命令开关wifi/bluetooth -- Android svc命令与自动化/压力测试

svc指令可用于电源控制, 无线业务控制(modem/wifi/nfc/bt, etc), 等等.

可以不适用按键,触控设备, 而通过使用svc命令实现这些模块的功能操作,比如wifi的开关:

svc wifi enable //打开wifi

svc wifi disable //关闭wifi

 

因此, 对于涉及到这些模块的自动化测试和压力测试, 都可以使用svc命令, 来解放双手.

svc位于/system/bin/svc

# which svc
/system/bin/svc

# svc help
Available commands:
    help          Show information about the subcommands
    power         Control the power manager
    data          Control mobile data connectivity
    wifi          Control the Wi-Fi manager
    usb           Control Usb state
    nfc           Control NFC functions
    feedback      Control feedback state
    ebensecure    Control ebensecure state
    opt           Control the operation monitor manager
    bluetooth     Control Bluetooth service

# svc wifi
Control the Wi-Fi manager

usage: svc wifi [enable|disable]
         Turn Wi-Fi on or off.

svc可用于power/data/wifi/usb/nfc/bt等的自动化测试和压力测试.

下面通过wifi开关/自动重连的压力测试举例说明svc的好用之处.

wifi开关/自动重连的压力测试脚本:

#!/bin/sh

count_success=0
count_err=0
while true
do
svc wifi disable
sleep 5
svc wifi enable
sleep 20
wlan_status=`wpa_cli -i wlan0 status`
tmp=${wlan_status#*wpa_state=}
wpa_state=${tmp:0:9}
echo "STA status is: $wpa_state"
if [ $wpa_state = "COMPLETED" ];then
count_success=$(($count_success+1))
else
count_err=$(($count_err+1))
fi
echo "====== SUCCESS: $count_success, FAIL: $count_err ========"
done
