How do you test code that uses virtual threads (Project Loom)?

Testing code that utilizes virtual threads in Java's Project Loom allows for easier concurrent programming. This guide provides a straightforward example demonstrating how to write tests for virtual threads effectively.

        import org.junit.jupiter.api.Test;
        import static org.junit.jupiter.api.Assertions.assertEquals;
        
        public class VirtualThreadTest {
            @Test
            public void testVirtualThread() {
                // Create a virtual thread
                Thread virtualThread = Thread.ofVirtual().start(() -> {
                    // Simulate some work in the virtual thread
                    return 42;
                });
                
                // Wait for the result and assert
                assertEquals(42, virtualThread.join());
            }
        }
