How do you test code that uses StampedLock?

Testing code that utilizes StampedLock in Java involves understanding the synchronization and lock mechanism it provides. StampedLock is a flexible locking mechanism introduced in Java 8 that allows for optimistic read locks, write locks, and read locks. Below is a simple example demonstrating how to use StampedLock and how to write tests for it.

        // Example of using StampedLock
        import java.util.concurrent.locks.StampedLock;

        public class StampedLockExample {
            private final StampedLock lock = new StampedLock();
            private int value = 0;

            public void increment() {
                long stamp = lock.writeLock();
                try {
                    value++;
                } finally {
                    lock.unlockWrite(stamp);
                }
            }

            public int getValue() {
                long stamp = lock.readLock();
                try {
                    return value;
                } finally {
                    lock.unlockRead(stamp);
                }
            }
        }

        // Example test for StampedLock
        import org.junit.Test;
        import static org.junit.Assert.assertEquals;

        public class StampedLockTest {

            @Test
            public void testIncrementAndGetValue() {
                StampedLockExample example = new StampedLockExample();
                example.increment();
                assertEquals(1, example.getValue());
            }
        }
