Did you mean that if the "task" in question in the test reaches a terminal
state? This shouldn't happen otherwise if the "used" resources on the agent did
not change (task is active)

> 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.
> One way to avoid this would be to pause the clock by default in tests
> (MESOS-4101). That would be a quite involved change, however.
> 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}}.
