“my_test”对象没有属性“find_element_by_xpath”

Question

1.这是test_loginqq.py的代码：

 #coding=utf-8
 from selenium import webdriver
 import time
 class loginout():

def test_login(self,driver):


    driver = webdriver.Firefox()
    driver.get("https://en.mail.qq.com/cgi-bin/loginpage")
    driver.implicitly_wait(30)
    driver.switch_to_frame("login_frame")
    driver.find_element_by_id("switcher_plogin").click()
    driver.find_element_by_id("u").clear()
    driver.find_element_by_id("u").send_keys("*****")
    #driver.find_element_by_id("emailTips_0").click()
    driver.find_element_by_id("p").clear()
    driver.find_element_by_id("p").send_keys("****")
    driver.find_element_by_id("login_button").click()
    title=driver.title
    print (title)
    driver.implicitly_wait(30)
    user=driver.find_element_by_id("useraddr").text
    print user
    print "log in successfully"
    #driver.quit()
def test_logout(self,driver):
    #driver.implicitly_wait(30)
    driver.find_element_by_xpath("//a[test()='Sign out']").click()
    title=driver.title
    print title
    driver.quit()

2.这是test_main.py的代码：

  #coding=utf-8
  from selenium import webdriver
  from test_loginqq import loginout
  import time
  import unittest
      class my_test(unittest.TestCase):
                  def setUp(self):
                      print "test start"
                  def test_test(self):

                      loginout().test_login(self)
                      loginout().test_logout(self)

                  def test_test0(self):
                      a="hello"
                      b="hello world"
                      self.assertIn(a,b,msg='a is not in b')
                 def tearDown(self):
                     print "test end"
 if __name__=='__main__':
      suite=unittest.TestLoader().loadTestsFromTestCase(my_test)
      unittest.TextTestRunner(verbosity=2).run(suite)

3.当我运行 test_main.py 时，我得到一个错误：'my_test' object has no attribute 'find_element_by_xpath'，我对此一无所知，有人可以帮我解决我的问题吗？

Answer 1

你应该在 loginout 类中实例化 webdriver.Firefox()

这段代码也许你想要：

     #coding=utf-8
 from selenium import webdriver
 import time
 class loginout():
   def test_login(self, driver):

    driver.get("https://en.mail.qq.com/cgi-bin/loginpage")
    driver.implicitly_wait(30)
    driver.switch_to_frame("login_frame")
    driver.find_element_by_id("switcher_plogin").click()
    driver.find_element_by_id("u").clear()
    driver.find_element_by_id("u").send_keys("*****")
    #driver.find_element_by_id("emailTips_0").click()
    driver.find_element_by_id("p").clear()
    driver.find_element_by_id("p").send_keys("****")
    driver.find_element_by_id("login_button").click()
    title=driver.title
    print (title)
    driver.implicitly_wait(30)
    user=driver.find_element_by_id("useraddr").text
    print user
    print "log in successfully"
    #driver.quit()
def test_logout(self,driver):
    #driver.implicitly_wait(30)
    driver.find_element_by_xpath("//a[test()='Sign out']").click()
    title=driver.title
    print title
    driver.quit()

 #coding=utf-8
  from selenium import webdriver
  from test_loginqq import loginout
  import time
  import unittest
      class my_test(unittest.TestCase):
                  def setUp(self):
                      print "test start"
                  def test_test(self):
                      driver = webdriver.Firefox()
                      loginout().test_login(driver)
                      loginout().test_logout(driver)

                  def test_test0(self):
                      a="hello"
                      b="hello world"
                      self.assertIn(a,b,msg='a is not in b')
                 def tearDown(self):
                     print "test end"
 if __name__=='__main__':
      suite=unittest.TestLoader().loadTestsFromTestCase(my_test)
      unittest.TextTestRunner(verbosity=2).run(suite)

你的电脑里有geckodriver吗？如果没有，请在此处下载：geckodriver.exe，并将文件 gecko 移动到 C:\Windows\System32。在环境变量中添加geckodriver，让你的电脑正确接受。
