+Scale out a VNF Instance
+    [Documentation]    Test ID: 5.x.y.x
+    ...    Test title: Scale out VNF operation
+    ...    Test objective: The objective is to test a scale out of an existing VNF instance
+    ...    Pre-conditions: VNF instance in INSTANTIATED state (Test ID: 5.a.b.c)
+    ...    Reference: section 5.4.5 - SOL003 v2.4.1
+    ...    Config ID: Config_prod_VNFM
+    ...    Applicability: Scale operation is supported for the VNF (as capability in the VNFD)
+    ...    NFVO is not subscribed for
+    ...    Post-Conditions: VNF instance still in INSTANTIATED state and VNF was scaled
