Method Detail

assertInRange

public static void assertInRange(long start,
                                 long end,
                                 long actual)

Asserts that two longs are equal concerning a delta.

testHitMissCount

public void testHitMissCount()
                      throws com.gemstone.gemfire.cache.CacheException

Tests that the hit count and miss count are updated properly for a local region and its entries.

Throws:

com.gemstone.gemfire.cache.CacheException

testTimeStats

public void testTimeStats()
                   throws com.gemstone.gemfire.cache.CacheException,
                          InterruptedException

Tests that the last access time and last modified time are update appropriately for a local region and its entries. It also validates that the last modification and last access times are propagated to parent regions.

Throws:

com.gemstone.gemfire.cache.CacheException

InterruptedException

testDistributedStats

public void testDistributedStats()

Tests that distributed operations update the last modified time, but not the last accessed time. It also validates that distributed operations do not affect the hit and miss counts in remote caches.

testDisabledStatistics

public void testDisabledStatistics()
                            throws com.gemstone.gemfire.cache.CacheException

Tests that an attempt to get statistics when they are disabled results in a StatisticsDisabledException.

Throws:

com.gemstone.gemfire.cache.CacheException
