2. 测试用例开发

2.1 智能代码生成

// test-generator.ets
@Component
struct TestGenerator {
  @Prop component: Component;
  
  build() {
    Column() {
      Button('生成单元测试')
        .onClick(() => this.generateUnitTest())
      
      Button('生成UI测试')
        .onClick(() => this.generateUITest())
    }
  }

  private generateUnitTest() {
    const code = `
    describe('${this.component.name}', () => {
      it('状态更新测试', () => {
        const comp = renderComponent(${this.component.name});
        comp.setState({ count: 1 });
        expect(comp.find('count').text).toBe('1');
      });
    });`;
    Editor.insert(code);
  }
}

2.2 测试模板库

// template-library.ets
const TEST_TEMPLATES = {
  network: `test('网络请求测试', async () => {
    const res = await fetch('/api');
    expect(res.status).toBe(200);
  });`,
  
  storage: `test('本地存储测试', () => {
    Storage.write('key', 'value');
    expect(Storage.read('key')).toBe('value');
  });`
};

function insertTemplate(templateKey: string) {
  Editor.insert(TEST_TEMPLATES[templateKey]);
}

3. 云测试集成

3.1 设备选择器

// device-picker.ets
@Component
struct DeviceSelector {
  @State devices: CloudDevice[] = [];
  
  onInit() {
    CloudTest.listDevices().then(list => {
      this.devices = list;
    });
  }

  build() {
    List() {
      ForEach(this.devices, device => {
        ListItem() {
          Text(device.name)
          Toggle()
            .onChange(checked => {
              CloudTest.selectDevice(device.id, checked);
            })
        }
      })
    }
  }
}

3.2 测试任务提交

// test-launcher.ets
async function launchCloudTest() {
  const selectedDevices = CloudTest.getSelectedDevices();
  const testFiles = Editor.getOpenTestFiles();
  
  const job = await CloudTest.submitJob({
    devices: selectedDevices,
    testCases: testFiles,
    config: {
      videoRecord: true,
      performanceMetrics: true
    }
  });
  
  return job.id;
}

4. 实时结果反馈

4.1 测试进度监控

// progress-monitor.ets
class TestProgress {
  static showRealTimeProgress(jobId: string) {
    const socket = new WebSocket(`wss://cloud-test/ws/${jobId}`);
    
    socket.onmessage = (event) => {
      const data = JSON.parse(event.data);
      ProgressBar.update(data.progress);
      
      if (data.type === 'log') {
        Console.append(data.message);
      }
      
      if (data.type === 'crash') {
        CrashAnalyzer.show(data.snapshot);
      }
    };
  }
}

4.2 可视化报告

// report-viewer.ets
@Component
struct TestReport {
  @Prop jobId: string;
  @State report: CloudReport;
  
  onInit() {
    CloudTest.getReport(this.jobId).then(report => {
      this.report = report;
    });
  }

  build() {
    Grid() {
      GridItem() {
        PieChart({
          data: this.report.stats,
          title: '通过率'
        })
      }
      
      GridItem() {
        FailureList({
          items: this.report.failures,
          onTap: (item) => showDetails(item)
        })
      }
    }
  }
}

5. 调试工具集成

5.1 设备日志流

// log-stream.ets
class DeviceLogger {
  static stream(deviceId: string) {
    const terminal = new Terminal(`Device_${deviceId}`);
    CloudTest.streamLogs(deviceId, (log) => {
      terminal.write(log);
    });
    return terminal;
  }
}

5.2 远程调试

// remote-debug.ets
function startDebugSession(jobId: string) {
  const debugConfig = {
    type: 'harmony-remote',
    name: 'Cloud Debug',
    request: 'attach',
    jobId: jobId,
    port: 9229
  };
  
  DebugSession.start(debugConfig, {
    onBreakpoint: (frame) => {
      StackTrace.show(frame);
    }
  });
}

