 * This interface can be implemented by tests that want to know if they are being run concurrently. It provides
 * lifecycle notification events to tell the test implementation when test threads are being created and destroyed. This
 * can assist tests in creating and destroying resources that exist over the life of a test thread. A single test thread
 * can excute the same test many times, and often it is convenient to keep resources, for example network connections,
 * open over many test calls.
