Review Comment:
Thanks. Maybe add some (short) comment about it similar to the existing test
cases.
The "confusing" thing is, that the bounds are not "strict": for example you
use range 4 to 11, what gives the same result at 5 to 11, or 4 to 10.... (so
why is 4,11 used but not some other bound? if it's random, also ok, but should
be clarified). For testing, the interesting part is usually when "bounds" are
crossed:
For example, we could have a query range 5,9 that only returns the window
starting at 5, plus range 5,10 that returns two windows (thus we test the upper
bound from 9 and 10), plus range 6,10 that would only return the window at 10
(and thus verify the lower bound from 5 to 6). Does this make sense?
