The process of paralellizing JBossCache testsuite is underway and here are some guidelines to help write new tests which could be ran using parallel TestNG testsuite runner. 1. Declare the test class as sequential using @Test annotation or (preferrably) write the test class thread safe so the test methods could be ran simultaneously. Example of @Test annotation to be used in a non thread-safe test class: @Test(groups = {"functional", "transaction", "optimistic"}, sequential = true) 2. In the case the test class needs replicated cache use UnitTestCacheFactory class to instantiate the cache. The UnitTestCacheFactory will ensure that the cache will use different mcast_addr and mcast_port than other tests running in different threads. Also, create the cache configuration before invoking createCache factory method and pass the configuration as an argument. Example: Configuration c = new Configuration(); c .setTransactionManagerLookupClass (DummyTransactionManagerLookup.class.getName()); c.setNodeLockingScheme(Configuration.NodeLockingScheme.OPTIMISTIC); c.setCacheMode(Configuration.CacheMode.REPL_SYNC); Cache cache = new UnitTestCacheFactory<Object, Object>().createCache(c, false)); 3. At the end of the test (or test method if not sequential), all the cache instances must be destroyed. The cleanUp method of the UnitTestCacheFactory could be used for this purpose. Note that the method relies on the fact that it is executed in the same thread as the thread in which the cache(s) were created. 4. That's it!
