Class T_MultiThreadedIterations

java.lang.Object

org.apache.derbyTesting.unitTests.harness.T_Generic

org.apache.derbyTesting.unitTests.harness.T_MultiIterations

org.apache.derbyTesting.unitTests.harness.T_MultiThreadedIterations

All Implemented Interfaces:

java.lang.Runnable, org.apache.derby.iapi.services.monitor.ModuleControl, UnitTest

Direct Known Subclasses:

T_DaemonService, T_FileSystemData, T_RawStoreFactory, T_StreamFile

public abstract class T_MultiThreadedIterations
extends T_MultiIterations
implements java.lang.Runnable

Abstract class which executes T_MultiIterations. This allows multiple threads running T_MultiIterations. This allows the setup to be performed once, and then the test itself to be run with multiple threads for a number of iterations. The number of threads and iterations are set by the property derby.unittests.numThreads and derby.unittests.iterations and default to 1.

Statistics are provided about each iteration in the error log. The statistics are time for each iteration, used and total memory changes per iteration.
