Steve Loughran commented on SLIDER-309:
---------------------------------------

This could be tested with the chaos monkey

# set it up with a 100% failure rate
# and a poll frequency to ensure that its failure rate is just below the threshold
# expect it to run for a while
# flex to a lower threshold/larger window
# expect app failure

> add functional tests of sliding-window  failure handling

> There's some testing of the sliding window logic at the mock level, and of configurable thresholds in the HBase provider.
> But not in the agent. We need
> # functional test to verify that a failure rate less than (threshold/window-size) is acceptable.
> # test to verify window is reset on AM failure (manually verified)
> # test to verify that a cluster flex resets the values and allows the threshold to be changed
