我按照官方的例子修改了一下代码，然后就一直运行出错：
代码：

import unittest
from selenium import webdriver

########################################################################
class FindElementTest(unittest.TestCase):
    """打开 apk 找到"""
    #----------------------------------------------------------------------
    def setUp(self):
        """"""
        desired_capabilities={'aut':'com.example.bebb:1.9.1'}
        self.driver=webdriver.Remote(
            desired_capabilities=desired_capabilities
        )

        self.driver.implicitly_wait(30)
        #全局定义超时，处理find_element_by 等操作超时均为30s
    #----------------------------------------------------------------------
    def test_find_element_by_id(self):
        """"""
        self.driver.get('and-activity://com.example.bebb.PlashScreen')
        #print '11'
        self.assertTrue("and-activity://PlashScreen" in self.driver.current_url)
        print self.driver.current_url

        closeWebView=self.driver.find_element_by_class_name('android.widget.ImageView')
        closeWebView.click
        self.driver.tap([(200,50)],1)


    #----------------------------------------------------------------------
    def tearDown(self):
        """tearDown"""
        self.driver.quit()

if __name__=="__main__":
    unittest.main()

报错：

Ran 1 test in 4.537s

FAILED (errors=1)

我看的是说这部分不对：

self.driver=webdriver.Remote(
            desired_capabilities=desired_capabilities
        )

但是就是不知道为什么不对，我用原代码就可以通过，原代码里边测试的 apk 就是 selendroid-test-app-0.12.0.apk。
