+# RT-Thread 测试用例集合
+
+## 简介
+
+为了保证某一部分代码的质量，通常可以通过编写测试用例的方式，验证此代码的功能。为了保证 RT-Thread 相关仓库的代码质量，我们基于 utest 框架搭建了一套简易的自动化测试环境。有兴趣，有精力的小伙伴可以利用这套机制完善自己的代码检查。如果有意愿让社区上更多的小伙伴收益，也可以在提交代码的时候，把对应的测试用例也提交上来。
+
+## 目录结构
+
+| 目录      | 用途                                                         |
+| --------- | ------------------------------------------------------------ |
+| configs   | 配置文件集合（每一个目录代表一种功能集合，如：kernel,net等） |
+| testcases | 测试用例源代码                                               |
+
+## 如何贡献
+
+### 1. 编写测试用例
+
+参考已有的测试用例在 [examples\utest\testcases](./testcases) 目录下添加自己的测试用例。测试用例的编写方法参考文档中心《utest 测试框架》章节。
+
+### 2. 本地测试
+
+1. 在 `bsp\qemu-vexpress-a9` 目录下打开 `menuconfig`，使能对应的测试用例，如下：
+
+```
+RT-Thread Utestcases  --->
+  [*] RT-Thread Utestcases
+        Utest Self Testcase  --->
+          [*] Pass test
+```
+
+2. 保存并退出，输入 scons 编译当前 bsp。
+
+3. 输入 .\qemu.bat 运行当前 bsp，在 msh 环境下执行 utest_run 命令，验证代码运行是否正常。
+
+```
+msh />utest_run
+[I/utest] [==========] [ utest    ] loop 1/1
+[I/utest] [==========] [ utest    ] started
+[I/utest] [----------] [ testcase ] (testcases.utest.pass_tc) started
+[D/utest] [    OK    ] [ unit     ] (test_assert_pass:16) is passed
+[D/utest] [    OK    ] [ unit     ] (test_assert_pass:17) is passed
+[D/utest] [    OK    ] [ unit     ] (test_assert_pass:19) is passed
+[D/utest] [    OK    ] [ unit     ] (test_assert_pass:20) is passed
+[D/utest] [    OK    ] [ unit     ] (test_assert_pass:22) is passed
+[D/utest] [    OK    ] [ unit     ] (test_assert_pass:23) is passed
+[D/utest] [    OK    ] [ unit     ] (test_assert_pass:25) is passed
+[D/utest] [    OK    ] [ unit     ] (test_assert_pass:26) is passed
+[D/utest] [    OK    ] [ unit     ] (test_assert_pass:28) is passed
+[D/utest] [    OK    ] [ unit     ] (test_assert_pass:29) is passed
+[I/utest] [  PASSED  ] [ result   ] testcase (testcases.utest.pass_tc)
+[I/utest] [----------] [ testcase ] (testcases.utest.pass_tc) finished
+[I/utest] [==========] [ utest    ] finished
+```
+
+### 3. 提交
+
+1. 如果是对已有测试集合的完善，需要把添加的测试用例的配置项添加到对应测试集合的配置文件里，如：[examples\utest\configs\utest_self\config.h](./configs/utest_self/config.h)。
+
+```
+/* RT-Thread Utestcases */
+
+#define RT_USING_UTESTCASES
+
+/* Utest Self Testcase */
+
+#define UTEST_SELF_PASS_TC
+
+/* xxx Testcase */
+#define UTEST_XXX_TC
+```
+
+2. 如果要添加新的测试集合，需要参考已有的测试集合，在 [examples\utest\configs](./configs) 目录下添加新的测试集合配置项。并更新 [.github\workflows\action_utest.yml](../../.github/workflows/action_utest.yml) 内的测试集合。
+
+```

+- {UTEST: "components/utest", RTT_BSP: "bsp/qemu-vexpress-a9", QEMU_ARCH: "vexpress-a9", CONFIG_FILE: "examples/utest/configs/utest_self/config.h"}
+```
+
+3. 向 RT-Thread 主仓库提交合并请求。
