const commonPorts [3000, 3001, 3002, 5173, 8080, 8000, 4200, 5000, 9000, 1234]; const allPorts [...new Set([...commonPorts, ...customPorts])]; const detectedServers []; for (const port of allPorts) { try { await new Promise((resolve, reject) { const req http.request({ hostname: localhost, port: port, path: /, method: HEAD, timeout: 500 }, (res) { if (res.statusCode 500) { detectedServers.push(http://localhost:${port}); } resolve(); }); req.on(error, () resolve()); req.on(timeout, () { req.destroy(); resolve(); }); req.end(); }); } catch (e) { // Port not available, continue } } return detectedServers; }脚本生成与执行隔离机制为确保测试脚本的安全性和可维护性Playwright-Skill采用临时文件系统隔离策略。所有生成的测试脚本都保存在/tmp/playwright-test-*.js目录中通过操作系统自动清理机制避免文件残留。执行引擎通过run.js包装器提供统一的模块解析和依赖管理// run.js执行器核心逻辑 const path require(path); const { spawn } require(child_process); async function executeScript(scriptPath) { const env { ...process.env, NODE_PATH: path.join(__dirname, node_modules), PW_HEADER_NAME: process.env.PW_HEADER_NAME, PW_HEADER_VALUE: process.env.PW_HEADER_VALUE, PW_EXTRA_HEADERS: process.env.PW_EXTRA_HEADERS }; const child spawn(node, [scriptPath], { env, stdio: inherit, cwd: __dirname }); return new Promise((resolve, reject) { child.on(close, (code) { resolve({ exitCode: code }); }); child.on(error, reject); }); }自定义HTTP头注入机制架构为支持复杂的测试场景Playwright-Skill实现了灵活的自定义HTTP头注入机制。通过环境变量配置可以在所有请求中自动添加标识头便于后端服务识别自动化流量并返回优化响应。HTTP头配置参数对比表环境变量格式用途典型应用场景PW_HEADER_NAME字符串单头名称自动化流量标识PW_HEADER_VALUE字符串单头值测试环境识别PW_EXTRA_HEADERSJSON对象多头配置复杂测试场景// 头注入实现逻辑 function getExtraHeadersFromEnv() { const headerName process.env.PW_HEADER_NAME; const headerValue process.env.PW_HEADER_VALUE; if (headerName headerValue) { return { [headerName]: headerValue }; } const headersJson process.env.PW_EXTRA_HEADERS; if (headersJson) { try { const parsed JSON.parse(headersJson); if (typeof parsed object parsed ! null !Array.isArray(parsed)) { return parsed; } } catch (e) { console.warn(Failed to parse PW_EXTRA_HEADERS as JSON:, e.message); } } return null; }实施路径从基础到高级的自动化测试实践指南基础测试场景实现策略响应式设计验证是现代Web开发的关键需求。Playwright-Skill通过多视口自动测试确保应用在不同设备上的表现一致性。// 多设备视口测试实现 async function testResponsiveDesign(url) { const browser await chromium.launch({ headless: false }); const page await browser.newPage(); const viewports [ { name: Desktop, width: 1920, height: 1080 }, { name: Laptop, width: 1366, height: 768 }, { name: Tablet, width: 768, height: 1024 }, { name: Mobile, width: 375, height: 667 } ]; for (const viewport of viewports) { await page.setViewportSize(viewport); await page.goto(url, { waitUntil: networkidle }); await validateLayout(page, viewport.name); await takeScreenshot(page, ${viewport.name.toLowerCase()}.png); } await browser.close(); }表单自动化测试需要处理复杂的验证逻辑和动态字段。Playwright-Skill提供了智能表单填充和验证机制// 复杂表单测试策略 async function testComplexForm(formConfig) { const { page, formSelector, testData } formConfig; const elementMap { text: async (locator, value) await locator.fill(value), select: async (locator, value) await locator.selectOption(value), checkbox: async (locator, checked) checked ? await locator.check() : await locator.uncheck(), radio: async (locator) await locator.check() }; for (const field of testData.fields) { const locator page.locator(field.selector); const handler elementMap[field.type]; if (handler) { await handler(locator, field.value); if (field.validation) { await validateField(locator, field.validation); } } } await page.click(formConfig.submitSelector); await validateSubmissionResult(page, testData.expectedOutcome); }高级测试模式实现原理网络请求拦截与模拟是测试复杂应用的关键能力。Playwright-Skill提供了完整的请求/响应控制机制// 网络请求控制策略 async function setupNetworkInterception(page) { await page.route(**/api/**, async (route) { const url route.request().url(); if (url.includes(/api/users)) { return route.fulfill({ status: 200, contentType: application/json, body: JSON.stringify([ { id: 1, name: 模拟用户1 }, { id: 2, name: 模拟用户2 } ]) }); } await route.continue(); }); await page.route(**/*.{png,jpg,jpeg,gif,svg}, (route) route.abort()); await page.route(**/*, (route) { const headers route.request().headers(); headers[X-Test-Environment] automation; route.continue({ headers }); }); }并行测试执行优化通过浏览器上下文隔离技术实现测试用例的并行执行显著提升测试效率// 并行测试执行架构 async function runParallelTests(testSuites) { const browser await chromium.launch(); const contexts []; const results []; for (let i 0; i Math.min(testSuites.length, 4); i) { contexts.push(await browser.newContext()); } const promises testSuites.map(async (suite, index) { const context contexts[index % contexts.length]; const page await context.newPage(); try { const result await executeTestSuite(page, suite); results.push({ suite: suite.name, result }); } catch (error) { results.push({ suite: suite.name, error: error.message }); } }); await Promise.all(promises); await browser.close(); return results; }扩展应用企业级自动化测试架构设计持续集成与自动化测试流水线将Playwright-Skill集成到CI/CD流水线中可以实现代码提交后的自动验证。