2. 设备集群管理

2.1 设备注册与心跳

// device-registry.ets
class DeviceManager {
  private static devices: Map<string, Device> = new Map();

  static async registerDevice(device: Device) {
    this.devices.set(device.id, device);
    await DB.insert('active_devices', {
      id: device.id,
      lastHeartbeat: Date.now(),
      capabilities: device.capabilities
    });
  }

  static async checkHeartbeat() {
    const offlineDevices = [];
    for (const [id, device] of this.devices) {
      if (Date.now() - device.lastHeartbeat > 30000) {
        offlineDevices.push(id);
        this.devices.delete(id);
      }
    }
    return offlineDevices;
  }
}

2.2 设备筛选API

// device-selector.ets
function selectDevices(requirements: TestRequirements): Device[] {
  return Array.from(DeviceManager.devices.values())
    .filter(device => 
      device.capabilities.screenSize >= requirements.minScreen &&
      device.osVersion >= requirements.minOS &&
      device.status === 'idle'
    )
    .slice(0, requirements.maxDevices);
}

3. 分布式任务调度

3.1 任务分片算法

// task-slicer.ets
function sliceTestSuite(tests: TestCase[], deviceCount: number): TestSlice[] {
  const slices: TestSlice[] = [];
  const testsPerDevice = Math.ceil(tests.length / deviceCount);
  
  for (let i = 0; i < deviceCount; i++) {
    slices.push({
      deviceId: `device_${i}`,
      tests: tests.slice(i * testsPerDevice, (i + 1) * testsPerDevice)
    });
  }
  
  return slices;
}

3.2 任务队列管理

// task-queue.ets
class DistributedQueue {
  private static queue: Task[] = [];
  private static inProgress: Map<string, Task> = new Map();

  static async enqueue(task: Task) {
    this.queue.push(task);
    await this.dispatch();
  }

  private static async dispatch() {
    while (this.queue.length > 0) {
      const idleDevices = DeviceManager.getIdleDevices();
      if (idleDevices.length === 0) break;
      
      const task = this.queue.shift()!;
      const device = idleDevices[0];
      
      this.inProgress.set(device.id, task);
      await DeviceExecutor.run(device.id, task);
    }
  }
}

4. 大规模设备控制

4.1 批量操作协议

// batch-control.ets
class DeviceController {
  static async parallelExecute(devices: string[], command: DeviceCommand) {
    const results = await Promise.allSettled(
      devices.map(id => this.sendCommand(id, command))
    );
    
    return results.map((result, i) => ({
      device: devices[i],
      status: result.status,
      output: result.status === 'fulfilled' ? result.value : result.reason
    }));
  }

  private static async sendCommand(id: string, cmd: DeviceCommand) {
    const device = DeviceManager.getDevice(id);
    return device.channel.execute(cmd);
  }
}

4.2 设备状态同步

// state-sync.ets
function syncDeviceStates() {
  const states = new Map<string, DeviceState>();
  
  DeviceManager.devices.forEach((device, id) => {
    states.set(id, {
      battery: device.batteryLevel,
      memory: device.usedMemory,
      temperature: device.cpuTemp
    });
  });
  
  return CloudAPI.reportStates(Array.from(states.entries()));
}

5. 测试执行引擎

5.1 设备端测试运行器

// device-runner.ets
class DeviceTestRunner {
  static async run(testSlice: TestSlice): Promise<TestResult> {
    const results: TestResult[] = [];
    
    for (const test of testSlice.tests) {
      const result = await this.executeSingleTest(test);
      results.push(result);
      
      if (result.status === 'failed' && testSlice.stopOnFailure) {
        break;
      }
    }
    
    return this.aggregateResults(results);
  }

  private static async executeSingleTest(test: TestCase) {
    try {
      await DeviceScreen.capture('before');
      const output = await TestEngine.run(test);
      await DeviceScreen.capture('after');
      
      return {
        testId: test.id,
        status: 'passed',
        output
      };
    } catch (error) {
      return {
        testId: test.id,
        status: 'failed',
        error: error.message
      };
    }
  }
}

5.2 异常恢复机制

// failure-handler.ets
class RecoveryManager {
  static async handleFailure(deviceId: string, error: Error) {
    // 1. 尝试软重启
    await DeviceController.softReset(deviceId);
    
    // 2. 检查设备状态
    const state = await DeviceDiagnostics.check(deviceId);
    
    // 3. 必要时重新刷机
    if (state.requiresFlash) {
      await FlashTool.reflash(deviceId);
    }
    
