python+selenium自動化指令碼跑完後提示TextIOWrapper資訊__python

自動化指令碼跑完後，提示：.<_io.TextIOWrapper name='<stderr>' mode='w' encoding='UTF-8'> 

Time Elapsed: 0:00:10.638064

指令碼能運行，並且報告也產生了。

就是有這個提示。

呼叫指令碼：

#-*- coding: utf-8 -*-import HTMLTestRunnerimport unittestfrom test_B.case_001 import Testdef suite():   onetest = unittest.TestSuite()   onetest.addTest(Test("login_test"))   return onetestif __name__ == '__main__':   filename = "D:\\Pycharm\\result\\report0.html"   fp = open(filename,"wb")   runner =HTMLTestRunner.HTMLTestRunner(stream=fp,title=u'Report_title',description=u'Report_description')   runner.run(suite())   fp.close()

用例：

# -*- coding: utf-8 -*-from selenium import webdriverfrom time import sleepimport unittestclass Test(unittest.TestCase):   def setUp(self):      self.driver = webdriver.Firefox()      self.driver.implicitly_wait(5)      self.driver.get('http://10.2.29.216:8080/kmhc-image-report-web/#/login')   def login_test(self):      self.driver.find_element_by_id('name-txt').send_keys('longtest3')      self.driver.find_element_by_id('pass-txt').send_keys('123456')      self.driver.find_element_by_xpath('/html/body/div/div/div[2]/div/div/form/div[2]/div[4]/div').click()   def tearDown(self):      # sleep(2)      sleep(3)      self.driver.close()      pass
