase execution -^^^^^^^^^^^^^^^^^^ - -After installation, yardstick is available as python package within yardstick -specific virtual environment. It means, that yardstick environment must be -enabled before the test execution, e.g.: - -.. code-block:: console - - source ~/yardstick_venv/bin/activate - - -Next step is configuration of OpenStack environment, e.g. in case of devstack: - -.. code-block:: console - - source /opt/openstack/devstack/openrc - export EXTERNAL_NETWORK=public - -Vswitchperf testcases executable by yardstick are located at vswitchperf -repository inside ``yardstick/tests`` directory.

Lot of options -are identical to the vswitchperf parameters passed through ``--test-params`` -argument. Following options are supported: - -- **frame_size** - a packet size for which test should be executed; - Multiple packet sizes can be tested by modification of Sequence runner - section inside YAML definition. Default: '64' -- **conf_file** - sets path to the vswitchperf configuration file, which will be - uploaded to VM; Default: '~/vsperf-yardstick.conf' -- **setup_script** - sets path to the setup script, which will be executed - during setup and teardown phases -- **trafficgen_port1** - specifies device name of 1st interface connected to - the trafficgen -- **trafficgen_port2** - specifies device name of 2nd interface connected to - the trafficgen -- **external_bridge** - specifies name of external bridge configured in OVS; - Default: 'br-ex' -- **test_params** - specifies a string with a list of vsperf configuration - parameters, which will be passed to the ``--test-params`` CLI argument; - Parameters should be stated in the form of ``param=value`` and separated - by a semicolon. Configuration of traffic generator is driven by ``TRAFFIC`` - dictionary, which can be also updated by values defined by ``test_params``. - Please check VSPERF documentation for details about available configuration - parameters and their data types. - In case that both **test_params** and **conf_file** are specified, - then values from **test_params** will override values defined - in the configuration file. - -In case that **trafficgen_port1** and/or **trafficgen_port2** are defined, then -these interfaces will be inserted into the **external_bridge** of OVS. It is -expected, that OVS runs at the same node, where the testcase is executed. In case -of more complex OpenStack installation or a need of additional OVS configuration, -**setup_script** can be used. - -**NOTE** It is essential to specify a configuration for selected traffic generator. -In case, that standalone testcase is created, then traffic generator can be -selected and configured directly in YAML file by **test_params**. On the other -hand, if multiple testcases should be executed with the same traffic generator -settings, then a customized configuration file should be prepared and its name -passed by **conf_file** option. - -Section runner -~~~~~~~~~~~~~~ - -Yardstick supports several `runner types -<http://artifacts.opnfv.org/yardstick/docs/userguide/architecture.html#runner-types>`__. -In case of vswitchperf specific TCs, **Sequence** runner type can be used to -execute the testcase for given list of frame sizes. - - -Section sla -~~~~~~~~~~~ - -In case that sla section is not defined, then testcase will be always -considered as successful. On the other hand, it is possible to define a set of -test metrics and their minimal values to evaluate test success. Any numeric -value, reported by vswitchperf inside CSV result file, can be used. -Multiple metrics can be defined as a coma separated list of items. Minimal -value must be set separately for each metric. - -e.g.: - -.. code-block:: yaml - - sla: - metrics: 'throughput_rx_fps,throughput_rx_mbps' - throughput_rx_fps: 500000 - throughput_rx_mbps: 1000 - -In case that any of defined metrics will be lower than defined value, then -testcase will be marked as failed. Based on ``action`` policy, yardstick -will either stop test execution (value ``assert``) or it will run next test -(value ``monitor``). - -**NOTE** The throughput SLA (or any other SLA) cannot be set to a meaningful -value without knowledge of the server and networking environment, possibly -including prior testing in that environment to establish a baseline SLA level -under well-understood circumstances. |
