Difference between WebDriver and Selenium in Selenium Grid Node Configuration

Question

I'm using Selenium Grid and noticed that I can configure the seleniumProtocol parameter for the different capabilities in the Node. I can chose between WebDriver and Selenium.

Excerpt from my node.json

{
  "capabilities":
  [
    {
      "browserName": "chrome",
      "platform": "WINDOWS",
      "maxInstances": 5,
      "seleniumProtocol": "WebDriver"
    },
    {
      "browserName": "firefox",
      "platform": "WINDOWS",
      "maxInstances": 205
      "seleniumProtocol": "Selenium",
      "firefox_binary"=".\\firefox-22\\firefox.exe"
    }
  ]
}

What are the differences between those two options?

I couldn't jet find any relevant notes in the internet or the selenium grid wiki.

Thanks in advance

Answer 1

The Selenium Grid and Node is downward compatible. It works with Selenium 1 and Selenium 2 / WebDriver.

The seleniumProtocol parameters define for what version of Selenium the configuration apply.

• Selenium = Selenium 1
• WebDriver = Selenium 2 / WebDriver
