1570af302Sopenharmony_ci## libc-test脚本使用说明
2570af302Sopenharmony_ci
3570af302Sopenharmony_ci### 一、编译
4570af302Sopenharmony_ci
5570af302Sopenharmony_ci编译命令,仅编译libc-test测试用例
6570af302Sopenharmony_ci```
7570af302Sopenharmony_ci./build.sh --product-name rk3568 --build-target libctest
8570af302Sopenharmony_ci```
9570af302Sopenharmony_ci用例可执行文件生成的目录位于  `out/rk3568/musl/libc-test`
10570af302Sopenharmony_ci以及相关的动态库位于 `out/rk3568/musl/libc-test-lib`
11570af302Sopenharmony_ci
12570af302Sopenharmony_ci### 二、执行测试
13570af302Sopenharmony_ci
14570af302Sopenharmony_ci1. 将HDC(Windows版)工具hdc.exe加入到windows环境变量。连接上开发板,保证HDC工具可以连接。
15570af302Sopenharmony_ci
16570af302Sopenharmony_ci2. 进入musl/scripts,并根据实际环境,修改runtest_Windows.bat中测试用例生成目录完整路径(必要)
17570af302Sopenharmony_ci   ```bat
18570af302Sopenharmony_ci   @REM 本地OpenHarmony源码目录,需根据实际环境修改
19570af302Sopenharmony_ci   set LOCAL=\\wsl$\ubuntu-20.04\home\code\OpenHarmony
20570af302Sopenharmony_ci   @REM 本地编译out目录
21570af302Sopenharmony_ci   set OUTDIR=out\rk3568
22570af302Sopenharmony_ci   ```
23570af302Sopenharmony_ci
24570af302Sopenharmony_ci3. 将bat脚本复制到windows环境下使用!windows端双击运行runtest_Windows.bat,执行完毕会将详细错误结果信息REPORT返回到当前bat所在目录,并对结果进行统计生成FileList.txt(本次测试执行用例列表)与Summary.txt(统计报告),内容如下:
25570af302Sopenharmony_ci   $\color{red}{提交PR需在提交里附上对应统计报告!}$
26570af302Sopenharmony_ci   ```

46570af302Sopenharmony_ci
47570af302Sopenharmony_ci   注:此bat文件是从WSL映射目录传输文件到单板目录下,由于WSL无法直接访问windows端口,所以在WSL目录中使用可能无法传输用例。
48570af302Sopenharmony_ci
49570af302Sopenharmony_ci4. 若要单独执行测试用例,将编译结果目录下的`runtest`与需要执行的用例传输到单板
50570af302Sopenharmony_ci
51570af302Sopenharmony_ci   单板执行 `./runtest -w '' {filename}`,例如:
52570af302Sopenharmony_ci
53570af302Sopenharmony_ci   测试成功,无报错信息
54570af302Sopenharmony_ci   ```
55570af302Sopenharmony_ci   # ./runtest -w '' memmem
56570af302Sopenharmony_ci   ```
57570af302Sopenharmony_ci
58570af302Sopenharmony_ci   测试失败,提示FAIL+用例名+错误码
59570af302Sopenharmony_ci   ```
60570af302Sopenharmony_ci   # ./runtest -w '' pthread_atfork-errno-clobber
61570af302Sopenharmony_ci   ../../third_party/musl/libc-test/src/regression/pthread_atfork-errno-clobber.c:23: (pid = fork()) == -1 failed: fork succeeded despite rlimit
62570af302Sopenharmony_ci   FAIL pthread_atfork-errno-clobber [status 1]
63570af302Sopenharmony_ci   ```
64570af302Sopenharmony_ci
65570af302Sopenharmony_ci### 三、增加用例
66570af302Sopenharmony_ci
67570af302Sopenharmony_ci举例:在functional目录中新增用例new_test
68570af302Sopenharmony_ci
69570af302Sopenharmony_ci1. 在libc-test/src/functional目录下新建`new_test.c`
70570af302Sopenharmony_ci
71570af302Sopenharmony_ci2. 编辑libc-test/src/functional目录下的`test_src_functional.gni`,并在`functional_list`末尾添加`"new_test",`
72570af302Sopenharmony_ci
73570af302Sopenharmony_ci3. (可选)利用模板添加编译选项,修改`libc-test/test_template.gni`中编译选项内容或针对指定的用例添加,例如:
74570af302Sopenharmony_ci   ```
75570af302Sopenharmony_ci   if (target_name == "tls_init") {
76570af302Sopenharmony_ci     cflags += [ "-Wno-literal-range" ]
77570af302Sopenharmony_ci     ldflags += [ "-Wl,-rpath=./" ]
78570af302Sopenharmony_ci     libs += [ "//${root_out_dir}/${test_lib_dir}/libtls_init_dso.so" ]
79570af302Sopenharmony_ci   }
80570af302Sopenharmony_ci   ```
81570af302Sopenharmony_ci
82570af302Sopenharmony_ci3. 执行步骤一(编译)中的编译命令,即可生成对应可执行文件。
