跨设备FA启动速度测试工具设计与实现
一、项目概述
基于HarmonyOS分布式能力构建的跨设备FA（Feature Ability）启动速度测试工具，可测量同一FA在不同设备上的启动耗时，并分析性能差异。借鉴《鸿蒙跨端U同步》中的设备协同机制，实现多设备测试任务的同步执行与结果收集。

三、核心代码实现
测试控制端实现
// 测试控制端Ability
public class TestControllerAbility extends Ability {
private static final String TAG = “TestController”;
private DistributedScheduler scheduler;
private List<DeviceInfo> testDevices = new ArrayList<>();
private Map<String, TestResult> results = new ConcurrentHashMap<>();
@Override
public void onStart(Intent intent) {
super.onStart(intent);
setUIContent(ResourceTable.Layout_controller_layout);
// 初始化分布式调度器
scheduler = DistributedScheduler.getInstance(this);
// 获取可用设备列表
discoverDevices();
// 设置测试按钮点击事件
findComponentById(ResourceTable.Id_start_test).setClickedListener(component -> {
startTestOnAllDevices();
});
// 发现周边设备
private void discoverDevices() {
DeviceManager deviceManager = DeviceManager.getInstance(this);
deviceManager.discoverDevices(new DeviceDiscoveryCallback() {
@Override
public void onDeviceFound(DeviceInfo device) {
if (device.getDeviceType() != DeviceType.PHONE) return;
getUITaskDispatcher().asyncDispatch(() -> {
testDevices.add(device);
updateDeviceListUI();
});
@Override
public void onDiscoveryFailed(int errorCode) {
HiLog.error(TAG, "Device discovery failed: " + errorCode);
});
// 在所有设备上启动测试
private void startTestOnAllDevices() {
String testAbility = "com.example.testfa.MainAbility";
String bundleName = "com.example.testfa";
for (DeviceInfo device : testDevices) {
TestTask task = new TestTask();
task.setTargetAbility(testAbility);
task.setBundleName(bundleName);
task.setDeviceId(device.getDeviceId());
scheduler.executeTask(device.getDeviceId(), task, new TestCallback());
}
// 测试任务类
public static class TestTask extends DistributedScheduler.BaseTask {
private String targetAbility;
private String bundleName;
// Getters & Setters
public String getTargetAbility() { return targetAbility; }
public void setTargetAbility(String targetAbility) { this.targetAbility = targetAbility; }
public String getBundleName() { return bundleName; }
public void setBundleName(String bundleName) { this.bundleName = bundleName; }
// 测试回调
private class TestCallback implements DistributedScheduler.TaskCallback {
@Override
public void onSuccess(String deviceId, DistributedScheduler.BaseTask task) {
TestResult result = (TestResult) task;
results.put(deviceId, result);
getUITaskDispatcher().asyncDispatch(() -> {
updateResultsUI();
});
@Override
public void onFailure(String deviceId, int errorCode) {
HiLog.error(TAG, "Test failed on device " + deviceId + ", error: " + errorCode);
}
// 更新UI显示测试结果
private void updateResultsUI() {
// 实现结果可视化展示
}
测试执行端实现
// 测试执行端Ability
public class TestExecutorAbility extends Ability {
private static final String TAG = “TestExecutor”;
private DistributedScheduler scheduler;
@Override
public void onStart(Intent intent) {
super.onStart(intent);
// 注册测试任务处理器
scheduler = DistributedScheduler.getInstance(this);
scheduler.registerTaskHandler(TestControllerAbility.TestTask.class, new TestHandler());
// 测试任务处理器
private class TestHandler implements DistributedScheduler.TaskHandler {
@Override
public DistributedScheduler.BaseTask onExecute(String deviceId, DistributedScheduler.BaseTask task) {
TestControllerAbility.TestTask testTask = (TestControllerAbility.TestTask) task;
// 记录开始时间
long startTime = System.currentTimeMillis();
// 启动目标FA
Intent intent = new Intent();
Operation operation = new Intent.OperationBuilder()
.withDeviceId("")
.withBundleName(testTask.getBundleName())
.withAbilityName(testTask.getTargetAbility())
.build();
intent.setOperation(operation);
startAbility(intent);
// 记录结束时间
long endTime = System.currentTimeMillis();
long duration = endTime - startTime;
// 返回测试结果
TestResult result = new TestResult();
result.setDuration(duration);
result.setDeviceId(deviceId);
result.setSuccess(true);
return result;
}
// 测试结果类
public static class TestResult extends DistributedScheduler.BaseTask {
private long duration;
private boolean success;
// Getters & Setters
public long getDuration() { return duration; }
public void setDuration(long duration) { this.duration = duration; }
public boolean isSuccess() { return success; }
public void setSuccess(boolean success) { this.success = success; }
}
分布式任务调度服务
// 分布式任务调度服务
public class DistributedScheduler {
private static final String SCHEDULER_CHANNEL = “test_scheduler”;
private static DistributedScheduler instance;
private DistributedDataManager dataManager;
private Map<Class<?>, TaskHandler> handlers = new ConcurrentHashMap<>();
private DistributedScheduler(Context context) {
this.dataManager = DistributedDataManagerFactory.getInstance()
