Fix webdriver.chrome.driver system property Error

Background – webdriver.chrome.driver system property

I was following along Selenium’s quick-start guide but kept getting an error, “The path to the driver executable must be set by the webdriver.chrome.driver system property“. Most of the answers I found were for Java and simply set the value in code. I tried a similar fix in C# to no avail. Finally, I found a solution that works that sets the values as command-line parameters when I launch the Node.

Files

All files were placed in C:\Selenium. An entry was added to my Windows PATH variable by:

  1. Right-click “This PC” and select “Properties”
  2. In the left navigation menu, select “Advanced system settings”
  3. Select the “Advanced” tab
  4. Select “Environment Variables…”
  5. Under “System variables” select “Path” and then select “Edit…”
  6. Select “New”
  7. Enter C:\Selenium\
  8. Select “OK”

Start the Hub

The following script will start the Grid Hub (on the default port of 4444).

cd C:\Selenium
java -jar selenium-server-standalone-3.0.0.jar -role hub

Start the Node

The following script will start a Grid Node (on the default port of 5555). It will also register the locations of the Chrome and Firefox WebDrivers (respectively).

cd C:\Selenium
java -Dwebdriver.chrome.driver=C:\Selenium\chromedriver.exe -Dwebdriver.gecko.driver=C:\Selenium\geckodriver.exe -jar selenium-server-standalone-3.0.0.jar -role node -hub http://localhost:4444/grid/register
