一、appium工做原理

1. 啓動appium server
2. appium client 發送Desired Capabilities信息給appium server，appium server返回一個session id給client
3. appium client發送指令給appium server，appium server把命令發送到移動設備上去執行
4. 移動端設備將執行結果返回給appium server，appium server再返回給client

desired capabilities

desired capabilities是什麼，它的做用是告訴appium server被測試apk相關的信息，移動設備相關的信息。直接上官網的解釋，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.

二、準備工做

• 啓動安卓模擬器，並打開開發者模式
• 啓動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

• 下載錘子日曆apk，v1.6
  下載地址：http://www.paopaoche.net/android/77944.html

• 查看模擬器是否鏈接成功

adb devices

若是設備未鏈接，嘗試手動鏈接

#夜神模擬器鏈接命令
adb connect 127.0.0.1:62001

# 逍遙模擬器
adb connect 127.0.0.1:21503

三、第一個appium腳本

在模擬器上安裝錘子日曆並啓動。

獲取包名和啓動的activity

aapt dump    badging  C:\appium\chuizirili_ppc.apk

編寫腳本

from time import sleep
#從appium中導入webdriver
from appium import  webdriver


desired_apability = {}
#平臺名稱：Android/IOS
desired_apability["platformName"] = "Android"
#系統版本
desired_apability["platformVersion"] ="4.4.2"
#設備名稱
desired_apability["deviceName"] = "127.0.0.1:62001"
#是否重置會話
desired_apability["noReset"] = True
#啓動的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()

運行結果

運行腳本，打開模擬器觀察效果，
