How To Catch Network Failures While Invoking Get() Method Through Selenium And Python?

I am using Chrome with selenium and the test run well, until suddenly internet/proxy connection is down, then browser.get(url) get me this: If I reload the page 99% it will load f

Solution 1:

As per your question and your code trials as you are trying to access the url passed through the argument link you can adapt a strategy where:

• Your program will make pre-defined number of trials to invoke the desired url, which you can pass through range().
• Once you invoke get(link) your program will invoke WebDriverWait for a predefined interval for the url to contain a pre-defined partialURL from the url.
• You can handle this code within a try{} block with expected_conditions method title_contains() and in case of TimeoutException invoke browser.get(link) again within the catch{} block.

• Your modified code block will be:

  #importsfrom selenium.webdriver.support.ui import WebDriverWait
  from selenium.webdriver.support import expected_conditions as EC
  from selenium.common.exceptions import TimeoutException
  # other code works
  browser.get(link)
  for i inrange(3):
      try:
          WebDriverWait(browser, 10).until(EC.title_contains(partialTitle))
          breakexcept TimeoutException:
          browser.get(link)
  logger.warning('there is no valid connection')
