Method Detail getTest1Cache protected JCache getTest1Cache() throws CacheException(Code) Gets the sample cache 1 setUp protected void setUp() throws Exception(Code) setup test tearDown protected void tearDown() throws Exception(Code) teardown limits to what we can do here under jsr107 testAPIObjectCompatibility public void testAPIObjectCompatibility() throws CacheException(Code) Does the Object API work? jsr107 is an object API testAPISerializableCompatibility public void testAPISerializableCompatibility() throws CacheException(Code) Does the Serializable API work? testCacheExceptionHandler public void testCacheExceptionHandler()(Code) Test exception handling from JCache testCacheStatistics public void testCacheStatistics() throws Exception(Code) Test cache statistics, including get. Reconcile CacheEntry stats with cache stats and make sure they agree testClear public void testClear()(Code) Tests clear() testContainsKey public void testContainsKey() throws Exception(Code) Test containsKey testContainsValue public void testContainsValue() throws Exception(Code) Test containsValue testEhcacheConstructor public void testEhcacheConstructor() throws Exception(Code) Create a JCache from an inactive Ehcache and try adding to CacheManager. Check that getting JCache, Ehcache and Cache all make sense. testElementStatistics public void testElementStatistics() throws Exception(Code) Test element statistics, including get and getQuiet eternal="false" timeToIdleSeconds="5" timeToLiveSeconds="10" overflowToDisk="true" jsr107 has no put quiet testEvict public void testEvict() throws Exception(Code) Test isEmpty testExpiryBasedOnTimeToIdle public void testExpiryBasedOnTimeToIdle() throws Exception(Code) Test expiry based on time to idle. testExpiryBasedOnTimeToLive public void testExpiryBasedOnTimeToLive() throws Exception(Code) Test expiry based on time to live testExpiryBasedOnTimeToLiveTTL public void testExpiryBasedOnTimeToLiveTTL() throws Exception(Code) Test expiry based on time to live where the TTL is set in the put testExpiryBasedOnTimeToLiveUsingPeek public void testExpiryBasedOnTimeToLiveUsingPeek() throws Exception(Code) Test expiry based on time to live. This test uses peek, which behaves the same as get testExpiryBasedOnTimeToLiveWhenNoIdle public void testExpiryBasedOnTimeToLiveWhenNoIdle() throws Exception(Code) Test expiry based on time to live testGet public void testGet() throws Exception(Code) Test the get method. testGetAll public void testGetAll() throws InterruptedException, ExecutionException, CacheException(Code) Tests the getAll Public API method testGetKeysAfterExpiry public void testGetKeysAfterExpiry() throws Exception(Code) Test getKeys after expiry Makes sure that if an element is expired, its key should also be expired testGetKeysPerformance public void testGetKeysPerformance() throws Exception(Code) Checks the expense of checking for duplicates JSR107 has only one keyset command. It returns a Set rather than a list, so duplicates are automatically handled. 31ms for 2000 keys, half in memory and half on disk testGetSizeAfterExpiry public void testGetSizeAfterExpiry() throws Exception(Code) Expire elements and verify size is correct. testGetValues public void testGetValues() throws Exception(Code) Test the get values method. testIsEmpty public void testIsEmpty() throws Exception(Code) Test isEmpty testKeySet public void testKeySet()(Code) Test the keyset method testLoad public void testLoad() throws InterruptedException, ExecutionException, CacheException(Code) Tests the public API load method with a single item testLoadAll public void testLoadAll() throws InterruptedException, ExecutionException, CacheException(Code) Tests the loadAll Public API method testLoadWithDynamicLoaderInjection public void testLoadWithDynamicLoaderInjection() throws InterruptedException, ExecutionException, CacheException(Code) Tests that the setLoader method allows the loader to be changed. The load is async so timing is important. testLoaderName public void testLoaderName() throws Exception(Code) Test the loader name method. testNoIdleOrExpiryBasedOnTimeToLiveForEternal public void testNoIdleOrExpiryBasedOnTimeToLiveForEternal() throws Exception(Code) Test expiry based on time to live testNoOverflowToDisk public void testNoOverflowToDisk() throws Exception(Code) Test overflow to disk = false testNonSerializableElement public void testNonSerializableElement() throws Exception(Code) Tests using elements with null values. They should work as normal. throws:   Exception - testNullCacheEntry public void testNullCacheEntry()(Code) Check getting a cache entry where it does not exist testNullTreatment public void testNullTreatment() throws Exception(Code) Tests putting nulls throws correct exception throws:   Exception - testProportionMemoryAndDiskPerformance public void testProportionMemoryAndDiskPerformance() throws Exception(Code) Performance tests for a range of Memory Store - Disk Store combinations. This demonstrates that a memory only store is approximately an order of magnitude faster than a disk only store. It also shows that double the performance of a Disk Only store can be obtained with a maximum memory size of only 1. Accordingly a Cache created without a maximum memory size of less than 1 will issue a warning. Threading changes were made in v1.41 of DiskStore. The before and after numbers are shown. testPutAll public void testPutAll()(Code) Tests putAll testReadWriteThreads public void testReadWriteThreads() throws Exception(Code) Multi-thread read-write test with lots of threads Just use MemoryStore to put max stress on cache Values that work: The get here will often load data, so it does not give raw cache performance. See the similar test in CacheTest for that. testSizeMultipleCallsWithPutAndRemove public void testSizeMultipleCallsWithPutAndRemove() throws Exception(Code) Test size after multiple calls, with put and remove testSizeWithPutAndRemove public void testSizeWithPutAndRemove() throws Exception(Code) Test size with put and remove. It checks that size makes sense, and also that getKeys.size() matches getSize() testSizes public void testSizes() throws Exception(Code) Tests cache, memory store and disk store sizes from config jsr107 does not breakdowns of store sizes. testSpoolThreadHandlesThreadKiller public void testSpoolThreadHandlesThreadKiller() throws Exception(Code) Tests what happens when an Element throws an Error on serialization. This mimics what a nasty error like OutOfMemoryError could do. Before a change to the SpoolAndExpiryThread to handle this situation this test failed and generated the following log message. Jun 28, 2006 7:17:16 PM net.sf.ehcache.store.DiskStore put SEVERE: testThreadKillerCache: Elements cannot be written to disk store because the spool thread has died. throws:   Exception - testToString public void testToString() throws CacheException(Code) Tests that the toString() method works.
