在Java中单元测试线程安全的任何令人满意的方法？

import java.util.concurrent.CountDownLatch;
import java.util.concurrent.ExecutorService;
import java.util.concurrent.Executors;

public class ThreadSafeTest {
    private int count;

    public void increment() {
        count++;
    }

    public int getCount() {
        return count;
    }

    public static void main(String[] args) throws InterruptedException {
        ThreadSafeTest test = new ThreadSafeTest();
        ExecutorService executor = Executors.newFixedThreadPool(10);
        CountDownLatch latch = new CountDownLatch(10);

        for (int i = 0; i < 10; i++) {
            executor.submit(() -> {
                for (int j = 0; j < 1000; j++) {
                    test.increment();
                }
                latch.countDown();
            });
        }

        latch.await();
        executor.shutdown();

        System.out.println("Count: " + test.getCount());
    }
}
