startInputCompatibilityTest();
});
// 发现周边设备
private void discoverDevices() {

public void onDeviceFound(DeviceInfo device) {
if (device.getDeviceType() == DeviceType.PHONE ||
device.getDeviceType() == DeviceType.TABLET) {
getUITaskDispatcher().asyncDispatch(() -> {
testDevices.add(device);
updateDeviceListUI();
});
}
@Override

五、技术创新点
多设备输入同步：验证输入内容在跨设备场景下的同步一致性
全面测试覆盖：支持中英文、符号、长文本、emoji等多种输入场景
智能错误检测：自动识别内容不一致、编码错误等兼容性问题
性能监控：测量输入响应延迟等关键性能指标
可视化报告：直观展示各设备的兼容性情况
六、总结
本输入法兼容性测试工具实现了以下核心价值：
质量保障：确保输入法在不同设备上的兼容性和一致性
效率提升：自动化执行复杂的跨设备输入测试场景
问题预防：提前发现潜在的输入法兼容性问题
性能优化：识别输入延迟等性能瓶颈
标准规范：建立统一的输入法兼容性测试方法
系统借鉴了《鸿蒙跨端U同步》中的状态同步技术，将游戏场景的多设备协同机制应用于输入法测试领域。未来可增加更多测试维度（如语音输入、手写输入等），并与自动化测试平台集成实现持续兼容性验证。
