Appium 解决微信公众号、小程序切换 webview 后无法定位元素的问题

如何切换webview进入小程序请参考https://testerhome.com/topics/12003

脚本思路：

进入webview后会存在多个handle同Web页签一样，获取所有的handle，然后在遍历所有的handle，通过switch_to_window进行handle切换，当某个handle可以定位到我们需要定位的元素时，然后我们就可以进行之后的自动化操作了！

1. <code Courier New', monospace;line-height:18px;font-size:12px;color:rgb(68,68,68);border:none;">#coding=utf-8

2. from appium import webdriver

3. import time,os,re

4. from appium.webdriver.common.touch_action import TouchAction

5. desired_caps = {}

6. desired_caps['platformName'] = 'Android'

7. desired_caps['deviceName'] = 'Android001'

8. desired_caps['unicodeKeyboard'] = True

9. desired_caps["resetKeyboard"] = True

10. desired_caps["newCommandTimeout"]=30

11. desired_caps['fullReset'] = 'false'

12. desired_caps['appPackage'] = 'com.tencent.mm'

13. desired_caps['appActivity'] = 'com.tencent.mm.ui.LauncherUI'

14. desired_caps['recreateChromeDriverSessions'] = True

15. desired_caps['noReset'] = True

16. desired_caps['newCommandTimeout'] = 10

17. desired_caps['chromeOptions']={'androidProcess': 'com.tencent.mm:appbrand0'}

18. driver = webdriver.Remote(command_executor = 'http://127.0.0.1:4723/wd/hub',desired_capabilities = desired_caps)

19. time.sleep(2)

20. time.sleep(1)

21. driver.implicitly_wait(10)

22. driver.find_element_by_name('发现').click()

23. time.sleep(1)

24. driver.swipe(100,1200,100,900)

25. driver.find_element_by_name('小程序').click()

26. driver.find_element_by_name('美团外卖').click()

27. time.sleep(2)

28. contexts = driver.contexts

29. print contexts

30. time.sleep(2)

31. driver.switch_to.context('WEBVIEW_com.tencent.mm:appbrand0')

32. print '切换成功'

33. print driver.current_context

34. all_handles = driver.window_handles

35. print len(all_handles)

36. for handle in all_handles:

37. try:

38. driver.switch_to_window(handle)

39. print driver.page_source

40. driver.find_element_by_css_selector('.filter-select.flex-center') #定位“筛选 ”按钮

41. print '定位成功'

42. break

43. except Exception as e:

44. print e

45. driver.find_element_by_css_selector('.filter-select.flex-center').click()

46. time.sleep(5)

47. driver.quit()</code>
