当集合比较失败时，在测试输出中打印任意属性值

import org.junit.Test;
import static org.junit.Assert.assertEquals;

public class CollectionComparisonTest {
    
    @Test
    public void testCollectionComparison() {
        // 假设我们要比较的是一个包含对象的集合
        List<CustomObject> expectedList = new ArrayList<>();
        List<CustomObject> actualList = new ArrayList<>();
        
        // 向集合中添加对象...
        
        try {
            // 使用断言方法进行集合比较
            assertEquals(expectedList, actualList);
        } catch (AssertionError e) {
            // 捕获比较失败的异常
            System.out.println("集合比较失败！");

            // 在此处打印任意属性值
            for (int i = 0; i < expectedList.size(); i++) {
                CustomObject expected = expectedList.get(i);
                CustomObject actual = actualList.get(i);
                
                System.out.println("对象属性值：");
                System.out.println("Expected: " + expected.getProperty());
                System.out.println("Actual: " + actual.getProperty());
            }
        }
    }
}
