For testing purposes, it is possible to use the full MANO stack (NFVO + VNFM) or just the VNFM. Step 3: Test the VNF. For project Clearwater, Functest runs more than 100 default signaling tests covering most vIMS test cases (calls, registration, redirection, busy, and so on). We have talked about a specific VNF, but this approach is pragmatic enough to be applied to other VNFs – open source or proprietary. Using OPNFV as a standard way to onboard VNFs brings great value to the industry because of the complexity of the VNF onboarding landscape. No one vendor or user has the resources or time to perform testing against a full interop matrix. But as a community, this is eminently possible. At this point, it is worth taking a bit of a detour to illustrate the power of open source. The initial
