5.2 急诊预警场景

// src/main/java/com/huawei/medical/scenes/EmergencyAlertScene.java
public class EmergencyAlertScene {

}

六、测试与验证

6.1 医疗数据同步测试

// src/test/java/com/huawei/medical/DeviceSyncTest.java
public class DeviceSyncTest {
    private DeviceManager deviceManager;
    private MockMedicalDevice mockDevice;
    
    @Before
    public void setUp() {
        deviceManager = new DeviceManager(context);
        mockDevice = new MockBloodPressureMonitor();
    }
    
    @Test
    public void testBloodPressureDataSync() {
        // 模拟血压数据
        List<HealthData> testData = Arrays.asList(
            new HealthData("blood_pressure", "128/82", "mmHg", new Date()),
            new HealthData("heart_rate", "72", "bpm", new Date()),
            new HealthData("blood_oxygen", "98", "%", new Date())
        );
        
        mockDevice.setTestData(testData);
        
        // 连接设备
        MedicalDevice device = deviceManager.connectDevice(mockDevice, ConnectionConfig.getDefault());
        
        // 同步数据
        DeviceSyncResult result = deviceManager.syncDeviceData(device, SyncConfig.getDefault());
        
        // 验证同步结果
        assertEquals("应同步3条记录", 3, result.getSyncedRecords().size());
        assertTrue("数据应包含血压读数", 
            result.getSyncedRecords().stream()
                .anyMatch(data -> "blood_pressure".equals(data.getType())));
    }
    
    @Test
    public void testDataValidation() {
        // 测试异常数据验证
        HealthData invalidData = new HealthData("blood_pressure", "300/200", "mmHg", new Date());
        
        try {
            HealthDataValidator.validate(invalidData);
            fail("应拒绝异常血压读数");
        } catch (ValidationException e) {
            // 预期异常
            assertTrue("应提示数据范围异常", e.getMessage().contains("范围"));
        }
    }
}

6.2 电子病历安全测试

// src/test/java/com/huawei/medical/RecordSecurityTest.java
public class RecordSecurityTest {
    private ElectronicRecordService recordService;
    private MockUser unauthorizedUser;
    
    @Test
    public void testRecordAccessControl() {
        // 创建测试病历
        MedicalRecord testRecord = createTestRecord();
        recordService.createRecord(testRecord, authorizedContext);
        
        // 尝试未授权访问
        try {
            recordService.getRecord(testRecord.getRecordId(), unauthorizedContext);
            fail("应拒绝未授权访问");
        } catch (RecordAccessException e) {
            // 预期异常
            assertTrue("应提示权限不足", e.getMessage().contains("权限"));
        }
    }
    
    @Test
    public void testDataEncryption() {
        MedicalRecord record = createSensitiveRecord();
        MedicalRecord savedRecord = recordService.createRecord(record, authorizedContext);
        
        // 验证数据加密
        String storedData = getStoredRecordData(savedRecord.getRecordId());
        assertFalse("敏感数据应加密存储", 
            storedData.contains(record.getSensitiveInformation()));
    }
}