6. 性能分析工具

6.1 性能仪表盘

// performance-dashboard.ets
@Component
struct PerfDashboard {
  @Link metrics: PerfMetrics;
  
  build() {
    Column() {
      Gauge({
        value: this.metrics.fps,
        min: 0,
        max: 60,
        title: '帧率'
      })
      
      LineChart({
        data: this.metrics.memoryHistory,
        title: '内存占用'
      })
    }
  }
}

6.2 热点分析

// hotspot.ets
function analyzeHotSpots() {
  const profile = Profiler.capture();
  const hotspots = FlameGraph.analyze(profile);
  
  Editor.highlightLines(
    hotspots.map(h => ({
      file: h.file,
      line: h.line,
      message: `${h.method} (${h.percentage}%)`
    }))
  );
}

7. 代码示例

7.1 完整工作流

// workflow.ets
describe('登录流程', () => {
  it('应成功登录', async () => {
    await LoginPage.enterCredentials('user', 'pass');
    await LoginPage.tapSubmit();
    expect(HomePage.isVisible()).toBeTruthy();
  });
});

// 在IDE中右键选择"Run on Cloud"
function runOnCloud() {
  const devices = ['Mate50', 'P50', 'MatePad'];
  const job = await CloudTest.run({
    tests: 'login.test.ets',
    devices,
    env: { locale: 'zh-CN' }
  });
  
  TestMonitor.show(job.id);
}

7.2 CI/CD集成

# .github/workflows/test.yml
jobs:
  harmony-test:
    runs-on: ubuntu-latest
    steps:
      - uses: harmonyos/cloud-test-action@v1
        with:
          test-files: '**/*.test.ets'
          devices: 'phone,tablet'
          token: ${{ secrets.CLOUD_TOKEN }}

8. 插件配置

8.1 用户设置

// settings.json
{
  "harmony.test.cloudUrl": "https://cloud.harmonyos.com",
  "harmony.test.defaultDevices": ["P50", "MatePad"],
  "harmony.test.autoUpload": true,
  "harmony.test.recordVideo": false
}

8.2 快捷键绑定

// keybindings.json
{
  "command": "harmonyTest.runCurrent",
  "key": "ctrl+alt+t",
  "when": "editorTextFocus"
}

9. 扩展API

9.1 自定义测试框架

// custom-runner.ets
interface TestFramework {
  name: string;
  detect: (file: string) => boolean;
  run: (files: string[]) => Promise<TestResult>;
}

function registerFramework(framework: TestFramework) {
  TestEngine.register(framework);
}

9.2 结果处理器

// result-processor.ets
interface ResultHandler {
  (result: TestResult): void;
}

function addResultHandler(handler: ResultHandler) {
  TestReporter.addHandler(handler);
}

// 示例：测试失败时通知
addResultHandler(result => {
  if (!result.passed) {
    Notification.show({
      title: '测试失败',
      message: `${result.failed}个用例未通过`
    });
  }
});

10. 安全机制

10.1 数据加密

// security.ets
class TestDataEncryptor {
  static encrypt(data: string): string {
    return CryptoKit.AES256GCM.encrypt(
      data, 
      KeyChain.get('test-key')
    );
  }
  
  static decrypt(cipher: string): string {
    return CryptoKit.AES256GCM.decrypt(
      cipher,
      KeyChain.get('test-key')
    );
  }
}

10.2 权限控制

// auth.ets
class CloudAuthenticator {
  static async checkPermission() {
    const scopes = ['test:run', 'device:access'];
    return await Auth.check(scopes);
  }
}

11. 性能优化

11.1 智能测试分片

// test-sharding.ets
function optimizeTestDistribution(tests: TestFile[]) {
  const history = TestHistory.load();
  return tests.map(test => ({
    file: test,
    weight: history.getDuration(test) || 1
  }));
}

11.2 缓存策略

// cache.ets
class TestCache {
  static async get(key: string) {
    if (await Cache.hasValid(key)) {
      return Cache.read(key);
    }
    return null;
  }
  
  static set(key: string, data: any) {
    Cache.write(key, data, { ttl: 3600 });
  }
}
