+Yardstick Test Case Description TC058

+|OpenStack Controller Virtual Router Service High Availability |
++==============+==============================================================+
+|test case id | OPNFV_YARDSTICK_TC058:OpenStack Controller Virtual Router |
+| | Service High Availability |
++--------------+--------------------------------------------------------------+
+|test purpose | This test case will verify the high availability of virtual |
+| | routers(L3 agent) on controller node. When a virtual router |
+| | service on a specified controller node is shut down, this |
+| | test case will check whether the network of virtual machines |
+| | will be affected, and whether the attacked virtual router |
+| | service will be recovered. |
++--------------+--------------------------------------------------------------+
+|test method | This test case kills the processes of virtual router service |
+| | (l3-agent) on a selected controller node(the node holds the |
+| | active l3-agent), then checks whether the network routing |
+| | of virtual machines is OK and whether the killed service |
+| | will be recovered. |
++--------------+--------------------------------------------------------------+
+|attackers | In this test case, an attacker called "kill-process" is |
+| | needed. This attacker includes three parameters: |
+| | 1) fault_type: which is used for finding the attacker's |
+| | scripts. It should be always set to "kill-process" in this |
+| | test case. |
+| | 2) process_name: which is the process name of the load |
+| | balance service. If there are multiple processes use the |
+| | same name on the host, all of them are killed by this |
+| | attacker. |
+| | 3) host: which is the name of a control node being attacked. |
+| | |
+| | In this case, this process name should set to "l3agent" , |
+| | for example |
+| | -fault_type: "kill-process" |
+| | -process_name: "l3agent" |
+| | -host: node1 |
++--------------+--------------------------------------------------------------+
+|monitors | In this test case, two kinds of monitor are needed: |
+| | 1. the "ip_status" monitor that pings a specific ip to check |
+| | the connectivity of this ip, which needs two parameters: |
+| | 1) monitor_type: which is used for finding the monitor class |
+| | and related scripts. It should be always set to "ip_status" |
+| | for this monitor. |
+| | 2) ip_address: The ip to be pinged. In this case, ip_address |
+| | will be either an ip address of external network or an ip |
+| | address of a virtual machine. |
+| | 3) host: The node on which ping will be executed, in this |
+| | case the host will be a virtual machine. |
+| | |
+| | 2. the "process" monitor check whether a process is running |
+| | on a specific node, which needs three parameters: |
+| | 1) monitor_type: which used for finding the monitor class |
+| | and related scripts. It should be always set to "process" |
+| | for this monitor. |
+| | 2) process_name: which is the process name for monitor. In |
+| | this case, the process-name of monitor2 should be "l3agent" |
+| | 3) host: which is the name of the node running the process |
+| | |
+| | e.g. |
+| | monitor1-1: |
+| | -monitor_type: "ip_status" |
+| | -host: 172.16.0.11 |
+| | -ip_address: 172.16.1.11 |
+| | monitor1-2: |
+| | -monitor_type: "ip_status" |
+| | -host: 172.16.0.11 |
+| | -ip_address: 8.8.8.8 |
+| | monitor2: |
+| | -monitor_type: "process" |
+| | -process_name: "l3agent" |
+| | -host: node1 |
++--------------+--------------------------------------------------------------+
+|metrics | In this test case, there are two metrics: |
+| | 1)service_outage_time: which indicates the maximum outage |
+| | time (seconds) of the specified Openstack command request. |
+| | 2)process_recover_time: which indicates the maximum time |
+| | (seconds) from the process being killed to recovered |
++--------------+--------------------------------------------------------------+
+|test tool | None. Self-developed. |

+|configuration | This test case needs two configuration files: |
+| | 1) test case file: opnfv_yardstick_tc058.yaml |
+| | -Attackers: see above "attackers" description |
+| | -Monitors: see above "monitors" description |
+| | -Steps: the test case execution step, see "test sequence" |
+| | description below |
+| | |
+| | 2)POD file: pod.yaml |
+| | The POD configuration should record on pod.yaml first. |
+| | the "host" item in this test case will use the node name in |
+| | the pod.yaml. |

+|test sequence | description and expected result |
+| | |
++--------------+--------------------------------------------------------------+
+|pre-test | The test case image needs to be installed into Glance |
+|conditions | with cachestat included in the image. |
+| | |
++--------------+--------------------------------------------------------------+
+|step 1 | Two host VMs are booted, these two hosts are in two different|
+| | networks, the networks are connected by a virtual router |
+| | |
++--------------+--------------------------------------------------------------+
+|step 1 | start monitors: |
+| | each monitor will run with independently process |
+| | |
+| | Result: The monitor info will be collected. |
+| | |
++--------------+--------------------------------------------------------------+
+|step 2 | do attacker: connect the host through SSH, and then execute |
+| | the kill process script with param value specified by |
+| | "process_name" |
+| | |
+| | Result: Process will be killed. |
+| | |
++--------------+--------------------------------------------------------------+
+|step 4 | stop monitors after a period of time specified by |
+| | "waiting_time" |
+| | |
+| | Result: The monitor info will be aggregated. |
+| | |
++--------------+--------------------------------------------------------------+
+|step 5 | verify the SLA |
+| | |
+| | Result: The test case is passed or not. |
+| | |
++--------------+------+----------------------------------+--------------------+
+|post-action | It is the action when the test cases exist. It will check |
+| | the status of the specified process on the host, and restart |
+| | the process if it is not running for next test cases. |
+| | Virtual machines and network created in the test case will |
+| | be destoryed. |
+| | |
++--------------+------+----------------------------------+--------------------+
+|test verdict | Fails only if SLA is not passed, or if there is a test case |
+| | execution problem. |
