Karan Singhal commented on PHOENIX-2592:
----------------------------------------
[~giacomotaylor] Was just curios to know why this is happening so just spent
little time to find out the issue. The reason it's happening is because the
function (randomDataGenerator.nextLong (minDt.getMillis(), maxDt.getMillis() )
) which is being used to generate random date between two limits generates
data with endpoints included. And the assertion in RuleGenratorTest class is
assertDateBetween which checks the date generated is exactly between limits and
it fails sometimes because date generated is sometimes same as limits as in the
above stack-trace we can see.
I have a very simple fix for this we just have to add 1 unit to lower limit and
subtract 1 from upper limit when we pass the limits to function, this will
make sure the data generated is exactly between limits.
This test is there from starting so don't know why this issue didn't happen
before, may be probability is really very low so never occurred such
frequently. I never got this error in so many builds. But for sure this is a
bug and needs to be fixed.
Let me know if I can go ahead and submit patch for this.
