| CHO TEST |
| |
| Summary: |
| This is a long-term regression test that is aimed to run |
| for weeks at a time. It's goal is to find memory leaks or bugs that |
| otherwise cannot be easily seen with short-term tests. The following |
| is an overview of the steps that are performed in this test. |
| Steps: |
| - Discover IPv4 and IPv6 hosts |
| - Add host intents |
| - Ping all hosts |
| - Bring links down |
| - Ping all hosts |
| - Bring links back up |
| - Ping all hosts |
| - remove intents |
| |
| These steps are iterated over and over again. The number of iterations can |
| be found in the params file. |
| |
| Topology: |
| Att topology - 25 switches and 25 hosts and its structure is designed to simulate |
| a real world configuration, |
| Chordal topology - 25 swithces and 25 hosts and because of its chordal graph structure, |
| it's particulary useful in testing the rerouting capability of ONOS. |
| Leaf-spine topology - 78 switches and 68 hosts and designed to simulate modern data centers. |
| |
| Pre-requisites: |
| To run out-of-the box this test requires 3 NODES. The cell file |
| must be passed through the startup test command, e.g., |
| |
| ./cli.py run CHOtest onoscell <cell name>. |
| |
| Passwordless login must be set from TestStation "admin" root user. |
| This test relies on the topology files to start Mininet located in |
| the Dependency folder. Be sure to check that each topology file can |
| be loaded properly by Mininet by using this command: |
| |
| sudo ~/<Dependency path>/<topology name> |
