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。

### 1. 编写测试用例
|
|
|
|
|

|
2021-05-11 18:43:05 +08:00
|
|
|
|
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
|
|
|
|
|
|
|
2021-05-11 09:22:49 +08:00
|
|
|
|
1. 在 `bsp\qemu-vexpress-a9` 目录下打开 `menuconfig`，使能对应的测试用例，如下：
|
2021-05-10 20:34:33 +08:00
|
|
|
|
|
|
|
|
|
|
```
|
|
|
|
|
|
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
|
|
|
|

|
|
|
|
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)。
|
2021-05-10 20:34:33 +08:00
|
|
|
|
|
|
|
|
|
|
```
|
|
|
|
|
|
/* RT-Thread Utestcases */
|
|
|
|
|
|
|
|
|
|
|
|
#define RT_USING_UTESTCASES
|
|
|
|
|
|
|
|
|
|
|
|
/* Utest Self Testcase */
|
|
|
|
|
|
|
|
|
|
|
|
#define UTEST_SELF_PASS_TC
|
|
|
|
|
|
|
|
|
|
|
|
/* xxx Testcase */
|
|
|
|
|
|
#define UTEST_XXX_TC
|
|
|
|
|
|
```
|
|
|
|
|
|
|
2021-05-11 18:43:05 +08:00
|
|
|
|
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。
|
2021-05-10 20:34:33 +08:00
|
|
|
|
|
|
|
|
|
|
```
|
|
|
|
|
|
- {UTEST: "kernel/ipc", RTT_BSP: "bsp/qemu-vexpress-a9", QEMU_ARCH: "vexpress-a9", CONFIG_FILE: "examples/utest/configs/utest_self/config.h"}
|
|
|
|
|
|
- {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。
