Error exception is displayed when Selenium WebDriver Firefox executing in Java in Eclipse?

Question

I am getting an error when executing my Selenium WebDriver Java Test Case.

When I run the test case, Eclipse opens the Firefox browser but no URL is entered and no action is happening.

org.openqa.selenium.firefox.NotConnectedException: Unable to connect to host 127.0.0.1 on port 7055 after 45000 ms. Firefox console output:

Answer 1

You have to match your selenium version to a compatible firefox browser version.

Selenium 3.0.x switched to using the new geckodriver. The geckodriver home page has this to say, "Marionette and geckodriver are not yet feature complete. This means it does not yet offer full conformance with the WebDriver standard or complete compatibility with Selenium."

The Selenium java history page has this to say about v3.0.0 and firefox:

"* Firefox is only fully supported at version 47.0.1 or earlier. Support for later versions of firefox is provided by geckodriver, which is based on the evolving W3C WebDriver spec, and uses the wire protocol in that spec, which is liable to change without notice. * You may wish to choose an ESR release such as 45.4.0esr or earlier. * Firefox 47.0.0 is not supported at all."

My advice is to drop back to Selenium v2.53 and firefox v47.

Yes, After tons of troubleshooting, I finally got it to work. For Selenium WebDriver 3.0, u need FF 50.2 , and top of that u will need the gecko driver and put the statement in ur eclipse pointing to the driver. Thanks for posting.

System.setProperty("webdriver.gecko.driver","C:\\Path_To_Your_File\\geckodriver-v0.11.1-win64\\geckodriver.exe");
