以下为 ​​将HarmonyOS 5测试结果转化为交互式HTML报表的完整ArkTS实现方案​​，包含数据解析、可视化渲染和交互功能代码：

1. 报表架构设计

2. 核心数据转换

2.1 JUnit XML解析

// junit-parser.ets
import { parseString } from '@ohos/xml2js';

export async function parseJUnit(xml: string): Promise<TestReport> {
  return new Promise((resolve, reject) => {
    parseString(xml, (err, result) => {
      if (err) return reject(err);
      
      const suites = result.testsuites.testsuite.map(suite => ({
        name: suite.$.name,
        tests: parseInt(suite.$.tests),
        failures: parseInt(suite.$.failures),
        time: parseFloat(suite.$.time),
        cases: suite.testcase.map(testcase => ({
          name: testcase.$.name,
          class: testcase.$.classname,
          time: parseFloat(testcase.$.time),
          status: testcase.failure ? 'failed' : 'passed',
          failure: testcase.failure?.[0]?._
        }))
      }));
      
      resolve({
        meta: {
          timestamp: new Date().toISOString(),
          environment: Device.getEnvInfo()
        },
        suites
      });
    });
  });
}

2.2 数据模型转换

// report-model.ets
interface TestSuite {
  name: string;
  passRate: number;
  duration: number;
  cases: TestCase[];
}

export function transformToView(report: TestReport): TestSuite[] {
  return report.suites.map(suite => ({
    name: suite.name,
    passRate: (suite.tests - suite.failures) / suite.tests * 100,
    duration: suite.time,
    cases: suite.cases.map(testcase => ({
      ...testcase,
      isFlaky: checkFlakiness(testcase.name)
    }))
  }));
}

3. 可视化组件实现

3.1 主仪表盘

// dashboard.ets
import { Chart, Gauge } from '@ohos/viz';

export function renderDashboard(suites: TestSuite[]) {
  const totalPassRate = suites.reduce((sum, s) => sum + s.passRate, 0) / suites.length;
  
  return `
    <div class="dashboard">
      ${new Gauge({
        value: totalPassRate,
        label: '总通过率',
        thresholds: [90, 95]
      }).render()}
      
      ${new Chart({
        type: 'bar',
        data: suites.map(s => ({
          x: s.name,
          y: s.passRate,
          color: s.passRate < 90 ? '#FF5252' : '#4CAF50'
        })),
        title: '各模块通过率'
      }).render()}
    </div>
  `;
}

3.2 用例详情表格

// case-table.ets
export function renderCaseTable(cases: TestCase[]) {
  return `
    <table class="case-table">
      <thead>
        <tr>
          <th>用例名</th>
          <th>状态</th>
          <th>耗时(s)</th>
          <th>操作</th>
        </tr>
      </thead>
      <tbody>
        ${cases.map(case => `
          <tr data-case="${case.name}" class="${case.status}">
            <td>${case.class}.${case.name}</td>
            <td>${renderStatusBadge(case.status)}</td>
            <td>${case.time.toFixed(2)}</td>
            <td>
              <button onclick="showError('${case.name}')">
                ${case.status === 'failed' ? '查看错误' : ''}
              </button>
            </td>
          </tr>
        `).join('')}
      </tbody>
    </table>
  `;
}

4. 交互功能实现

4.1 错误详情弹窗

// error-modal.ets
export function renderErrorModal() {
  return `
    <div id="error-modal" class="modal">
      <div class="modal-content">
        <span class="close" onclick="closeModal()">&times;</span>
        <pre id="error-detail"></pre>
      </div>
    </div>
    
    <script>
      function showError(caseName) {
        const error = cases.find(c => c.name === caseName)?.failure;
        document.getElementById('error-detail').textContent = error || '无错误信息';
        document.getElementById('error-modal').style.display = 'block';
      }
      
      function closeModal() {
        document.getElementById('error-modal').style.display = 'none';
      }
    </script>
  `;
}

