以下是一个简单的测试用例，测试了函数的返回值和一些输入参数的有效性：

#include <stdio.h>
#include <assert.h>
#include "your_header_file.h"

int main() {
    // 初始化一些参数
    LPP_SDDM_ENV sddmEnv;
    SDDM_PTABLE pTable = NULL;
    SDDM_SAFEHANDLE hObj = NULL;
    VOIDPTR dataPtr = NULL;
    WORD32 keyLen = 0;
    WORD32 totalLen = 0;
    WORD32 op = 0;

    // 测试传入 NULL 参数的情况
    assert(packetShadowNotifyCallback(NULL, pTable, hObj, dataPtr, keyLen, totalLen, op) == ROSNG_PARAM_ERROR);
    assert(packetShadowNotifyCallback(&sddmEnv, NULL, hObj, dataPtr, keyLen, totalLen, op) == ROSNG_PARAM_ERROR);
    assert(packetShadowNotifyCallback(&sddmEnv, pTable, NULL, dataPtr, keyLen, totalLen, op) == ROSNG_PARAM_ERROR);
    assert(packetShadowNotifyCallback(&sddmEnv, pTable, hObj, NULL, keyLen, totalLen, op) == ROSNG_PARAM_ERROR);

    // 测试传入 0 参数的情况
    assert(packetShadowNotifyCallback(&sddmEnv, pTable, hObj, dataPtr, 0, totalLen, op) == ROSNG_PARAM_ERROR);
    assert(packetShadowNotifyCallback(&sddmEnv, pTable, hObj, dataPtr, keyLen, 0, op) == ROSNG_PARAM_ERROR);
    assert(packetShadowNotifyCallback(&sddmEnv, pTable, hObj, dataPtr, 0, 0, op) == ROSNG_PARAM_ERROR);

    // TODO: 测试其他情况，例如 SDDM_NOTIFY_UPDATE 和 SDDM_NOTIFY_DELETE

    printf("All tests passed!\n");
    return 0;
}

需要注意的是，这个测试用例只覆盖了一些基本情况，你可能需要测试更多的情况来确保你的代码正确无误。
