org.openqa.selenium.WebDriverException: The path to the driver executable must be set by the webdriver.gecko.driver system property;

Question

I am trying to run automation tests using selenium grid. I have configured hub and node as java -jar :D\\selenium-server-standalone-3.4.0.jar -role hub.

 java -Dwebdriver.gecko.driver="D:\geckodriver.exe" -jar D:\selenium-server-standalone-3.4.0.jar -role node  -hub http://localhost:4444/grid/register -port 5566 -browser browserName=Firefox,maxInstances=5           

since my gecko driver and selenium jar is in "D" drive.

But when I am trying to run test from eclipse IDE, it throws an error

org.openqa.selenium.WebDriverException: The path to the driver executable must be set by the webdriver.gecko.driver system property; for more information, see https://github.com/mozilla/geckodriver. The latest version can be downloaded from https://github.com/mozilla/geckodriver/releases
Command duration or timeout: 96 milliseconds  I am unable to identify  where It is going wrong??

I am using firefox 47

Answer 1

I got to know how to solve this issue. Actually it is the issue with Firefox Browser version.

Selenium 3.4.0 works best with geckodriver 0.16 Firefox 52.0.3 and onward.

And I then configured node as

java -Dwebdriver.gecko.driver="D:\geckodriver.exe" -jar D:\selenium-server-standalone-3.4.0.jar -role node  -hub http://localhost:4444/grid/register -port 5566 -browser "browserName=Firefox,version=53.0,maxInstances=5"    

Now it is working.