4.2 趋势对比

// trend-comparison.ets
import { fetchHistory } from './report-history';

export async function renderTrend(suiteName: string) {
  const history = await fetchHistory(suiteName, 7);
  
  return new Chart({
    type: 'line',
    data: history.map((day, i) => ({
      x: `Day ${i + 1}`,
      y: day.passRate,
      group: suiteName
    })),
    options: {
      yAxis: { min: 0, max: 100 },
      annotations: [
        { value: 90, label: '最低标准' }
      ]
    }
  }).render();
}

5. 完整报表生成

5.1 组装完整HTML

// report-generator.ets
export function generateHTML(report: TestReport) {
  const suites = transformToView(report);
  
  return `
    <!DOCTYPE html>
    <html>
    <head>
      <title>测试报告 - ${new Date().toLocaleString()}</title>
      <style>
        ${require('!raw-loader!./styles/report.css')}
      </style>
    </head>
    <body>
      <header>
        <h1>HarmonyOS测试报告</h1>
        <p>环境: ${report.meta.environment}</p>
      </header>
      
      ${renderDashboard(suites)}
      
      <section class="suites">
        ${suites.map(suite => `
          <div class="suite">
            <h2>${suite.name}</h2>
            <div class="trend">${renderTrend(suite.name)}</div>
            ${renderCaseTable(suite.cases)}
          </div>
        `).join('')}
      </section>
      
      ${renderErrorModal()}
      
      <script>
        const cases = ${JSON.stringify(suites.flatMap(s => s.cases))};
        ${require('!raw-loader!./scripts/interaction.js')}
      </script>
    </body>
    </html>
  `;
}

5.2 样式文件示例

/* styles/report.css */
.dashboard {
  display: grid;
  grid-template-columns: 1fr 2fr;
  gap: 20px;
}

.suite {
  margin-bottom: 30px;
  border: 1px solid #eee;
  padding: 15px;
}

.case-table tr.failed {
  background-color: #FFEBEE;
}

.modal {
  display: none;
  position: fixed;
  z-index: 1;
  left: 0;
  top: 0;
  width: 100%;
  height: 100%;
  background-color: rgba(0,0,0,0.4);
}

6. 使用示例

6.1 命令行工具

// cli.ets
import { parseJUnit, generateHTML } from './report';

async function main() {
  const xml = await readFile('results/junit.xml');
  const report = await parseJUnit(xml);
  const html = generateHTML(report);
  
  await writeFile('report.html', html);
  console.log('报表已生成: report.html');
}

main().catch(console.error);

6.2 集成到测试流程

// test-runner.ets
import { runTests } from '@ohos/test';
import { generateHTML } from './report';

export async function runAndReport() {
  const results = await runTests();
  const html = generateHTML(results);
  
  if (process.env.CI) {
    await uploadReport(html);
  } else {
    await writeFile('report.html', html);
    open('report.html');
  }
}

7. 高级功能扩展

7.1 历史趋势存储

// report-history.ets
import { Database } from '@ohos.sqlite';

export async function saveDailyReport(report: TestReport) {
  const db = new Database('test-history.db');
  
  await db.run(`
    INSERT INTO reports (date, pass_rate, total_tests)
    VALUES (?, ?, ?)
  `, [
    new Date().toISOString(),
    report.summary.passRate,
    report.summary.totalTests
  ]);
  
  report.suites.forEach(async suite => {
    await db.run(`
      INSERT INTO suite_stats 
      (report_date, suite_name, pass_rate, duration)
      VALUES (?, ?, ?, ?)
    `, [
      new Date().toISOString(),
      suite.name,
      suite.passRate,
      suite.duration
    ]);
  });
}

7.2 多维度筛选

// report-filter.ets
export function createFilter(report: TestReport) {
  return {
    byStatus(status: string) {
      return transformToView({
        ...report,
        suites: report.suites.map(suite => ({
          ...suite,
          cases: suite.cases.filter(c => c.status === status)
        }))
      });
    },
    byDuration(min: number, max: number) {
      return transformToView({
        ...report,
        suites: report.suites.map(suite => ({
          ...suite,
          cases: suite.cases.filter(c => 
            c.time >= min && c.time <= max
          )
        }))
      });
    }
  };
}

8. 报表效果指标
