desired_caps = {}
desired_caps['platformName'] = 'Android'
desired_caps['platformVersion'] = '6.0'
desired_caps['deviceName'] = '03b25e23437f1056'
desired_caps['appPackage'] = '待测试的apk的包名'
desired_caps['appActivity'] = '待测试的apk的需要启动的activity'

driver = webdriver.Remote('http://localhost:4723/wd/hub', desired_caps)
time.sleep(2)

driver.find_element_by_name('文字').click()
time.sleep(5)
driver.find_element_by_name('文字1').click()
element1 = driver.find_element_by_name('文字2').text
if element1:
    if element1 != '文字2':
        print 'fail'
    else:
        print 'pass'

问题分析

  1. 根据错误提示，找到出现问题的地方是比对文字：

    if element1 != '文字2':

    加print输出

     str = '文字2'
 print [element1]
 print [str]

    结果如下所示：

  2. google 错误提示，得到如下答案：

    your error message indicates that you aren’t comparing unicode objects. You are probably comparing a unicode object to a str object 链接地址

解决方案(两种)

  1. 都转换成Unicode进行比较

     if element1:
 if element1 != u'文字2':
     print 'fail'
 else:
     print 'pass'

  2. 在代码开头引入 from __future__ import unicode_literals
