Supported Platforms

Appium supports app automation across a variety of platforms, like iOS, Android, and Windows. Each platform is supported by one or more "drivers", which know how to automate that particular platform. Choose a driver below for specific information about how that driver works and how to set it up:

• iOS
• The XCUITest Driver
• (DEPRECATED) The UIAutomation Driver
• Android
• (BETA) The Espresso Driver
• The UiAutomator2 Driver
• (DEPRECATED) The UiAutomator Driver
• (DEPRECATED) The Selendroid Driver
• The Windows Driver (for Windows Desktop apps)
• The Mac Driver (for Mac Desktop apps)

2.從上面的信息可以看出目前1.7的android版可以支持：Espresso、UiAutomator2、UiAutomator、Selendroid四種驅動模式，後面兩個不推薦用了，太老了，Espresso這個是最新支持的處於beta階段，UiAutomator2是目前最穩的。

3.appium最新版本還能支持windows和mac的桌面app程序了，這個是否穩定，拭目以待！

toast定位

1.先看下toast長什麽樣，如下圖，像這種彈出來的消息"再按一次退出",這種就是toast了。

2.想定位toast元素，這裏一定要註意automationName的參數必須是Uiautomator2才能定位到。

‘automationName‘: ‘Uiautomator2‘

# coding:utf-8
from appium import webdriver
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC
from time import sleep

desired_caps = {
                'platformName': 'Android',
                'deviceName': '127.0.0.1:62001',
                'platformVersion': '4.4.2',
                'appPackage': 'com.baidu.yuedu',
                'appActivity': 'com.baidu.yuedu.splash.SplashActivity',
                'noReset': 'true',
                'automationName': 'Uiautomator2'
                }
driver = webdriver.Remote('http://127.0.0.1:4723/wd/hub', desired_caps)

# 等主頁面activity出現
driver.wait_activity(".base.ui.MainActivity", 10)

driver.back()   # 點返回

# 定位toast元素
toast_loc = ("xpath", ".//*[contains(@text,'再按一次退出')]")
t = WebDriverWait(driver, 10, 0.1).until(EC.presence_of_element_located(toast_loc))
print t
 

3.打印出來的結果，出現如下信息，說明定位到toast了

<appium.webdriver.webelement.WebElement (session="02813cce-9aaf-4754-a532-07ef7aebeb88", element="339f72c4-d2e0-4d98-8db0-69be741a3d1b")>

封裝toast判斷

1.單獨寫一個函數來封裝判斷是否存在toast消息，存在返回True,不存在返回False

def is_toast_exist(driver,text,timeout=30,poll_frequency=0.5):
    '''is toast exist, return True or False
    :Agrs:
     - driver - 傳driver
     - text   - 頁面上看到的文本內容
     - timeout - 最大超時時間，默認30s
     - poll_frequency  - 間隔查詢時間，默認0.5s查詢一次
    :Usage:
     is_toast_exist(driver, "看到的內容")
    '''
    try:
        toast_loc = ("xpath", ".//*[contains(@text,'%s')]"%text)
        WebDriverWait(driver, timeout, poll_frequency).until(EC.presence_of_element_located(toast_loc))
        return True
    except:
        return False

參考代碼

# coding:utf-8
from appium import webdriver
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC
desired_caps = {
                'platformName': 'Android',
                'deviceName': '127.0.0.1:62001',
                'platformVersion': '4.4.2',
                'appPackage': 'com.baidu.yuedu',
                'appActivity': 'com.baidu.yuedu.splash.SplashActivity',
                'noReset': 'true',
                'automationName': 'Uiautomator2'
                }

def is_toast_exist(driver,text,timeout=30,poll_frequency=0.5):
    '''is toast exist, return True or False
    :Agrs:
     - driver - 傳driver
     - text   - 頁面上看到的文本內容
     - timeout - 最大超時時間，默認30s
     - poll_frequency  - 間隔查詢時間，默認0.5s查詢一次
    :Usage:
     is_toast_exist(driver, "看到的內容")
    '''
    try:
        toast_loc = ("xpath", ".//*[contains(@text,'%s')]"%text)
        WebDriverWait(driver, timeout, poll_frequency).until(EC.presence_of_element_located(toast_loc))
        return True
    except:
        return False

if __name__ == "__main__":
    driver = webdriver.Remote('http://127.0.0.1:4723/wd/hub', desired_caps)

    # 等主頁面activity出現
    driver.wait_activity(".base.ui.MainActivity", 10)

    driver.back()   # 點返回

    # 判斷是否存在toast-'再按一次退出'
    print is_toast_exist(driver, "再按一次退出")
