# RT-Thread 测试用例集合
## 简介
2021-05-11 09:22:49 +08:00
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kernel,net等 |
| testcases | 测试用例源代码 |
## 如何贡献
### 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。
2021-05-10 20:34:33 +08:00
### 2. 本地测试
2021-05-11 09:22:49 +08:00
1.`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
[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,以及对应的依赖项添加到对应测试集合的配置文件里,如:[examples\utest\configs\kernel\mem.conf](./configs/kernel/mem.conf)。
2021-05-10 20:34:33 +08:00
```
CONFIG_UTEST_MEMHEAP_TC=y
2021-05-10 20:34:33 +08:00
# dependencies
CONFIG_RT_USING_MEMHEAP=y
2021-05-10 20:34:33 +08:00
```
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/mem", RTT_BSP: "bsp/qemu-vexpress-a9", QEMU_ARCH: "arm", QEMU_MACHINE: "vexpress-a9", CONFIG_FILE: "kernel/mem.conf", SD_FILE: "sd.bin"}
- {UTEST: "components/utest", RTT_BSP: "bsp/qemu-vexpress-a9", QEMU_ARCH: "arm", QEMU_MACHINE: "vexpress-a9", CONFIG_FILE: "utest_self/self.conf", SD_FILE: "sd.bin"}
2021-05-10 20:34:33 +08:00
```
3. 向 RT-Thread 主仓库提交合并请求。
