Golang-UIAutomator2

使用 Golang 实现 appium/appium-uiautomator2-server 的客户端库

扩展库

• electricbubble/guia2-ext-opencv 直接通过指定图片进行操作

如果使用 IOS 设备, 可查看 electricbubble/gwda

安装

go get github.com/electricbubble/guia2

使用

首次使用需要在 Android 设备中安装两个 apk
appium-uiautomator2-server-debug-androidTest.apk
appium-uiautomator2-server-vXX.XX.XX.apk

apk 可以选择通过 appium/appium-uiautomator2-server 进行构建
也可以直接从这里下载 electricbubble/appium-uiautomator2-server-apk

再通过 adb 启动 appium-uiautomator2-server

adb shell am instrument -w io.appium.uiautomator2.server.test/androidx.test.runner.AndroidJUnitRunner
# ⬇️ 后台运行
adb shell "nohup am instrument -w io.appium.uiautomator2.server.test/androidx.test.runner.AndroidJUnitRunner >/sdcard/uia2server.log 2>&1 &"
# or
adb -s $serial shell "nohup am instrument -w io.appium.uiautomator2.server.test/androidx.test.runner.AndroidJUnitRunner >/sdcard/uia2server.log 2>&1 &"

guia2.NewUSBDriver()

该函数使用期间, Android 设备必须一直保持 USB 的连接 (模拟器 也使用该函数)

guia2.NewWiFiDriver("192.168.1.28")

1. 先通过 USB 连接 Android 设备
2. 让设备在 5555 端口监听 TCP/IP 连接

   adb tcpip 5555
   # or
   adb -s $serial tcpip 5555

3. 查询 Android 设备的 IP (这一步骤开始可选择断开 USB 连接)
4. 通过 IP 连接 Android 设备

   adb connect $deviceIP

5. 确认连接状态

   adb devices

   看到以下格式的设备, 说明连接成功

   $deviceIP:5555    device
