Testing framework for Java

There is a newer version: 7.10.1

package org.testng;

/**
 * A listener used to monitor when a TestNG run starts and ends. When implementation of this
 * listener is wired into TestNG, TestNG will ensure that
 *
 * 
 *   {@link IExecutionListener#onExecutionStart()} gets invoked before TestNG proceeds with
 *       invoking any other listener.
 *   
{@link IExecutionListener#onExecutionFinish()} gets invoked at the very last (after report
 *       generation phase), before TestNG exits the JVM.
