// 测试响应式布局 const element = await driver.findElement(By.css('.responsive-element')); const isVisible = await element.isDisplayed(); console.log(`Screen ${size.width}x${size.height}: Element visible: ${isVisible}`);}2. 测试横竖屏切换// 测试横竖屏切换async function testOrientation() { // 竖屏模式 await driver.rotateScreen('PORTRAIT'); const portraitElement = await driver.findElement(By.css('.portrait-element')); const portraitVisible = await portraitElement.isDisplayed(); console.log('Portrait mode:', portraitVisible); // 横屏模式 await driver.rotateScreen('LANDSCAPE'); const landscapeElement = await driver.findElement(By.css('.landscape-element')); const landscapeVisible = await landscapeElement.isDisplayed(); console.log('Landscape mode:', landscapeVisible);}await testOrientation();性能测试1. 页面加载时间// 测量页面加载时间async function measurePageLoadTime(driver, url) { const startTime = Date.now(); await driver.get(url); const endTime = Date.now(); const loadTime = endTime - startTime; console.log(`Page load time: ${loadTime}ms`); return loadTime;}const loadTime = await measurePageLoadTime(driver, 'https://example.com');assert(loadTime < 3000, 'Page load time should be less than 3 seconds');2. 资源加载时间// 获取性能指标const metrics = await driver.executeScript(` return window.performance.timing;`);const pageLoadTime = metrics.loadEventEnd - metrics.navigationStart;const domContentLoaded = metrics.domContentLoadedEventEnd - metrics.navigationStart;console.log('Page load time:', pageLoadTime);console.log('DOM content loaded:', domContentLoaded);3. 网络性能// 使用 Chrome DevTools Protocolconst performance = await driver.getPerformanceMetrics();console.log('Performance metrics:', performance);// 获取网络日志const logs = await driver.manage().logs().get('performance');console.log('Network logs:', logs);跨浏览器测试1. 多浏览器测试// 测试多个浏览器const browsers = [ { browserName: 'Chrome', platformName: 'Android' }, { browserName: 'Safari', platformName: 'iOS' }];for (const browser of browsers) { const capabilities = { ...browser, deviceName: 'Test Device', platformVersion: 'latest' }; const driver = await new Builder() .withCapabilities(capabilities) .build(); try { await driver.get('https://example.com'); // 执行测试 } finally { await driver.quit(); }}2. 浏览器兼容性测试// 测试浏览器兼容性async function testBrowserCompatibility(driver, url) { await driver.get(url); // 检查元素是否正确显示 const element = await driver.findElement(By.id('main-content')); const isVisible = await element.isDisplayed(); assert(isVisible, 'Element should be visible'); // 检查样式是否正确 const backgroundColor = await element.getCssValue('background-color'); console.log('Background color:', backgroundColor); // 检查交互是否正常 const button = await driver.findElement(By.id('submit_button')); await button.click(); const result = await driver.findElement(By.id('result_message')); const text = await result.getText(); assert.strictEqual(text, 'Success');}移动端特定功能测试1. 触摸手势测试// 测试触摸手势async function testTouchGestures(driver) { // 测试点击 const element = await driver.findElement(By.id('button')); await element.click(); // 测试滑动 const size = await driver.manage().window().getRect(); await driver.touchActions([ { action: 'press', x: size.width / 2, y: size.height * 0.8 }, { action: 'moveTo', x: size.width / 2, y: size.height * 0.2 }, { action: 'release' } ]);

const landscapeElement = await driver.findElement(By.css('.landscape-only')); const landscapeVisible = await landscapeElement.isDisplayed(); console.log('Landscape element visible:', landscapeVisible);}3. 网络状态测试// 测试网络状态async function testNetworkConditions(driver) { // 设置网络速度 await driver.setNetworkConditions({ offline: false, latency: 100, // 100ms 延迟 download_throughput: 500 * 1024, // 500KB/s upload_throughput: 500 * 1024 // 500KB/s }); // 测试页面加载 const startTime = Date.now(); await driver.get('https://example.com'); const loadTime = Date.now() - startTime; console.log('Load time with slow network:', loadTime); // 恢复正常网络 await driver.setNetworkConditions({ offline: false, latency: 0, download_throughput: -1, upload_throughput: -1 });}最佳实践1. 使用 Page Object 模式// Page Object 模式class MobileWebPage { constructor(driver) { this.driver = driver; } async open(url) { await this.driver.get(url); } async fillForm(data) { for (const [key, value] of Object.entries(data)) { const input = await this.driver.findElement(By.id(key)); await input.clear(); await input.sendKeys(value); } } async submit() { const button = await this.driver.findElement(By.id('submit_button')); await button.click(); } async getResult() { const result = await this.driver.findElement(By.id('result_message')); return await result.getText(); }}// 使用 Page Objectconst page = new MobileWebPage(driver);await page.open('https://example.com');await page.fillForm({ username: 'test', password: 'password' });await page.submit();const result = await page.getResult();2. 响应式测试// 响应式测试套件async function runResponsiveTests(driver) { const screenSizes = [ { name: 'Mobile', width: 375, height: 667 }, { name: 'Tablet', width: 768, height: 1024 }, { name: 'Desktop', width: 1920, height: 1080 } ]; for (const size of screenSizes) { console.log(`Testing on ${size.name} (${size.width}x${size.height})`); await driver.manage().window().setRect({ width: size.width, height: size.height }); // 执行测试 await testResponsiveLayout(driver); }}3. 性能监控// 性能监控async function monitorPerformance(driver) { const metrics = await driver.executeScript(` return { loadTime: window.performance.timing.loadEventEnd - window.performance.timing.navigationStart, domContentLoaded: window.performance.timing.domContentLoadedEventEnd - window.performance.timing.navigationStart, firstPaint: window.performance.timing.responseStart - window.performance.timing.navigationStart }; `); console.log('Performance metrics:', metrics); // 验证性能指标 assert(metrics.loadTime < 3000, 'Page load time should be less than 3 seconds'); assert(metrics.domContentLoaded < 1500, 'DOM content loaded should be less than 1.5 seconds');}常见问题1. 浏览器启动失败问题：无法启动浏览器解决方案：// 检查浏览器是否安装// Android: 检查 Chrome 是否安装// iOS: 检查 Safari 是否可用// 使用正确的 browserNameconst capabilities = { platformName: 'Android', browserName: 'Chrome', // 确保浏览器名称正确 deviceName: 'Pixel 5'};2. 元素定位失败问题：无法定位元素解决方案：// 等待元素加载const element = await driver.wait( until.elementLocated(By.id('submit_button')), 10000);// 检查元素是否在视口中await driver.executeScript('arguments[0].scrollIntoView(true);', element);// 使用更精确的定位策略const element = await driver.findElement(By.css('#submit_button.btn-primary'));3. 触摸操作不响应问题：触摸操作没有响应解决方案：// 使用 JavaScript 点击await driver.executeScript('arguments[0].click();', element);// 使用坐标点击const rect = await element.getRect();const x = rect.x + rect.width / 2;const y = rect.y + rect.height / 2;await driver.touchActions([{ action: 'tap', x: x, y: y }]);Appium 的移动 Web 测试为测试人员提供了强大的移动浏览器自动化能力，通过合理的测试策略和最佳实践，可以构建全面、可靠的移动 Web 测试。
