  import unittest 
  
  class LoginTest(unittest.TestCase):
  
  def test_Login(self):
      self.driver = webdriver.Firefox()
      self.driver.get("https://www.facebook.com/")
      driver = self.driver
      facebookUsername = "xxxxxxxx"
      facebookPassword = "xxxxxxxx"
  
      emailFieldId="email"

      loginButtonXpath="//input[@value='Log in']"
      fbLogoXpath = "(//a[contains(@href,'logo')])[1]"
  
      emailFieldElement = WebDriverWait(driver, 1).until(lambda driver: driver.find_element_by_id(emailFieldId))
      passFieldElement = WebDriverWait(driver, 1).until(lambda driver: driver.find_element_by_id(passFieldId))
      loginButtonElement = WebDriverWait(driver, 1).until(lambda driver: driver.find_element_by_id(loginButtonXpath))
  
      emailFieldElement.clear()
      emailFieldElement.send_keys(facebookUsername)
      passFieldElement.clear()
      passFieldElement.send_keys(facebookPassword)
      loginButtonElement.click()
      WebDriverWait(driver, 1).until(lambda driver:     driver.find_element_by_id(fbLogoXpath))
  def tearDown(self):
