OH4.0的应用UT开发原理

显示全部楼层

背景

新建工程

新建工程自带的UT：使用步骤就是点开Ability.test.ets然后点击abilityTest下的那个绿色箭头就可以看到下面的输出，默认工程会建立一个用例，所以执行结果就是Tests passed： 1

运行日志可通过hilog查看

命令行执行

aa test -b com.example.myapplication -m entry_test -s unittest /ets/testrunner/OpenHarmonyTestRunner -s class ActsAbilityTest -s timeout 15000

以上内容就是入门级使用说明，后面讲点理论

ArtTS单元测试框架

OpenHarmony自动化测试框架代码部件仓arkXtest，包含单元测试框架(JsUnit)和Ui测试框架(UiTest)。单元测试框架(JsUnit)提供单元测试用例执行能力，提供用例编写基础接口，生成对应报告，用于测试系统或应用接口。Ui测试框架(UiTest)通过简洁易用的API提供查找和操作界面控件能力，支持用户开发基于界面操作的自动化测试脚本。

单元测试框架功能特性（jsunit）

No.	特性	功能说明
1	基础流程	支持编写及异步执行基础用例。
2	断言库	判断用例实际期望值与预期值是否相符。
3	Mock能力	支持函数级mock能力，对定义的函数进行mock后修改函数的行为，使其返回指定的值或者执行某种动作。
4	数据驱动	提供数据驱动能力，支持复用同一个测试脚本，使用不同输入数据驱动执行。
5	专项能力	支持测试套与用例筛选、随机执行、压力测试、超时设置、遇错即停模式等。

使用说明

基础流程（jsunit） 测试用例采用业内通用语法，**describe代表一个测试套， it代表一条用例。| No. | API | 功能说明 | | ------------- | --------------------------- | ---------------------------------------------------------------------------------------------------------------------------------- | | 1 | describe | 定义一个测试套，支持两个参数：测试套名称和测试套函数。 | | 2 | beforeAll | 在测试套内定义一个预置条件，在所有测试用例开始前执行且仅执行一次，支持一个参数：预置动作函数。 | | 3 | beforeEach | 在测试套内定义一个单元预置条件，在每条测试用例开始前执行，执行次数与it定义的测试用例数一致，支持一个参数：预置动作函数。 | | 4 | afterEach | 在测试套内定义一个单元清理条件，在每条测试用例结束后执行，执行次数与it定义的测试用例数一致，支持一个参数：清理动作函数。 | | 5 | afterAll | 在测试套内定义一个清理条件，在所有测试用例结束后执行且仅执行一次，支持一个参数：清理动作函数。 | | 6 | beforeItSpecified | 在测试套内定义一个单元预置条件，仅在指定测试用例开始前执行，支持两个参数：单个用例名称或用例名称数组、预置动作函数。 | | 7 | afterItSpecified | 在测试套内定义一个单元清理条件，仅在指定测试用例结束后执行，支持两个参数：单个用例名称或用例名称数组、清理动作函数 | | 8 | it | 定义一条测试用例，支持三个参数：用例名称，过滤参数和用例函数。 | | 9 | expect | 支持bool类型判断等多种断言方法。 | | 10 | getDescribeName | 获取当前正在执行测试套的名称 | | 11 | getItName | 获取当前正在执行测试用例的名称 | | 12 | getItAttribute | 获取当前正在执行测试用例的级别、粒度、测试类型** |

示例代码（jsunit） 以下就是默认工程里的测试用例：**describe就是定义一个测试套；it就是一个测试用例；什么是测试套？：简单理解就是一组测试用例我们可以定为测试套，比如我要测一个页面的功能，播放，暂停，等等，就可以定义为一个测试套。当然测试套可以可以理解是个大范围，比如完整的一系列功能，比如，所有的arkui的控件测试套这种；什么是测试用例？**：可以理解为一个测试项目，比如说我点了“保存”按钮，会存手机名称这样；再简单点就是点了spinbutton，就会选中；很多测试用例组成一个测试套；

import hilog from '@ohos.hilog';
import { describe, beforeAll, beforeEach, afterEach, afterAll, it, expect } from '@ohos/hypium';

