HarmonyOS5 全设备覆盖：在DevEco Cloud上自动测试Phone+TV+Watch三端兼容性

以下为 ​​基于DevEco Cloud实现HarmonyOS 5全设备自动化兼容性测试的完整方案​​，包含多设备测试编排、兼容性适配和自动化报告的ArkTS/ArkUI代码实现：

---

1. 测试架构设计

---

2. 多设备测试基础配置

2.1 设备矩阵定义

// device-matrix.ets
export const DeviceMatrix = [
  {
    type: 'phone',
    models: ['Mate60', 'P70'],
    osVersion: ['5.0', '5.1']
  },
  {
    type: 'tv',
    models: ['Vision75', 'Vision85'],
    resolution: ['4K', '8K']
  },
  {
    type: 'watch',
    models: ['Watch4', 'Watch5'],
    shape: ['round', 'square']
  }
] as const;

2.2 测试任务描述文件

// test-config.json
{
  "testSuites": ["layout", "interaction", "performance"],
  "deviceFilters": {
    "phone": { "minRam": 4, "minApi": 5 },
    "tv": { "minWidth": 1920 },
    "watch": { "hasRoundScreen": true }
  }
}

---

3. 核心测试逻辑

3.1 跨设备布局测试

// layout-test.ets
import { Device } from '@ohos.cloud';

export function testResponsiveLayout() {
  describe('布局兼容性', () => {
    DeviceMatrix.forEach(device => {
      it(`应在${device.type}上正确渲染`, async () => {
        await Device.connect(device);
        const screenshot = await takeScreenshot();
        
        expect(screenshot)
          .toMatchBaseline(`layout-${device.type}.png`);
      });
    });
  });
}

3.2 交互一致性测试

// interaction-test.ets
export function testCrossDeviceInteraction() {
  const gestures = [
    { name: 'swipe', phone: 'left', tv: 'right', watch: 'up' },
    { name: 'tap', phone: 'single', tv: 'long', watch: 'double' }
  ];

  gestures.forEach(gesture => {
    it(`${gesture.name}手势应统一响应`, async () => {
      const results = await Promise.all(
        DeviceMatrix.map(device => 
          testGestureOnDevice(device, gesture[device.type])
        )
      );
      
      expect(results).toHaveSameBehavior();
    });
  });
}

---

4. 设备特性适配层

4.1 屏幕适配策略

// screen-adapter.ets
export function getDeviceSpecificStyle(deviceType: string) {
  const styles = {
    phone: { fontSize: 16, padding: 12 },
    tv: { fontSize: 28, padding: 24 },
    watch: { fontSize: 12, padding: 8 }
  };
  
  return styles[deviceType] || styles.phone;
}

@Component
struct ResponsiveComponent {
  @Prop deviceType: string;

  build() {
    const style = getDeviceSpecificStyle(this.deviceType);
    
    Column() {
      Text('自适应文本')
        .fontSize(style.fontSize)
        .padding(style.padding)
    }
  }
}

4.2 输入设备抽象

// input-adapter.ets
export function simulateInput(deviceType: string, action: string) {
  const handlers = {
    phone: {
      tap: () => TouchScreen.tap(),
      swipe: () => TouchScreen.swipe()
    },
    tv: {
      tap: () => RemoteControl.press('OK'),
      swipe: () => RemoteControl.hold('RIGHT')
    },
    watch: {
      tap: () => RotateBezel.click(),
      swipe: () => RotateBezel.rotate()
    }
  };
  
  return handlers[deviceType][action]();
}

---

5. 云端测试编排

5.1 并行测试任务

// cloud-test.ets
import { TestOrchestrator } from '@ohos.cloud';

export async function runFullTest() {
  const orchestrator = new TestOrchestrator({
    maxParallel: 5, // 最大并行设备数
    timeout: 300000  // 5分钟超时
  });

  await orchestrator.schedule(
    DeviceMatrix,
    [testResponsiveLayout, testCrossDeviceInteraction]
  );
}

5.2 设备分配策略

// device-scheduler.ets
export class DeviceScheduler {
  static getOptimalDevice(testType: string) {
    const strategy = {
      layout: { priority: ['tv', 'phone', 'watch'] },
      interaction: { priority: ['phone', 'watch', 'tv'] }
    };
    
    return DeviceMatrix.sort((a, b) => 
      strategy[testType].priority.indexOf(a.type) -
      strategy[testType].priority.indexOf(b.type)
    );
  }
}

---

6. 测试报告生成

6.1 兼容性评分

// report-generator.ets
export function generateCompatibilityReport(results) {
  const score = calculateScore(results);
  
  return {
    devices: DeviceMatrix.map(d => ({
      type: d.type,
      models: d.models,
      passRate: `${score[d.type]}%`
    })),
    issues: groupByProblemType(results.failures)
  };
}

function calculateScore(results) {
  return DeviceMatrix.reduce((acc, device) => {
    const passed = results.filter(r => 
      r.device === device.type && r.passed
    ).length;
    acc[device.type] = Math.round((passed / results.length) * 100);
    return acc;
  }, {});
}

6.2 可视化报告

// visual-report.ets
import { Chart, Table } from '@ohos.report';

export function renderReport(data) {
  new Chart({
    type: 'bar',
    data: Object.entries(data.devices).map(([type, info]) => ({
      x: type,
      y: info.passRate
    }))
  }).render('compatibility-chart.html');

  new Table({
    headers: ['设备类型', '通过率', '主要问题'],
    rows: data.devices.map(d => [
      d.type, 
      d.passRate,
      data.issues[d.type]?.join(', ') || '无'
    ])
  }).render('issue-table.html');
}

7. 完整工作流示例

7.1 测试入口文件

// main-test.ets
import { runFullTest } from './cloud-test';
import { generateCompatibilityReport } from './report';

async function main() {
  const results = await runFullTest();
  const report = generateCompatibilityReport(results);
  
  console.log(JSON.stringify(report, null, 2));
  if (report.score < 95) {
    process.exit(1); // 低于95分视为失败
  }
}

main();

7.2 CI/CD集成

# .github/workflows/test.yml
name: Multi-Device Test
on: [push]

jobs:
  test:
    runs-on: ubuntu-latest
    steps:
      - uses: huawei/deveco-cloud-action@v2
        with:
          test-command: 'ark test main-test.ets'
          device-pool: 'phone,tv,watch'
