移动App兼容性测试：覆盖千款设备的实战经验_千锋教育

设备优先级 = 用户占比 × 系统版本占比 × 屏幕尺寸分布 × 崩溃率权重

# 设备优先级排序脚本示例
import pandas as pd

def prioritize_devices(user_data):
    # 计算每个设备的用户占比
    device_stats = user_data.groupby('device_model').agg(
        user_count=('user_id', 'nunique'),
        crash_rate=('is_crash', 'mean'),
        avg_os_version=('os_version', 'mean')
    ).reset_index()
    
    # 计算综合优先级分数
    device_stats['priority_score'] = (
        device_stats['user_count'] * 0.5 +
        (1 - device_stats['crash_rate']) * 0.3 +
        device_stats['avg_os_version'] * 0.2
    )
    
    # 按优先级排序
    return device_stats.sort_values('priority_score', ascending=False)
