检查新接口是否包含枚举的JUnit

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

public class InterfaceTest {
    
    @Test
    public void testEnumInInterface() {
        // 假设接口名为NewInterface
        Class<?> newInterface = NewInterface.class;
        
        // 判断接口是否包含枚举
        boolean containsEnum = false;
        for (Class<?> nestedClass : newInterface.getDeclaredClasses()) {
            if (nestedClass.isEnum()) {
                containsEnum = true;
                break;
            }
        }
        
        // 断言接口是否包含枚举
        assertTrue("接口应包含枚举", containsEnum);
    }
