appium+pyton-定位toast

toast要appium1.6.3以上版本才支持，appium1.4的版本就別浪費時間了
Supported Platforms

1.查看appium v1.7版本官方文檔

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長什麼樣，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，這裏一定要注意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 selenium.webdriver.support.ui import WebDriverWait

desired_caps = {

‘deviceName’: ‘127.0.0.1:62001’,

‘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:

:Usage:

‘’’
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")
