需要真实Ascend设备支持，无法在虚拟环境进行
在上一节中，成功制作了Mindspore的Add算子，具体可以查看MindStudio制作MindSpore TBE算子（一）算子制作，
并在MindStudio制作MindSpore TBE算子（二）算子测试中介绍了算子的UT测试，本节内容将详细介绍算子ST测试，即算子的实现验证。
建议参考以下内容一起食用：
算子代码实现
MindSpore框架TBE算子开发全流程

制作Mindspore的TBE流程中用于测试的是test_xxx_impl.py和xxx_case_timestation.json文件。

ST测试

ST测试（System Testing，系统测试） 目标是确保算子不仅在孤立的环境中能够正确运行，还能与其他组件（如数据管道、模型训练框架等）协同工作，并满足性能和功能要求。与单元测试（UT）不同，ST测试关注的是系统级的功能、性能、可靠性和用户体验。

1. 右击对应的算子工程文件，选择New Case中的ST case；![在这里插入图片描述]
   

2. 选择对应的算子，点击OK
   

3. 编写测试样例信息
   

点击执行后，可能出现报错：

bug 1：ST测试无法解析正确Python环境

报错信息显示，缺乏MindSpore安装包，这里也是和之前类似的问题，应该使用mindspore环境进行调试开发，但是这里使用的是base环境。
这是因为MindStudio是在conda的base环境中启动的，这里需要重新在conda mindspore环境中其中mindstudio。

conda activate mindstudio
bash MindStudio.sh

bug 2：缺乏Ascend环境，无法执行

继续执行后出现新的报错，

context.set_context(mode=context.GRAPH_MODE, device_target="Ascend", device_id=0)

这里我的执行环境是虚拟机，没有ascend设置，执行设置设置到Ascend中，导致出现此问题。因此，尝试去解决需要修改代码。

(mindspore) science@science-2204:~/MindstudioProjects$ find . -name test_addcustom.py
./Add_custom/testcases/st/out/addcustom/src/test_addcustom.py

如果去修改test_addcustom.py，发现是无法解决此问题的，每次重新点击运行后依然会覆盖此文件。

context.set_context(mode=context.GRAPH_MODE, device_target="CPU", device_id=0)

后查阅资料，发现只能在真实环境中验证算子功能正确性，奈何现有MindStudio最新版本砍掉远程连接功能，无法链接云服务器，只能在此戛然而止，欠各位看官一篇完整报告，后期补上。
