-# DIM 测试文档
-
-## 1 前置条件
-
-**OS版本支持**：openEuler 23.09以上版本；
-
-**内核版本支持**：当前支持openEuler kernel 5.10/6.4版本；
-
-**注意**：DIM包含内核组件，相关步骤需要以管理员（root）权限运行。
-
-## 2 使用openEuler源进行安装
-```
-yum install dim dim_tools make gcc
-```
-
-## 3 执行测试用例
-```
-cd dim/test/
-sh test/test_dim_core.sh
-sh test/test_monitor_core.sh
-```
-
-**注意**：全量度量功能默认关闭，如有需要，请将用例添加到对应的case_list中
