title: How to assert/verify successful login using Python / Selenium Webdriver
body: <p>I have done a little research and could not find any answer specific to Selenium WebDriver with Python. 
  I can successfully sign into the page but I cannot find way(s) to verify that the login was successful. Page title does not work for me since it does not change. 
  Python Selenium documentation does not have any good explanation or examples. 
  All I want to do after this code is to put a line and assert that the username "Tuto" is visible on the page</p>
  
  <pre><code>LoginButtonLocator = "//a[contains(text(), 'Login')]"
  facebookConnectButtonLocator = "//a[contains(text(), 'Connect with Facebook')]"
  
  facebookLoginLocatorID = "email"
  facebookPasswordLocatorID = "pass"
  facebookLoginButtonLocatorID = "loginbutton"
  
  LoginButtonElement = WebDriverWait(driver, 20).until(lambda driver: driver.find_element_by_xpath(LoginButtonLocator))
  LoginButtonElement.click()
  facebookConnectButtonElement = WebDriverWait(driver, 20).until(lambda driver: driver.find_element_by_xpath(facebookConnectButtonLocator))
  facebookConnectButtonElement.click()
  facebookLoginElement = WebDriverWait(driver, 20).until(lambda driver: driver.find_element_by_id(facebookLoginLocatorID))
  facebookLoginElement.send_keys(facebookID)
  facebookPasswordElement = WebDriverWait(driver, 20).until(lambda driver: driver.find_element_by_id(facebookPasswordLocatorID))
  facebookPasswordElement.send_keys(facebookPW)
  facebookLoginButtonElement = WebDriverWait(driver, 20).until(lambda driver: driver.find_element_by_id(facebookLoginButtonLocatorID))
  facebookLoginButtonElement.click()
  </code></pre>