以下是一个完整的GitHub Actions配置示例name: Playwright-Skill Automated Testing on: push: branches: [main, develop] pull_request: branches: [main] jobs: playwright-tests: runs-on: ubuntu-latest strategy: matrix: node-version: [18.x, 20.x] steps: - uses: actions/checkoutv3 - name: Setup Node.js ${{ matrix.node-version }} uses: actions/setup-nodev3 with: node-version: ${{ matrix.node-version }} - name: Install Playwright-Skill run: | git clone https://gitcode.com/gh_mirrors/pl/playwright-skill.git /tmp/playwright-skill mkdir -p .claude/skills cp -r /tmp/playwright-skill/skills/playwright-skill .claude/skills/ cd .claude/skills/playwright-skill npm run setup - name: Generate and Execute Tests run: | cd .claude/skills/playwright-skill node generate-tests.js --commit-message ${{ github.event.head_commit.message }} find /tmp/playwright-test-*.js -exec node run.js {} \;

}); metrics.paintMetrics paint; return metrics; }安全测试与漏洞扫描架构扩展Playwright-Skill的安全测试能力实现自动化安全漏洞扫描// 安全测试套件 class SecurityTestSuite { constructor(page) { this.page page; this.vulnerabilities []; } async testXSSVulnerability() { const xssPayloads [ scriptalert(XSS)/script, img srcx onerroralert(1), javascript:alert(document.cookie) ]; for (const payload of xssPayloads) { const url ${this.page.url()}?input${encodeURIComponent(payload)}; await this.page.goto(url); const hasAlert await this.page.evaluate(() { return typeof window.alertCalled ! undefined; }); if (hasAlert) { this.vulnerabilities.push({ type: XSS, payload, severity: HIGH }); } } } async testCSRFVulnerability() { const response await this.page.request.post(/api/sensitive-action, { headers: { Content-Type: application/json }, data: { action: delete } }); if (response.status() 200) { const hasCsrfProtection await this.page.evaluate(() { const meta document.querySelector(meta[namecsrf-token]); return !!meta; }); if (!hasCsrfProtection) { this.vulnerabilities.push({ type: CSRF, description: 缺少CSRF令牌保护, severity: MEDIUM }); } } } async testInformationDisclosure() { const sensitivePatterns [ /password/i, /secret/i, /api[_-]?key/i, /token/i, /私钥/i, /密钥/i ]; const pageContent await this.page.content(); const sourceCode await this.page.evaluate(() document.documentElement.outerHTML); for (const pattern of sensitivePatterns) { if (pattern.test(pageContent) || pattern.test(sourceCode)) { this.vulnerabilities.push({ type: Information Disclosure, pattern: pattern.toString(), severity: HIGH }); } } } }技术架构演进与最佳实践微服务架构下的分布式测试设计在微服务架构中Playwright-Skill可以扩展为分布式测试系统支持多环境、多服务的集成测试// 分布式测试协调器 class DistributedTestCoordinator { constructor(config) { this.config config; this.workers []; this.results new Map(); } async distributeTests(testSuites) { const groupedSuites this.groupByComplexity(testSuites); for (let i 0; i this.config.workerCount; i) { const worker new TestWorker(i, this.config); this.workers.push(worker); await worker.initialize(); } const assignments this.assignTestsToWorkers(groupedSuites); const promises assignments.map(async (assignment, index) { const worker this.workers[index % this.workers.length]; const result await worker.executeTests(assignment); this.results.set(worker.id, result); }); await Promise.all(promises); return this.aggregateResults(); } }机器学习驱动的测试优化架构通过机器学习算法分析测试执行数据优化测试策略和执行顺序// 智能测试优化器 class IntelligentTestOptimizer { constructor(historicalData) { this.historicalData historicalData; this.model this.trainModel(); } trainModel() { return { predictOptimalOrder: (tests) { return tests.sort((a, b) { const scoreA this.calculateTestScore(a); const scoreB this.calculateTestScore(b); return scoreB - scoreA; }); }, suggestTestReduction: (tests) { return tests.filter(test this.calculateTestValue(test) this.config.minValueThreshold ); } }; } calculateTestScore(test) { const weights { failureRate: 0.4, executionTime: 0.3, codeCoverage: 0.2, recentChanges: 0.1 }; const history this.historicalData.get(test.id) || {}; const score (1 - (history.failureRate || 0)) * weights.failureRate (1 - Math.min(history.executionTime || 0, 10) / 10) * weights.executionTime (history.codeCoverage || 0) * weights.codeCoverage (history.recentChanges || 0) * weights.recentChanges; return score; } }性能基准测试与回归检测系统建立性能基准线自动检测性能回归// 性能基准测试系统 class PerformanceBenchmarkSystem { constructor(baselineData) { this.baseline baselineData; this.thresholds { regression: 0.2, improvement: 0.1, variance: 0.05 };
