4 Tested Topologies VIRL
\r
5 ----------------------
\r
7 CSIT Honeycomb functional tests are executed on virtualized topologies created
\r
8 using Virtual Internet Routing Lab (VIRL) simulation platform contributed by
\r
9 Cisco. VIRL runs on physical baremetal servers hosted by LF FD.io project. All
\r
10 tests are executed in two node logical test topology - Traffic Generator (TG)
\r
11 node and Systems Under Test (SUT1) node connected in a loop. Logical test
\r
12 topology is shown in the figure below.

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

124 Total 111 Honeycomb tests in the CSIT |release|.
\r
126 Operational data in Honeycomb should mirror configuration data at all times.
\r
127 Because of this, test cases follow this general pattern:
\r
129 #. read operational data of the feature using restconf.
\r
130 #. read status of the feature using VPP API dump.
\r
131 #. modify configuration of the feature using restconf.
\r
132 #. verify changes to operational data using restconf.
\r
133 #. verify changes using VPP API dump.
\r
135 Test cases involving network interfaces utilize the first two interfaces on
