- -The document ETSI GS NFV-TST001_, "Pre-deployment Testing; Report on Validation -of NFV Environments and Services", recommends methods for pre-deployment -testing of the functional components of an NFV environment. - -The Yardstick project implements the methodology described in chapter 6, "Pre- -deployment validation of NFV infrastructure". - -The methodology consists in decomposing the typical :term:`VNF` work-load -performance metrics into a number of characteristics/performance vectors, which -each can be represented by distinct test-cases. - -The methodology includes five steps: - -* *Step1:* Define Infrastruture - the Hardware, Software and corresponding - configuration target for validation; the OPNFV infrastructure, in OPNFV - community labs. - -* *Step2:* Identify :term:`VNF` type - the application for which the - infrastructure is to be validated, and its requirements on the underlying - infrastructure. - -* *Step3:* Select test cases - depending on the workload that represents the - application for which the infrastruture is to be validated, the relevant - test cases amongst the list of available Yardstick test cases. - -* *Step4:* Execute tests - define the duration and number of iterations for the - selected test cases, tests runs are automated via OPNFV Jenkins Jobs. - -* *Step5:* Collect results - using the common API for result collection. - -.. seealso:: Yardsticktst_ for material on alignment ETSI TST001 and Yardstick. - -Metrics -======= - -The metrics, as defined by ETSI GS NFV-TST001, are shown in -:ref:`Table1 <table2_1>`, :ref:`Table2 <table2_2>` and -:ref:`Table3 <table2_3>`. - -In OPNFV Colorado release, generic test cases covering aspects of the listed -metrics are available; further OPNFV releases will provide extended testing of -these metrics. -The view of available Yardstick test cases cross ETSI definitions in -:ref:`Table1 <table2_1>`, :ref:`Table2 <table2_2>` and :ref:`Table3 <table2_3>` -is shown in :ref:`Table4 <table2_4>`. -It shall be noticed that the Yardstick test cases are examples, the test -duration and number of iterations are configurable, as are the System Under -Test (SUT) and the attributes (or, in Yardstick nomemclature, the scenario -options). -
