1、appium工作原理

1. 启动appium server
2. appium client 发送Desired Capabilities信息给appium server，appium server返回一个session id给client
3. appium client发送指令给appium server，appium server把命令发送到移动设备上去执行
4. 移动端设备将执行结果返回给appium server，appium server再返回给client

desired capabilities

desired capabilities是什么，它的作用是告诉appium server被测试apk相关的信息，移动设备相关的信息。直接上官网的解释，地址：

https://github.com/appium/appium/blob/master/docs/en/writing-running-appium/caps.md

Desired Capabilities are keys and values encoded in a JSON object, sent by Appium clients to the server when a new automation session is requested. They tell the Appium drivers all kinds of important things about how you want your test to work. Each Appium client builds capabilities in a way specific to the client's language, but at the end of the day, they are sent over to Appium as JSON objects.

2、准备工作

• 启动安卓模拟器，并打开开发者模式
• 启动appium server

PS C:\Users\StephenWang> appium -a 127.0.0.1 -p 4723
[Appium] Welcome to Appium v1.13.0
[Appium] Non-default server args:
[Appium]   address: 127.0.0.1
[Appium] Appium REST http interface listener started on 127.0.0.1:4723

• 下载锤子日历apk，v1.6
  下载地址：http://www.paopaoche.net/android/77944.html

• 查看模拟器是否连接成功

adb devices

如果设备未连接，尝试手动连接

#夜神模拟器连接命令
adb connect 127.0.0.1:62001# 逍遥模拟器
adb connect 127.0.0.1:21503

3、第一个appium脚本

在模拟器上安装锤子日历并启动。

获取包名和启动的activity

从上面可知，package: name='com.smartisan.calendar' ，aunchable activity name='com.android.calendar.AllInOneActivity'

编写脚本

from time import sleep
#从appium中导入webdriver
from appium import  webdriverdesired_apability = {}
#平台名称：Android/IOS
desired_apability["platformName"] = "Android"
#系统版本
desired_apability["platformVersion"] ="4.4.2"
#设备名称
desired_apability["deviceName"] = "127.0.0.1:62001"
#是否重置会话
desired_apability["noReset"] = True
#启动的Activity
desired_apability["appActivity"] = "com.android.calendar.AllInOneActivity"
#包名
desired_apability["appPackage"] = "com.smartisan.calendar"
#apk的地址
desired_apability["app"] = r"C:\appium\chuizirili_ppc.apk"driver = webdriver.Remote("http://127.0.0.1:4723/wd/hub",desired_apability)#睡眠5s
sleep(5)
print("Install  %s and start sucess" %desired_apability["appPackage"])
driver.quit()

运行结果

运行脚本，打开模拟器观察效果，
