+上文所提及的模式是指串口使用时的操作模式，不涉及硬件的工作模式的配置情况（硬件工作模式一般有轮询POLL、中断INT、DMA），因此使用时需要结合具体的硬件工作模式去配置使用。例如 发送阻塞和接收非阻塞模式 ，这个测试有很多种硬件配置，配置情况例如：DMA发送阻塞和DMA接收非阻塞，INT发送阻塞和DMA接收非阻塞，POLL发送阻塞和DMA接收非阻塞等等。因此通过排列组合后的测试场景有4*9=36种，有意义的组合方式为20种。如下表： + + +| 接收非阻塞 | 发送阻塞 | 组合 | 有意义的组合方式 | +| ---------- | -------- | ----------------- |

+需要解释的是，为什么会存在无意义的组合模式，举个例子，非阻塞模式下，肯定是不会出现POLL（轮询）方式的，因为POLL方式已经表明是阻塞方式了。 +该测试用例在测试多种组合时，需要通过更改`rtconfig.h`文件对硬件模式进行静态配置。 + +### 4.2 测试思路 + +这四个测试用例的测试思路基本一致。 + +硬件上：**短接串口的发送TX引脚和接收RX引脚，完成自发自收的回路**。 + +软件上：创建两个线程A和B，A为接收线程，B为发送线程，设置A线程优先级比B线程优先级高。发送线程发送随机长度（长度范围是 0 到 1000）的数据，接收线程接收到数据进行校验，数据正确则测试通过，默认测试100次。 + +## 5、配置 + +使用该测试用例需要在 `env` 工具的 `menuconfig` 中做相关配置，配置如下所示（使用 RT-Thread-Studio 的配置路径一致 ）： + +``` +RT-Thread Utestcases ---> + [*] RT-Thread Utestcases ---> + Utest Serial Testcase ---> + [*] Serial testcase +``` + +## 6、使用 + +\- 编译下载。 + +\- 在 MSH 中输入 `utest_run testcases.drivers.uart_rxb_txb` 运行串口接收阻塞和发送阻塞测试用例。 + +\- 在 MSH 中输入 `utest_run testcases.drivers.uart_rxb_txb` 运行串口接收阻塞和发送阻塞测试用例。 + +\- 在 MSH 中输入 `utest_run testcases.drivers.uart_rxb_txb` 运行串口接收阻塞和发送阻塞测试用例。 + +\- 在 MSH 中输入 `utest_run testcases.drivers.uart_rxb_txb` 运行串口接收阻塞和发送阻塞测试用例。 + +如果仅仅配置了 `Serial testcase` 相关的测试用例，则直接输入 `utest_run` 运行即可将上述测试用例按序测试。 + +## 7、注意事项 + +\- 需配置正确的测试用例。 + +\- 如有需要，可开启 ULOG 查看测试用例日志信息。 + +\- 需在 MSH 中输入正确的命令行。 + +\- 测试用例默认的测试数据长度范围最大为1000字节，如果接收端的缓冲区大小配置为小于1000字节时，那么在测试接收阻塞模式时，将会由于获取不了1000字节长度导致线程持续阻塞（因为测试用例是按 `recv_len` 长度去接收的，而不是按照单字节去接收的），因此建议接收端的缓冲区大小 （对应宏例如为 `BSP_UART2_RX_BUFSIZE`）设置为1024即可；当然也可按需减小测试的最大数据长度。 + +\- 该测试用例需要结合硬件具体的工作模式（POLL 、INT、DMA）进行测试，而硬件工作模式只能选择一种，因此需要在 `rtconfig.h` 中对串口相应的宏进行配置，来选择不同的工作模式去进行测试。 + diff --git a/examples/utest/testcases/drivers/serial_v2/SConscript b/examples/utest/testcases/drivers/serial_v2/SConscript new file mode 100644 index
