Restraint is designed to execute tasks. These tasks can be tests which report results or simply code that you want to automate. Which tasks to execute is determined by a job¹. The job also describes where to retrieve the tasks from and what parameters to pass in. These tasks can report multiple PASS, FAIL, WARN results along with an optional score. Tasks also have the ability to report log files. Each task can have metadata describing dependencies and max run time for example. Execution and reporting can be further enhanced with plugins.

Restraint can be used with Beaker² since it talks beaker's Harness API³ for reporting results. But it can also be used stand alone.
