As per the title, now, firefox opens up, seems to do nothing, then disappears!

  1. I've run this before from a local ubuntu 16.04 VM and all was fine.

(Yes, i have upgraded to the latest of selenium etc. as follows: selenium 3.141.0 splinter 0.10.0 six 1.12.0 urllib3 1.25.3) Now, geckodriver.log shows the following:

  1. I've also tried this on a remote ubuntu-16.04 VM (without a GUI ), console shows the same "connection refused" message but this time, geckodriver.log shows a different issue, as follows: (selenium 3.141.0 six 1.12.0 splinter 0.10.0 urllib3 1.25.3)

    1559563047915   geckodriver     INFO    geckodriver 0.18.0

my test code is : 

from splinter import Browser
browser = Browser()
browser.visit( 'https://www.google.com' )
browser.fill( 'q', 'splinter - python acceptance testing     for web application' )
browser.quit()

I appreciate there are similar questions posted to "connection refused" type issues with selenium... I am hoping to find a solution specific to python what seems to me as either a 'network issue' or a 'display issue'...

  • For 1: Maybe try without the profile and see if that makes a difference. For 2:... no GUI seems like it could be the issue. – pcalkins Jun 04 '19 at 20:12

This error message...

...implies that the GeckoDriver was unable to initiate/spawn a new WebBrowsing Session i.e. Firefox Browser session.

Your main issue is the incompatibility between the version of the binaries you are using as follows:

  • Your GeckoDriver version geckodriver v0.18.0. (as per first line in second set of logs ...geckodriver INFO geckodriver 0.18.0...)
  • Your Selenium Client version is 3.141.0.
  • Your Firefox version is unknown to us.

So there is a clear mismatch between the GeckoDriver v0.18.0 Selenium Client v3.141.0.

Solution

  • Upgrade Selenium to current levels Version 3.141.59.
  • Upgrade GeckoDriver to latest GeckoDriver v0.24.0 level.
  • Ensure GeckoDriver is present in the required location.
  • GeckoDriver is having executable permission for non-root users.
  • Upgrade Firefox to current Firefox v65.0.2 levels.
  • Clean your Project Workspace through your IDE and Rebuild your project with required dependencies only.
  • If your base Web Client version is too old, then uninstall it and install a recent GA and released version of Web Client.
  • Always invoke driver.quit() within tearDown(){} method to close & destroy the WebDriver and Web Client instances gracefully.

Note: Always maintain the following GeckoDriver, Selenium and Firefox Browser compatibility matrix

supported_platforms_geckodriver_24

    This is brilliant ! I followed the steps in the solution. It now works like it used to. Bit of a rude shock when things just stop working when you need it to do its thing. I'll need to keep an eye on these tests. OK for now. @DebanjanB Dhonnobaad ! – rikckie Jun 07 '19 at 13:49