    // 4. 重新加入集群
    await DeviceManager.reregister(deviceId);
  }
}

6. 结果聚合分析

6.1 分布式结果收集

// result-aggregator.ets
class ResultCollector {
  private static results: Map<string, TestResult> = new Map();

  static async collect(deviceId: string, result: TestResult) {
    this.results.set(`${deviceId}-${result.testId}`, result);
    
    if (this.isBatchComplete()) {
      await this.generateReport();
    }
  }

  private static isBatchComplete(): boolean {
    const expected = DistributedQueue.totalTasks;
    return this.results.size >= expected;
  }
}

6.2 智能差异分析

// diff-analyzer.ets
function analyzeVisualDiffs(results: TestResult[]) {
  const diffs: DiffResult[] = [];
  
  for (const result of results) {
    if (result.screenshots) {
      const diff = ImageDiff.compare(
        result.screenshots.before,
        result.screenshots.after
      );
      
      if (diff.score > 0.1) {
        diffs.push({
          testId: result.testId,
          device: result.deviceId,
          diffScore: diff.score,
          highlight: diff.highlightAreas
        });
      }
    }
  }
  
  return diffs;
}

7. 性能优化策略

7.1 设备分组策略

// device-grouping.ets
function optimizeGrouping(devices: Device[]): DeviceGroup[] {
  return [
    ...groupBy(devices, 'model'),
    ...groupBy(devices, 'osVersion'),
    ...groupBy(devices, 'screenSize')
  ].filter(g => g.devices.length > 5);
}

function groupBy(devices: Device[], key: keyof Device) {
  const groups = new Map<string, Device[]>();
  
  devices.forEach(device => {
    const groupKey = String(device[key]);
    if (!groups.has(groupKey)) {
      groups.set(groupKey, []);
    }
    groups.get(groupKey)!.push(device);
  });
  
  return Array.from(groups.entries()).map(([key, devices]) => ({
    key,
    devices
  }));
}

7.2 测试缓存机制

// test-cache.ets
class TestCache {
  private static cache = new LRU<string, TestOutput>(1000);
  
  static async get(test: TestCase): Promise<TestOutput | null> {
    const key = this.getCacheKey(test);
    if (this.cache.has(key)) {
      return this.cache.get(key)!;
    }
    return null;
  }
  
  static async set(test: TestCase, output: TestOutput) {
    const key = this.getCacheKey(test);
    this.cache.set(key, output);
  }
  
  private static getCacheKey(test: TestCase): string {
    return `${test.id}-${test.hash}`;
  }
}

8. 安全控制机制

8.1 设备访问鉴权

// device-auth.ets
class DeviceAuthenticator {
  static async verifyToken(deviceId: string, token: string) {
    const validToken = await KeyVault.get(`device-${deviceId}-token`);
    return crypto.timingSafeEqual(
      Buffer.from(token),
      Buffer.from(validToken)
    );
  }
}

8.2 数据加密传输

// secure-channel.ets
class SecureChannel {
  static async encryptForDevice(deviceId: string, data: any) {
    const pubKey = await DeviceKeyStore.getPublicKey(deviceId);
    return crypto.publicEncrypt(
      pubKey,
      Buffer.from(JSON.stringify(data))
    );
  }
  
  static async decryptFromDevice(deviceId: string, cipher: Buffer) {
    const privKey = await KeyVault.get(`device-${deviceId}-priv`);
    return JSON.parse(
      crypto.privateDecrypt(privKey, cipher).toString()
    );
  }
}

9. 完整调度示例

// create-job.ets
async function createMassiveTestJob() {
  const tests = await TestLoader.loadAll();
  const devices = selectDevices({
    minScreen: 5,
    minOS: '3.0',
    maxDevices: 100
  });
  
  const job = await CloudTest.createJob({
    name: 'Full Regression',
    tests,
    devices,
    priority: 'high'
  });
  
  return job.id;
}

9.2 监控任务状态

// job-monitor.ets
class JobMonitor {
  static async watch(jobId: string) {
    const socket = new WebSocket(`wss://cloud-test/jobs/${jobId}/ws`);
    
    socket.onmessage = (event) => {
      const data = JSON.parse(event.data);
      switch (data.type) {
        case 'progress':
          ProgressBar.update(data.completed, data.total);
          break;
        case 'deviceUpdate':
          DevicePanel.refresh(data.device);
          break;
        case 'completed':
          this.showFinalReport(data.results);
