This error message...

org.openqa.selenium.firefox.NotConnectedException: Unable to connect to host 127.0.0.1 on port 7055 after 45000 ms. Firefox console output:
 Potential driver version mismatch ignored due to missing DLLs igd10umd64 v= and igd10iumd64 v=
*** Blocklist::_preloadBlocklistFile: blocklist is disabled

...implies that the GeckoDriver was unable to initiate/spawn a new Web Client session/instance successfully.

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

  • Your Selenium Client version is 2.45 which is almost 2.5 years older.
  • Your GeckoDriver version is v20.1.
  • Release Notes of 0.19.0 (2017-09-16) clearly mentions the following :

Note that with geckodriver 0.19.0 the following versions are recommended:

  • Firefox 55.0 (and greater)
  • Selenium 3.5 (and greater)
  • Release Notes of 0.16.0 (2017-04-21) clearly mentions the following :

Note that geckodriver v0.16.0 is only compatible with Selenium 3.4 and greater.

  • Your Firefox version is v60.0.

So there is a clear mismatch between Selenium Client v2.45, GeckoDriver v20.1 and Firefox v60.0.

Solution

  • Upgrade JDK to recent levels JDK 8u162.
  • Upgrade Selenium to current levels Version 3.11.0.
  • Upgrade GeckoDriver to GeckoDriver v0.20.1 level.
  • GeckoDriver is present in the specified location.
  • GeckoDriver is having executable permission for non-root users.
  • Upgrade Firefox version to Firefox v60.0 levels.
  • Clean your Project Workspace through your IDE and Rebuild your project with required dependencies only.
  • Use CCleaner tool to wipe off all the OS chores before and after the execution of your Test Suite.
  • If your base Web Client version is too old, then uninstall it through Revo Uninstaller and install a recent GA and released version of Web Client.
  • Take a System Reboot.
  • Execute your Test as a non-root user.
  • Always invoke driver.quit() within tearDown(){} method to close & destroy the WebDriver and Web Client instances gracefully.
