Appium脚本(2)：元素检测

场景：

　　有的按钮在第一次打开时显示，之后就不显示了，如更新提示、特性介绍等，面对这样的场景写了如下脚本，增加脚本的复用性。

no_element_exception_2.py

 from appium import webdriver
 from selenium.common.exceptions import NoSuchElementException

 desired_caps = {}
 desired_caps['platformName'] = 'Android'
 desired_caps['deviceName'] = '127.0.0.1:62001'
 desired_caps['platforVersion'] = '5.1.1'

 # 真机配置
 # desired_caps['deviceName']='MX4'
 # desired_caps['platforVersion']='5.1'
 # desired_caps['udid']='750BBKL22GDN'

 # desired_caps['app'] = r'C:\python_dir\apps\kaoyan3.1.0.apk'
 desired_caps['appPackage'] = 'com.tal.kaoyan'
 desired_caps['appActivity'] = 'com.tal.kaoyan.ui.activity.SplashActivity'

 # 重置开关，默认false，默认每次如第一次安装好的状态
 desired_caps['noReset'] = 'True'

 driver = webdriver.Remote('http://localhost:4723/wd/hub', desired_caps)
 driver.implicitly_wait(5)

 def check_cancelBtn():
     print("check cancel button")
     try:
         cancelBtn = driver.find_element_by_id('android:id/button2')
     except NoSuchElementException:
         print("no cancel button")
     else:
         cancelBtn.click()
         driver.implicitly_wait(2)

 def check_skipBtn():
     print("check skip button")
     try:
         skipBtn = driver.find_element_by_id('com.tal.kaoyan:id/tv_skip')
     except NoSuchElementException:
         print("no skip button")
     else:
         skipBtn.click()
         driver.implicitly_wait(2)

 check_cancelBtn()
 check_skipBtn()
 driver.find_element_by_id('com.tal.kaoyan:id/login_register_text').click()
 driver.implicitly_wait(5)
