Use-Case View
=============
-TBD(kubi)
+Yardstick Use-Case View shows two kinds of users. One is the Tester who will
+do testing in cloud, the other is the User who is more concerned with test result
+and result analyses.
+
+For testers, they will run a single test case or test case suite to verify
+infrastructure compliance or bencnmark their own infrastructure performance.
+Test result will be stored by dispatcher module, three kinds of store method
+(file, influxdb and http) can be configured. The detail information of
+scenarios and runners can be queried with CLI by testers.
+
+For users, they would check test result with four ways.
+
+If dispatcher module is configured as file(default), there are two ways to
+check test result. One is to get result from yardstick.out ( default path:
+/tmp/yardstick.out), the other is to get plot of test result, it will be shown
+if users execute command "yardstick-plot".
+
+If dispatcher module is configured as influxdb, users will check test
+result on Grafana which is most commonly used for visualizing time series data.
+
+If dispatcher module is configured as http, users will check test result
+on OPNFV testing dashboard which use MongoDB as backend.

Process View (Test execution flow)
==================================
-TBD(Limingjiang)
+Yardstick process view shows how yardstick runs a test case. Below is the
+sequence graph about the test execution flow using heat context, and each
+object represents one module in yardstick:

+ :alt: Yardstick Process View
+
+A user wants to do a test with yardstick. He can use the CLI to input the
+command to start a task. "TaskCommands" will receive the command and ask
+"HeatContext" to parse the context. "HeatContext" will then ask "Model" to
+convert the model. After the model is generated, "HeatContext" will inform
+"Openstack" to deploy the heat stack by heat template. After "Openstack"
+deploys the stack, "HeatContext" will inform "Runner" to run the specific test
+case.
+
+Firstly, "Runner" would ask "TestScenario" to process the specific scenario.
+Then "TestScenario" will start to log on the openstack by ssh protocal and
+execute the test case on the specified VMs. After the script execution
+finishes, "TestScenario" will send a message to inform "Runner". When the
+testing job is done, "Runner" will inform "Dispatcher" to output the test
+result via file, influxdb or http. After the result is output, "HeatContext"
+will call "Openstack" to undeploy the heat stack. Once the stack is
+undepoyed, the whole test ends.
