Having difficulty accessing the VR Path Registry

  • Software Version: geckodriver-v0.20.0-win64
  • Operating System: Windows 10 Home Single
  • Web Browser: Firefox: 59.0.2 (64-bits)
  • Selenium Software: selenium-java-3.11.0
  • IDE: intelliJ Idea : 2018.1 Community Edition

Greetings! I have recently started using WebDriver with Java in the intelliJ IDEA environment. After importing Selenium with Maven and adding the necessary dependency as instructed on the Selenium Webpage, I downloaded geckodriver and updated the Windows path accordingly. However, when writing my code, I encountered an output that appears to be an error. Could someone provide assistance in helping me understand what is happening?

import org.openqa.selenium.WebDriver;
import org.openqa.selenium.firefox.FirefoxDriver;
public class firstTry {
   public static void main (String [] args){
       WebDriver driver = new FirefoxDriver();
       driver.quit();
   }
}

Although Firefox opens and closes without any issues, I am seeing an output in the console that seems like an error to me. The output includes information such as:

(Output displayed in the text above)
...

How can I resolve this issue? Any suggestions or guidance would be greatly appreciated.

Answer №1

When utilizing GeckoDriver v0.20.0 with Firefox Quantum v59.0.2 (64-bits), your code block appears to be functioning properly and the log stack trace looks satisfactory, except for the absence of the log message :

Promise rejected while context is inactive: Message manager disconnected

According to a discussion on Mozilla Support Forum, this error seems to be related to Privacy Badger. In short, this issue is likely caused by an extension that is not loading or working correctly.

Solution

  • Upgrade your JDK to recent versions JDK 8u162.
  • Update Selenium to the latest version Version 3.11.0.
  • Clean your Project Workspace in your IDE and then Rebuild your project with only necessary dependencies.
  • Utilize CCleaner tool to remove unnecessary tasks from your operating system before and after executing your Test Suite.
  • If your current Firefox version is outdated, uninstall it using Revo Uninstaller and install a newer version of Firefox.
  • Perform a System Reboot.
  • Run your @Test again.

tl;dr

Are unresolved promises rejected prior to a window.unload event?

Update

In my Answer, I mentioned that your stack trace appeared to be sufficient based on current implementations. However, personally, I have not encountered this specific trace on my localhost :

Promise rejected while context is inactive: Message manager disconnected

Some traces may vary depending on the underlying OS. After reviewing the entire discussion on Are unresolved promises rejected prior to a window.unload event?, the essence is:

The issue of promises in unloading pages not being well-specified and implemented consistently is real. The specification for Promise is part of ES6, which doesn't account for Realms needing to disappear in some cases, leading to uncertainty in certain scenarios.

Hence, the conclusion remains: You are good to proceed