.createDistributedDataManager(context);
public static synchronized DistributedScheduler getInstance(Context context) {
if (instance == null) {
instance = new DistributedScheduler(context);
return instance;
// 注册任务处理器
public <T extends BaseTask> void registerTaskHandler(Class<T> taskClass, TaskHandler handler) {
handlers.put(taskClass, handler);
// 监听任务请求
dataManager.registerDataChangeListener(SCHEDULER_CHANNEL, new DataChangeListener() {
@Override
public void onDataChanged(String deviceId, String key, String value) {
try {
JSONObject json = new JSONObject(value);
String taskType = json.getString("taskType");
Class<?> type = Class.forName(taskType);
TaskHandler handler = handlers.get(type);
if (handler != null) {
BaseTask task = (BaseTask) GsonUtils.fromJson(value, type);
BaseTask result = handler.onExecute(deviceId, task);
// 返回结果
dataManager.putString(SCHEDULER_CHANNEL + "_result",
GsonUtils.toJson(result));
} catch (Exception e) {
HiLog.error(TAG, "Task handling error: " + e.getMessage());
}
});
// 执行远程任务
public void executeTask(String deviceId, BaseTask task, TaskCallback callback) {
try {
JSONObject json = new JSONObject(GsonUtils.toJson(task));
json.put("taskType", task.getClass().getName());
dataManager.putString(SCHEDULER_CHANNEL, json.toString());
// 监听结果
dataManager.registerDataChangeListener(SCHEDULER_CHANNEL + "_result",
new DataChangeListener() {
@Override
public void onDataChanged(String senderId, String key, String value) {
BaseTask result = GsonUtils.fromJson(value, task.getClass());
callback.onSuccess(senderId, result);
dataManager.unregisterDataChangeListener(this);
});
catch (JSONException e) {
callback.onFailure(deviceId, -1);
}
// 基础任务类
public static abstract class BaseTask {
// 可添加公共字段
// 任务处理器接口
public interface TaskHandler {
BaseTask onExecute(String deviceId, BaseTask task);
// 任务回调接口
public interface TaskCallback {
void onSuccess(String deviceId, BaseTask task);
void onFailure(String deviceId, int errorCode);
}
测试结果可视化
// 测试结果展示AbilitySlice
public class ResultAnalysisSlice extends AbilitySlice {
private Map<String, TestExecutorAbility.TestResult> results;
private BarChartView chartView;
@Override
public void onStart(Intent intent) {
super.onStart(intent);
setUIContent(ResourceTable.Layout_result_layout);
// 获取测试结果
results = intent.getSerializableParam("results");
// 初始化图表
chartView = (BarChartView) findComponentById(ResourceTable.Id_result_chart);
displayResults();
private void displayResults() {
List<BarChartView.BarData> bars = new ArrayList<>();
for (Map.Entry<String, TestExecutorAbility.TestResult> entry : results.entrySet()) {
String deviceName = DeviceInfo.getDeviceName(entry.getKey());
long duration = entry.getValue().getDuration();
BarChartView.BarData bar = new BarChartView.BarData();
bar.setLabel(deviceName);
bar.setValue(duration);
bar.setColor(getDeviceColor(entry.getKey()));
bars.add(bar);
chartView.setData(bars);
chartView.setYAxisLabel("启动时间(ms)");
chartView.startAnimation();
private int getDeviceColor(String deviceId) {
// 为不同设备分配不同颜色
int hash = deviceId.hashCode();
return Color.rgb(
(hash & 0xFF0000) >> 16,
(hash & 0x00FF00) >> 8,
hash & 0x0000FF
);
}
四、XML布局示例
<!-- 控制器布局 controller_layout.xml -->
<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:id="$+id/title"
ohos:width="match_parent"
ohos:height="wrap_content"
ohos:text="跨设备FA启动测试"
ohos:text_size="32fp"
ohos:margin_bottom="24vp"/>
<ScrollView
ohos:width="match_parent"
ohos:height="0vp"
ohos:weight="1">
<ListContainer
ohos:id="$+id/device_list"
ohos:width="match_parent"
ohos:height="match_content"/>
</ScrollView>
<Button
ohos:id="$+id/start_test"
ohos:width="match_parent"
ohos:height="60vp"
ohos:text="开始测试"
ohos:margin_top="24vp"/>
</DirectionalLayout>
<!-- 结果布局 result_layout.xml -->
<DirectionalLayout
xmlns:ohos=“http://schemas.huawei.com/res/ohos”
ohos:width=“match_parent”
ohos:height=“match_parent”
ohos:orientation=“vertical”
ohos:padding=“24vp”>
<Text
ohos:width="match_parent"
ohos:height="wrap_content"
ohos:text="测试结果对比"
ohos:text_size="28fp"
ohos:margin_bottom="24vp"/>
<com.example.testtool.BarChartView
ohos:id="$+id/result_chart"
ohos:width="match_parent"
ohos:height="0vp"
ohos:weight="1"/>
<TableLayout
ohos:id="$+id/result_table"
ohos:width="match_parent"
ohos:height="300vp"
ohos:margin_top="24vp"/>
</DirectionalLayout>
五、技术创新点
分布式测试：利用HarmonyOS分布式能力实现多设备并行测试
精确计时：测量从启动请求到Ability完全加载的精确时间
自动同步：借鉴游戏同步机制实现测试任务自动分发
可视化分析：直观展示不同设备的性能差异
灵活扩展：支持测试任意FA的启动性能
六、总结
本跨设备FA启动速度测试工具实现了以下核心价值：
性能评估：量化不同设备的FA启动性能差异
自动化测试：一键触发多设备并行测试
数据可视化：直观展示测试结果
问题定位：帮助发现性能瓶颈设备
标准化流程：建立统一的FA性能测试方法
系统借鉴了《鸿蒙跨端U同步》中的任务分发与结果收集机制，将游戏场景的同步技术应用于性能测试领域。未来可增加更多测试维度（内存占用、CPU使用率等），并与CI/CD流程集成实现自动化性能回归测试。HarmonyOS5
