             Summary: Increase default allocation_interval for tests
                 Key: MESOS-6825
                 URL: https://issues.apache.org/jira/browse/MESOS-6825
             Project: Mesos
          Issue Type: Improvement
          Components: tests
            Reporter: Neil Conway


The default {{allocation_interval}} is 1 second. This means that if the host running the tests is slow, a test case might receive a resource offer that it doesn't receive when running on a faster host. We could workaround this by explicitly using {{WillRepeatedly(Return())}, but that is a bit kludgy and obscures the intent of the test.

Instead, we could consider raising the default {{allocation_interval}} to a large value, such as 1 minute or longer. This would significantly reduce the chance of host performance causing test flakiness. Moreover, it would help to highlight tests that rely on real-time batch allocations for correctness: generally tests should avoid doing this (because it causes test slowness). They should instead pause the clock and then advance it by {{allocation_interval}}.
