----------------------------------
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}}.