export default function abilityTest() {
  describe('ActsAbilityTest', () => {
    // Defines a test suite. Two parameters are supported: test suite name and test suite function.
    beforeAll(() => {
      // Presets an action, which is performed only once before all test cases of the test suite start.
      // This API supports only one parameter: preset action function.
    })
    beforeEach(() => {
      // Presets an action, which is performed before each unit test case starts.
      // The number of execution times is the same as the number of test cases defined by **it**.
      // This API supports only one parameter: preset action function.
    })
    afterEach(() => {
      // Presets a clear action, which is performed after each unit test case ends.
      // The number of execution times is the same as the number of test cases defined by **it**.
      // This API supports only one parameter: clear action function.
    })
    afterAll(() => {
      // Presets a clear action, which is performed after all test cases of the test suite end.
      // This API supports only one parameter: clear action function.
    })
    it('assertContain', 0, () => {
      // Defines a test case. This API supports three parameters: test case name, filter parameter, and test case function.
      hilog.info(0x0000, 'testTag', '%{public}s', 'it begin');
      let a = 'abc';
      let b = 'b';
      // Defines a variety of assertion methods, which are used to declare expected boolean conditions.
      expect(a).assertContain(b);
      expect(a).assertEqual(a);
    })
  })
}

断言 断言功能列表：

2	assertContain	检验actualvalue中是否包含expectvalue。
3	assertEqual	检验actualvalue是否等于expectvalue[0]。
4	assertFail	抛出一个错误。
5	assertFalse	检验actualvalue是否是false。
6	assertTrue	检验actualvalue是否是true。
7	assertInstanceOf	检验actualvalue是否是expectvalue类型，支持基础类型。
8	assertLarger	检验actualvalue是否大于expectvalue。
9	assertLess	检验actualvalue是否小于expectvalue。
10	assertNull	检验actualvalue是否是null。
11	assertThrowError	检验actualvalue抛出Error内容是否是expectValue。
12	assertUndefined	检验actualvalue是否是undefined。
13	assertNaN	@since1.0.4 检验actualvalue是否是一个NAN
14	assertNegUnlimited	@since1.0.4 检验actualvalue是否等于Number.NEGATIVE_INFINITY
15	assertPosUnlimited	@since1.0.4 检验actualvalue是否等于Number.POSITIVE_INFINITY
16	assertDeepEquals	@since1.0.4 检验actualvalue和expectvalue是否完全相等
17	assertPromiseIsPending	@since1.0.4 判断promise是否处于Pending状态。
18	assertPromiseIsRejected	@since1.0.4 判断promise是否处于Rejected状态。
19	assertPromiseIsRejectedWith	@since1.0.4 判断promise是否处于Rejected状态，并且比较执行的结果值。

以上都是jsunit的断言

单元测试框架功能特性（uitest）

No.	特性	功能说明
1	Driver	Ui测试的入口，提供查找控件，检查控件存在性以及注入按键能力。
2	On	用于描述目标控件特征(文本、id、类型等)，`Driver`根据 `On`描述的控件特征信息来查找控件。
3	Component	Driver查找返回的控件对象，提供查询控件属性，滑动查找等触控和检视能力。
4	UiWindow	Driver查找返回的窗口对象，提供获取窗口属性、操作窗口的能力。

使用说明

引入uitest框架

import {Driver,ON,Component,Uiwindow,MatchPattern} from '@ohos.UiTest'

引入ability

import AbilityDelegatorRegistry from '@ohos.app.ability.abilityDelegatorRegistry';

添加启动应用准备

beforeAll(async (done: Function) => {
  // Presets an action, which is performed only once before all test cases of the test suite start.
  // This API supports only one parameter: preset action function.
  let abilityDelegator = AbilityDelegatorRegistry.getAbilityDelegator();
  try {
    await abilityDelegator.startAbility({
      bundleName: 'com.example.myapplication',
      abilityName: 'EntryAbility'
    });
  } catch (exception) {
    console.info(TAG, `StartAbility_001 exception = ${JSON.stringify(exception)}`);
    expect().assertFail();
  }
  done();
})

添加测试用例

it('StartAbility_001', 0, async (done: Function) => {
  console.info(TAG, 'StartAbility_001 begin');
  let driver = Driver.create();

  await driver.delayMs(100);
  await driver.assertComponentExist(ON.text('Hello World'));
  // find component by text
  let button: Component = await driver.findComponent(ON.text('Hello World').enabled(true))
  // click component
  await button.click()
  // get and assert component text
  let content: string = await button.getText()
  expect(content).assertEqual('Hello World')
  done();
})

须知

On类提供的接口全部是同步接口，使用者可以使用 builder模式链式调用其接口构造控件筛选条件。

Driver和 Component类提供的接口全部是异步接口(Promise形式)，需使用 await语法。

Ui测试用例均需使用**异步**语法编写用例，需遵循单元测试框架异步用例编写规范。

覆盖率结果
为啥没覆盖到，可以点击具体部分查看 红色部分就是没覆盖部分，其实就是生命周期没覆盖，只测试了启动（也就是前台Foreground，没有后台Background，也没有load失败）所以生命周期的测试不完整。

