             Summary: Switch to parallel test execution
                 Key: TOREE-269
                 URL: https://issues.apache.org/jira/browse/TOREE-269
             Project: TOREE
          Issue Type: Improvement
            Reporter: Chip Senkbeil
            Assignee: Chip Senkbeil


I've used this in other projects and it speeds up tests by a factor of 10 or more. You bring in {code}ParallelTestExecution{code} as a trait for all of your test classes. Sbt will run tests in parallel automatically once that is added.

_ ParallelTestExecution_ in turn brings in _OneInstancePerTest_, which makes ScalaTest specs act like JUnit where a new instance of the class is created per test so any val is created fresh per test. As long as a spec doesn't depend on any global state, we can add _ ParallelTestExecution_ and be done with it.

Obviously, system tests won't do this, although the kernel _should_ be able to handle concurrent requests by blocking.
