<DirectionalLayout
xmlns:ohos=“http://schemas.huawei.com/res/ohos”
ohos:width=“match_parent”
ohos:height=“match_parent”
ohos:orientation=“vertical”
ohos:padding=“24vp”>
<Text
ohos:width="match_parent"
ohos:height="wrap_content"
ohos:text="系统版本兼容性测试"
ohos:text_size="32fp"
ohos:margin_bottom="24vp"/>
<Button
ohos:id="$+id/start_discovery"
ohos:width="match_parent"
ohos:height="60vp"
ohos:text="开始发现设备"
ohos:margin_bottom="16vp"/>
<ScrollView
ohos:width="match_parent"
ohos:height="0vp"
ohos:weight="1">

ohos:height="match_content"/>
</ScrollView>
<Button
ohos:id="$+id/start_test"
ohos:width="match_parent"
ohos:height="60vp"
ohos:text="开始兼容性测试"
ohos:visibility="hide"
ohos:margin_top="16vp"/>
</DirectionalLayout>
<!-- 报告布局 report_layout.xml -->
<DirectionalLayout
xmlns:ohos=“http://schemas.huawei.com/res/ohos”
ohos:width=“match_parent”
ohos:height=“match_parent”
ohos:orientation=“vertical”>
<WebView
ohos:id="$+id/report_webview"
ohos:width="match_parent"
ohos:height="0vp"
ohos:weight="1"/>
<Button
ohos:id="$+id/export_btn"
ohos:width="match_parent"
ohos:height="60vp"

五、技术创新点
自动化测试：一键完成多设备兼容性测试
全面覆盖：验证分布式数据同步、跨设备调用等核心功能
可视化报告：生成直观的兼容性矩阵HTML报告
版本感知：自动识别设备系统版本和API级别
分布式协调：借鉴游戏同步机制实现多设备测试协调
六、总结
本系统版本兼容性矩阵验证工具实现了以下核心价值：
质量保障：确保功能在不同系统版本上的兼容性
效率提升：自动化测试流程节省人工测试时间
问题预防：提前发现潜在的版本兼容性问题
决策支持：为版本升级和设备支持提供数据依据
标准化流程：建立统一的兼容性测试方法
系统借鉴了《鸿蒙跨端U同步》中的设备协同与状态同步技术，将游戏场景的多设备协调机制应用于兼容性测试领域。未来可增加更多测试用例，并与CI/CD流程集成实现自动化兼容性验证。
