1 框架简介

1.1 L0框架简介

L0设备使用的测试框架是hctest,其代码位于test/xts/tools/lite/hctest目录下。此框架支持使用C语言编写测试用例,是在开源测试框架unity的基础上进行增强和适配。

2 用例编写

2.1 目录规范

2.1.1 目录规划

L0的测试用例存放在各子系统部件模块的根目录下,例如utils/native/lite/test。

2.1.2 目录结构

部件根目录
    ├── test
    │   ├── kv_store_hal
    │   │   ├── BUILD.gn
    │   │   ├── Test.tmpl
    │   │   └── src
    │   │       └── kvstore_func_test.c
    │   └── kv_store_posix
    │       ├── BUILD.gn
    │       ├── Test.json
    │       └── src
    │           └── KvStoreTest.cpp

备注:hal归档L0自动化用例,posix归档L1自动化用例

2.2 用例编写

2.2.1 引用测试框架

#include “hctest.h”

2.2.2 定义测试信息

使用宏定义LITE_TEST_SUIT定义子系统,模块,测试套件名称

/**
 * @tc.desc      : register a test suite, this suite is used to test basic flow and interface dependency
 * @param        : subsystem name is utils
 * @param        : module name is kvStore
 * @param        : test suit name is KvStoreFuncTestSuite
 */
LITE_TEST_SUIT(utils, kvStore, KvStoreFuncTestSuite);

2.2.3 定义Setup和TearDown

1、命名方式:测试套件名称+Setup,测试套件名称+TearDown;2、Setup和TearDown函数必须存在,函数体可以为空

/**
 * @tc.setup     : setup for all testcases
 * @return       : setup result, TRUE is success, FALSE is fail
 */
static BOOL KvStoreFuncTestSuiteSetUp(void)
{
   return TRUE;
}

/**
 * @tc.teardown  : teardown for all testcases
 * @return       : teardown result, TRUE is success, FALSE is fail
 */
static BOOL KvStoreFuncTestSuiteTearDown(void)
{
   return TRUE;
}

2.2.4 编写测试用例

包括三个参数:测试套件名称,测试用例名称,用例级别

/**
 * @tc.number    : SUB_UTILS_KV_STORE_0100
 * @tc.name      : UtilsSetValue parameter legal test
 * @tc.desc      : [C- SOFTWARE -0200]
 */
LITE_TEST_CASE(KvStoreFuncTestSuite, KvStoreSetValue001, Function | MediumTest | Level1)
{
   char key[] = "rw.sys.version";
   char value[] = "Hello world !";
   int ret = UtilsSetValue(key, value);
   TEST_ASSERT_EQUAL_INT(0, ret);

   ret = UtilsDeleteValue(key);
   TEST_ASSERT_EQUAL_INT(0, ret);
};

2.2.5 注册测试套件

RUN_TEST_SUITE(KvStoreFuncTestSuite);

LITE_TEST_SUIT(utils, kvStore, KvStoreFuncTestSuite);

   int ret = UtilsSetValue(key, value);
   TEST_ASSERT_EQUAL_INT(0, ret);

   ret = UtilsDeleteValue(key);
   TEST_ASSERT_EQUAL_INT(0, ret);
};

RUN_TEST_SUITE(KvStoreFuncTestSuite);

2.3 编译文件

在每个测试套件目录下新建BUILD.gn文件,用于指定构建目标的名称,依赖的头文件,依赖的库文件等。

import("//test/xts/tools/lite/build/suite_lite.gni")

hctest_suite("KvStoreTest") {
  suite_name = "acts"
  sources = [ "src/kvstore_func_test.c" ]

  include_dirs = [
    "src",
    "//utils/native/lite/include",
    "//base/iot_hardware/peripheral/interfaces/kits",
  ]
  cflags = [ "-Wno-error" ]
}

2.4 配置文件

在每个测试套件目录下新建Test.tmpl文件,内容如下:

{
    "description": "Config for $module test cases",
    "environment": [
        {
            "type": "device",
            "label": "wifiiot"
        }
    ],
    "kits": [
        {
            "type": "DeployKit",
            "timeout": "20000",
            "burn_file": "$subsystem/$module.bin"
        }
    ],
    "driver": {
        "type": "CTestLite"
    }
}

2.5 配置编译目标

进入test/developertest/src/core/build目录,在build_lite_testcases.sh文件中按如下格式添加构建目标路径:

BUILD_TARGETS="${BUILD_TARGETS},//utils/native/lite/test/kv_store_hal:KvStoreTest"

备注:必须是完成的构建目标路径

3 用例编译

3.1 编译用例

1、编译所有用例

./test/developertest/src/core/build/build_lite_testcases.sh product=wifiiot_hispark_pegasus kernel=liteos_m

2、编译指定目标的用例

./test/developertest/src/core/build/build_lite_testcases.sh product=wifiiot_hispark_pegasus kernel=liteos_m target=//utils/native/lite/test/kv_store_hal:KvStoreTest

3.2 输出目录

测试用例输出路径为out/hispark_pegasus/wifiiot_hispark_pegasus/test,其目录结构如下:

test
  ├── module_info.json
  ├── test_component.json
  └── unittest
      └── utils
          ├── KvStoreTest.bin
          └── KvStoreTest.json

4 用例执行

参考鸿蒙脱离源码执行测试用例的方法。

备注:L0用例目前只能在Windows下执行。
