Integration tests ================= VSPERF includes a set of integration tests defined in conf/integration. These tests can be run by specifying --integration as a parameter to vsperf. Current tests in conf/integration include switch functionality and Overlay tests. Tests in the conf/integration can be used to test scaling of different switch configurations by adding steps into the test case. For the overlay tests VSPERF supports VXLAN, GRE and GENEVE tunneling protocols. Testing of these protocols is limited to unidirectional traffic and P2P (Physical to Physical scenarios). NOTE: The configuration for overlay tests provided in this guide is for unidirectional traffic only. Executing Integration Tests --------------------------- To execute integration tests VSPERF is run with the integration parameter. To view the current test list simply execute the following command: .. code-block:: console ./vsperf --integration --list The standard tests included are defined inside the ``conf/integration/01_testcases.conf`` file. Test Steps ---------- Execution of integration tests are 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 1 - 'vswitch add_switch ['int_br1']' ... OK 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. 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. If the method the test step calls returns a value it can be later recalled, for example: .. code-block:: python { "Name": "vswitch_add_del_vport", "Deployment": "clean", "Description": "vSwitch - add and delete virtual port", "TestSteps": [ ['vswitch', 'add_switch', 'int_br0'], # STEP 0 ['vswitch', 'add_vport', 'int_br0'], # STEP 1 ['vswitch', 'del_port', 'int_br0', '#STEP[1][0]'], # STEP 2 ['vswitch', 'del_switch', 'int_br0'], # STEP 3 ] } This test profile uses the the vswitch add_vport method which returns a string value of the port added. This is later called by the del_port method using the name from step 1. Also commonly used steps can be created as a separate profile. .. code-block:: python STEP_VSWITCH_PVP_INIT = [ ['vswitch', 'add_switch', 'int_br0'], # STEP 0 ['vswitch', 'add_phy_port', 'int_br0'], # STEP 1 ['vswitch', 'add_phy_port', 'int_br0'], # STEP 2 ['vswitch', 'add_vport', 'int_br0'], # STEP 3 ['vswitch', 'add_vport', 'int_br0'], # STEP 4 ] This profile can then be used inside other testcases .. code-block:: python { "Name": "vswitch_pvp", "Deployment": "clean", "Description": "vSwitch - configure switch and one vnf", "TestSteps": STEP_VSWITCH_PVP_INIT + [ ['vnf', 'start'], ['vnf', 'stop'], ] + STEP_VSWITCH_PVP_FINIT } Executing Tunnel encapsulation tests ------------------------------------ The VXLAN OVS DPDK encapsulation tests requires IPs, MAC addresses, bridge names and WHITELIST_NICS for DPDK.
