-\r
-Tested Virtual Topologies\r
--------------------------\r
-\r
-CSIT Honeycomb functional tests are executed on virtualized topologies created\r
-using Virtual Internet Routing Lab (VIRL) simulation platform contributed by\r
-Cisco. VIRL runs on physical baremetal servers hosted by LF FD.io project. All\r
-tests are executed in two node logical test topology - Traffic Generator (TG)\r
-node and Systems Under Test (SUT1) node connected in a loop. Logical test\r
-topology is shown in the figure below.\r

-SUT1 is a VM (Ubuntu or Centos, depending on the test suite), TG is a Traffic\r
-Generator (TG, another Ubuntu VM). SUTs run Honeycomb and VPP SW applications\r
-in Linux user-mode as a Device Under Test (DUT) within the VM. TG runs Scapy\r
-SW application as a packet Traffic Generator. Logical connectivity between\r
-SUTs and to TG is provided using virtual NICs using VMs' virtio driver.\r
-\r
-Virtual testbeds are created on-demand whenever a verification job is started\r
-(e.g. triggered by the gerrit patch submission) and destroyed upon completion\r
-of all functional tests. Each node is a Virtual Machine and each connection\r
-that is drawn on the diagram is available for use in any test case. During the\r
-test execution, all nodes are reachable thru the Management network connected\r
-to every node via dedicated virtual NICs and virtual links (not shown above\r
-for clarity).\r

-\r
-Total 111 Honeycomb tests in the CSIT |release|.\r
-\r
-Operational data in Honeycomb should mirror configuration data at all times.\r
-Because of this, test cases follow this general pattern:\r
-\r
-#. read operational data of the feature using restconf.\r
-#. read status of the feature using VPP API dump.\r
-#. modify configuration of the feature using restconf.\r
-#. verify changes to operational data using restconf.\r
-#. verify changes using VPP API dump, OR\r
-#. send a packet to VPP node and observe behaviour to verify configuration\r
-\r
-Test cases involving network interfaces utilize the first two interfaces on\r
-the DUT node.\r
-\r
-Functional Tests Naming\r
------------------------\r
-\r
-CSIT |release| introduced a common structured naming convention for all\r
-performance and functional tests. This change was driven by substantially\r
-growing number and type of CSIT test cases. Firstly, the original practice did\r
-not always follow any strict naming convention. Secondly test names did not\r
-always clearly capture tested packet encapsulations, and the actual type or\r
-content of the tests. Thirdly HW configurations in terms of NICs, ports and\r
-their locality were not captured either. These were but few reasons that drove\r
-the decision to change and define a new more complete and stricter test naming\r
-convention, and to apply this to all existing and new test cases.\r
-\r
-The new naming should be intuitive for majority of the tests. The complete\r
-description of CSIT test naming convention is provided on `CSIT test naming\r
-page <https://wiki.fd.io/view/CSIT/csit-test-naming>`_.\r
-\r
-Here few illustrative examples of the new naming usage for functional test\r
-suites:\r
-\r
-#. **Physical port to physical port - a.k.a. NIC-to-NIC, Phy-to-Phy, P2P**\r
-\r
-    - *eth2p-ethip4-ip4base-func.robot* => 2 ports of Ethernet, IPv4 baseline\r
-      routed forwarding, functional tests.\r
-\r
-#. **Physical port to VM (or VM chain) to physical port - a.k.a. NIC2VM2NIC,\r
-   P2V2P, NIC2VMchain2NIC, P2V2V2P**\r
-\r
-    - *eth2p-ethip4vxlan-l2bdbasemaclrn-eth-2vhost-1vm-func.robot* => 2 ports of\r
-      Ethernet, IPv4 VXLAN Ethernet, L2 bridge-domain switching to/from two vhost\r
-      interfaces and one VM, functional tests.\r

+Total 213 Honeycomb functional tests in the |csit-release|.
+
+Operational data in Honeycomb should mirror configuration data at all
+times. Because of this, test cases follow this general pattern:
+
+#. read operational data of the feature using restconf.
+#. read status of the feature using VPP API dump.
+#. modify configuration of the feature using restconf.
+#. verify changes to operational data using restconf.
+#. verify changes using VPP API dump, OR
+#. send a packet to VPP node and observe behaviour to verify configuration.
+
+Test cases involving network interfaces utilize the first two interfaces
+on the DUT node.
+
+Functional Tests Naming
+-----------------------
+
+|csit-release| follows a common structured naming convention for all
+performance and system functional tests, introduced in CSIT-17.01.
+
+The naming should be intuitive for majority of the tests. Complete
+description of CSIT test naming convention is provided on
+:ref:`csit_test_naming`.