专项能力

- **筛选能力**

按测试用例属性筛选

可以利用hypium提供的Level、Size、TestType 对象，对测试用例进行标记，以区分测试用例的级别、粒度、测试类型，各字段含义及代码如下：

Key	含义说明	Value取值说明
level	用例级别	"0","1","2","3","4", 例如：-s level 1
size	用例粒度	"small","medium","large", 例如：-s size small "small","medium","large", 例如：-s size small
testType	用例测试类型	"function","performance","power","reliability","security","global","compatibility","user","standard","safety","resilience", 例如：-s testType function

示例代码：

import { describe, it, expect, TestType, Size, Level } from '@ohos/hypium';
 export default function attributeTest() {
 describe('attributeTest', () => {
  it("testAttributeIt", TestType.FUNCTION | Size.SMALLTEST | Level.LEVEL0, () => {
   console.info('Hello Test');
  })
 })
}

示例命令:

hdc shell aa test -b xxx -m xxx -s unittest OpenHarmonyTestRunner -s testType function -s size small -s level 0

按测试套/测试用例名称筛选 hypium可以通过指定测试套与测试用例名称，来指定特定用例的执行，测试套与用例名称用“#”号连接，多个用“,”英文逗号分隔

Key	含义说明	Value取值范围
class	指定要执行的测试套&用例	\${describeName}#\${itName}，\${describeName} , 例如：-s class attributeTest#testAttributeIt
notClass	指定不执行的测试套&用例	\${describeName}#\${itName}，\${describeName} , 例如：-s notClass attributeTest#testAttribu

示例代码：

  import { describe, it, expect, TestType, Size, Level } from '@ohos/hypium';

  export default function attributeTest() {
  describe('describeTest_000',  () => {
    it("testIt_00", TestType.FUNCTION | Size.SMALLTEST | Level.LEVEL0,  () => {
      console.info('Hello Test');
    })

    it("testIt_01", TestType.FUNCTION | Size.SMALLTEST | Level.LEVEL0, () => {
      console.info('Hello Test');
    })
  })

  describe('describeTest_001',  () => {
    it("testIt_02", TestType.FUNCTION | Size.SMALLTEST | Level.LEVEL0, () => {
      console.info('Hello Test');
    })
  })
}

示例命令1:

hdc shell aa test -b xxx -m xxx -s unittest OpenHarmonyTestRunner -s class describeTest_000#testIt_00,describeTest_001

该命令作用是执行“describeTest_001”测试套中所用用例，以及“describeTest_000”测试套中的“testIt_00”用例。

示例命令2：

hdc shell aa test -b xxx -m xxx -s unittest OpenHarmonyTestRunner -s notClass describeTest_000#testIt_01

该命令作用是不执行“describeTest_000”测试套中的“testIt_01”用例。

随机执行 使测试套与测试用例随机执行，用于稳定性测试。

Key 含义说明 Value取值范围

random @since1.0.3 测试套、测试用例随机执行 true, 不传参默认为false，例如：-s random true

示例命令：
```
 hdc shell aa test -b xxx -m xxx -s unittest OpenHarmonyTestRunner -s stress 1000
```

UT有用的命令

用例超时时间设置 指定测试用例执行的超时时间，用例实际耗时如果大于超时时间，用例会抛出"timeout"异常，用例结果会显示“excute timeout XXX”

Key 含义说明 Value取值范围

timeout 指定测试用例执行的超时时间 正整数(单位ms)，默认为 5000，例如： -s timeout 15000

示例命令：
```
hdc shell aa test -b xxx -m xxx -s unittest OpenHarmonyTestRunner -s timeout 15000
```

遇错即停模式

Key	含义说明	Value取值范围
breakOnError	@since1.0.6 遇错即停模式，当执行用例断言失败或者发生错误时，退出测试执行流程	true, 不传参默认为false，例如：-s breakOnError true

示例命令：

hdc shell aa test -b xxx -m xxx -s unittest OpenHarmonyTestRunner -s breakOnError true

测试套中用例信息输出 输出测试应用中待执行的测试用例信息

Key 含义说明 Value取值范围

dryRun 显示待执行的测试用例信息全集 true, 不传参默认为false，例如：-s dryRun true

示例命令：
```
hdc shell aa test -b xxx -m xxx -s unittest OpenHarmonyTestRunner -s dryRun true
```
