[md]# OpenHarmony 使用、开发 FuzzTest 指南

## 编译FuzzTest

```bash
./build.sh --build-target GetAppStatsMahFuzzTest --product-name rk3568 --gn-args battery_statistics_feature_coverage=true
```

> --build-target：对应的fuzztest，本次选的是base/powermgr/battery_statistics/test/fuzztest/getappstatsmah_fuzzer/BUILD.gn里的测试用例；
>
> --product-name：对应测试设备，rk3568（Dayu200）
>
> --gn-args：对应的编译参数，用于打开code_coverage的编译开关，详见coverage_flags的配置项（base/powermgr/battery_statistics/utils/BUILD.gn）

* 编译结束后可在 查看FuzzTest：

```bash
#find  out/rk3568/tests/fuzztest/ -name GetAppStatsMahFuzzTest
out/rk3568/tests/fuzztest/battery_statistics/battery_statistics/GetAppStatsMahFuzzTest

```

* 编译结束后可验证CodeCoverage：

```bash

## 部署测试环境（windows)

### 1. 准备目录

* 在d盘建立test目录，里面下载developer_test和xdevice的代码

```bash
git clone https://gitcode.com/openharmony/testfwk_developer_test.git
git clone https://gitcode.com/openharmony/testfwk_xdevice.git
```

> testfwk_developer_test：是测试框架代码，主要支持unittest和fuzztest；
>
> testfwk_xdevice：是测试驱动，用来连接测试设备，运行测试用例和记录日志，生成报告；

### 2. 准备环境

* **从编译结果里拷贝fuzztest**（fuzztest的位于编译输出路径下out/rk3568/tests/fuzztest）到test目录内
* **从编译结果里拷贝res**（res的位于编译输出路径下out/rk3568/tests/res）到test目录内
* 从编译结果拷贝gen

![testsdir.png](https://forums-obs.openharmony.c ... wels6toxenxnou6.png "testsdir.png")

*注意：如果少拷贝这两个文件都会出现测试时候不能运行的情况，如下：**unavailable: 1***

```

* **修改配置文件**，developer_test\config\user_config.xml里的配置项

```
修改testcase路径，注意，必须用此路径，至少目前如此！
<!-- configure test cases path -->
  <test_cases>
    <dir>D:\test\tests</dir>
  </test_cases>
  
修改测试覆盖率的输出路径
<!-- reserved field, configure output path for coverage -->
  <coverage>
    <outpath>D:\test\out</outpath>
  </coverage>
```

### 3. 运行测试

* 进入test\developer_test，运行start.bat

```
D:\test\developer_test>start.bat
start time is:
10:52

* 结束后检查gcda输出（如果用coverage编译选项输出的二进制，无论是否是“-cov coverage” 运行的都能看到输出，目前社区版本“-cov coverage” 不支持linux下运行

```shell
C:\Users\Administrator>hdc -t 450100445634303332016bde0a2eba00 shell find /home/wshi/ -name '*.gcda'
/home/wshi/ohos/60release/src/out/rk3568/obj/base/powermgr/battery_statistics/frameworks/native/src/batterystats_stub/battery_stats_info.gcda

```

**注意**：这就是模拟编译环境生成的目标路径

### 4. 运行分析工具

* 执行命令：gen_gcovr.py --gcvr （对测试结果进行覆盖率分析）
  * 运行路径：developer_test\local_coverage/resident_service/gen_gcovr.py
  * 执行参数：-gcvr，对测试结果进行覆盖率检查
  * 执行依赖：
    1. 需要连接有测试结果的开发板；
    2. 需要在developer_test目录里创建outobjs目录：里面保存编译出来的.gcno文件，可以直接把out/rk3568/obj文件夹拷贝至此
    3. 需要在developer_test目录里创建outsrc目录：里面保存源文件或者gen出来的hdf驱动相关的文件（out/rk3568/gen）

```
PS D:\test\developer_test> python local_coverage/resident_service/gen_gcovr.py --gcvr
