             Summary: Create LOOP_FOR(duration) macro to guard testing loop from running indefinitely
                 Key: MESOS-827
                 URL: https://issues.apache.org/jira/browse/MESOS-827
             Project: Mesos
          Issue Type: Improvement
          Components: test
            Reporter: Yan Xu
            Assignee: Yan Xu
             Fix For: 0.16.0


We have tests that include loops when we are uncertain how long the expected condition will be met:

e.g.

while (future.isPending()) {
   Clock::advance(...);
   ...
}

or even simply:

AWAIT_READY(...) when the Clock is paused.

This is dangerous because if the expectation is set incorrectly the test can run forever with logs written unboundedly.
