appium+pyton-定位toast

toast要appium1.6.3以上版本才支持，appium1.4的版本就别浪费时间了
Supported Platforms

1.查看appium v1.7版本官方文档

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.从上面的信息可以看出目前1.7的android版可以支持：Espresso、UiAutomator2、UiAutomator、Selendroid四种驱动模式，后面两个不推荐用了，太老了，Espresso这个是最新支持的处于beta阶段，UiAutomator2是目前最稳的。

3.appium最新版本还能支持windows和mac的桌面app程序了，这个是否稳定，拭目以待！
toast定位

1.先看下toast长什么样，如下图，像这种弹出来的消息"再按一次退出",这种就是toast了。

2.想定位toast元素，这里一定要注意automationName的参数必须是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)

等主页面activity出现

driver.wait_activity(".base.ui.MainActivity", 10)

driver.back() # 点返回

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.打印出来的结果，出现如下信息，说明定位到toast了

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

封装toast判断

1.单独写一个函数来封装判断是否存在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 - 传driver
- text - 页面上看到的文本内容
- timeout - 最大超时时间，默认30s
- poll_frequency - 间隔查询时间，默认0.5s查询一次
:Usage:
is_toast_exist(driver, “看到的内容”)
‘’’
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

参考代码

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 - 传driver
- text - 页面上看到的文本内容
- timeout - 最大超时时间，默认30s
- poll_frequency - 间隔查询时间，默认0.5s查询一次
:Usage:
is_toast_exist(driver, “看到的内容”)
‘’’
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)

# 等主页面activity出现
driver.wait_activity(".base.ui.MainActivity", 10)

driver.back()   # 点返回

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