getTimeRangeTracker

protected TimeRangeTracker getTimeRangeTracker()

Overrides:

getTimeRangeTracker in class TestSimpleTimeRangeTracker

getTimeRangeTracker

protected TimeRangeTracker getTimeRangeTracker(long min,
                                               long max)

Overrides:

getTimeRangeTracker in class TestSimpleTimeRangeTracker

testArriveAtRightAnswer

public void testArriveAtRightAnswer()
                             throws InterruptedException

Run a bunch of threads against a single TimeRangeTracker and ensure we arrive at right range. Here we do ten threads each incrementing over 100k at an offset of the thread index; max is 10 * 10k and min is 0.

Throws:

InterruptedException

testConcurrentIncludeTimestampCorrectness

public void testConcurrentIncludeTimestampCorrectness()

Run a bunch of threads against a single TimeRangeTracker and ensure we arrive at right range. The data chosen is going to ensure that there are lots collisions, i.e, some other threads may already update the value while one tries to update min/max value.
