From 801cddd65cad0bd01ea8fec5d33f9e53e17aa62b Mon Sep 17 00:00:00 2001 From: "Benjamin, Max (mb388a)" Date: Fri, 11 Jan 2019 21:09:59 -0500 Subject: validation for vnfs before WorkflowAction starts Removed accidental merge markup from WorkflowActionBB Addition of prevalidation to WorkflowActionBB. Implement more JUnits for validation methods. Implement verification of deleteInstance workflow for VNR configuration dependencies. Added a validation mechanism on a workflow level to check for valid actions.
