+The service_outage_time of "nova image-list" is 0 seconds, while the
+process_recover_time of "nova-api" is 300 seconds which equals the running time
+of this test case, that means the "nova-api" service can't automatiocally
+recover itself.
+
+Detailed test results
+---------------------
+All "nova-api" process on the selected controller node was killed, and results
+of two monitors were collected. Specifically, the results of "nova image-list"
+request were collected from compute node and the status of "nova-api" process
+were collected from the selected controller node.
+
+Each monitor was running in a single process. The running time of each monitor
+was about 300 seconds with no waiting time between twice monitor running. For
+"nova image-list", the running times is 127, that's to say there is one
+openstack command request every 2.36 seconds; while the running times is 141
+for "nova-api" process checking, the accurancy is about 2.13 seconds.
+
+The outage time of each monitor, which the name is "service_outage_time" for
+"openstack-cmd" monitor and "process_recover_time" for "process" monitor, is
+defined as the duration from the begin time of the first failure request to the
+end time of the last failure request.
+
+All "nova image-list" requestes were success, so the service_outage_time of
+"nova image-list" is 0 second, while "nova-api" processes were not running for
+all "process" checking, so the process_recover_time of "nova-api" is 300s.
+
+Rationale for decisions
+-----------------------
+The service_outage_time is 0 second, that means the failover time of openstack
+service is less than 2.36s, which is the period of each request. However, the
+process_recover_time equals test case runing time, that means the process is
+not automatically recovered, so this test case is fail.
+
+
+TC025
+-----
+This test case verifies the high availability of controller node. When one of
+the controller node abnormally shutdown, the service provided should be OK.
+There are one attacker, "kill-process" which kills all "nova-api" processes,
+and two "openstack-cmd" monitors, one monitoring openstack command
+"nova image-list" and the other monitoring "neutron router-list".
+Please see the test case description document for detail.
