}

Answer 1

This error message...

org.openqa.selenium.WebDriverException: java.net.ConnectException: Failed to connect to localhost/0:0:0:0:0:0:0:1:18218

...implies that the ConnectException was raised while initializing the WebDriver session.

• Ensure GeckoDriver is having executable permission for non-root users.
• Upgrade Firefox version to Firefox v62.0 levels.
• Clean your Project Workspace through your IDE and Rebuild your project with required dependencies only.

• Take a System Reboot .
• Execute your Test as a non-root user.
