+How it works: the benchmark task configuration file is parsed and converted
+into an internal model. The context part of the model is converted into a Heat
template and deployed into a stack. Each scenario is run using a runner, either
serially or in parallel. Each runner runs in its own subprocess executing
commands in a VM using SSH. The output of each scenario is written as json
converted into a simplified Heat template, which is used to deploy onto the
Openstack environment.

**Runner** - Logic that determines how a test scenario is run and reported, for
example the number of test iterations, input value stepping and test duration.
Predefined runner types exist for re-usage, see `Runner types`_.
-**Scenario** - Type/class of measurement for example Ping, Pktgen, (Iperf, LmBench, ...)

**SLA** - Relates to what result boundary a test case must meet to pass. For
example a latency limit, amount or ratio of lost packets and so on. Action
Use-Case View
=============
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.

finished.
