(c) OPNFV, Intel Corporation, AT&T and others. + +Step driven tests +================= + +In general, test scenarios are defined by a ``deployment`` used in the particular +test case definition. 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.
