Can you use multiple instances of Edge on a Selenium Grid Node?

Question

Using the config below, I am only seeing one instance of Edge running on my node.

When using chrome with a similar setup, I can run multiple browsers on the same node.

Here is the config.json I am using:

{
  "capabilities":
      [
        {
          "browserName": "MicrosoftEdge",
          "maxInstances": 4
        }
      ],
  "configuration":
  {
    "proxy": "org.openqa.grid.selenium.proxy.DefaultRemoteProxy",
    "maxSession": 5,
    "port": 7777,
    "register": true,
    "registerCycle": 5000,
    "hubPort": 4444,
    "hubHost": 192.168.56.101
  }
}

I am running the hub and node on a single VM running

• Win10 Aniversery Edition
• the corresponding Edge WebDriver (14393)
• Selenium 2.53.1 selenium-server-standalone.jar.
• Java 8

Answer 1

No.

As per MS ( https://twitter.com/instylevii/status/783480823445987329 ), at this time the MS Edge WebDriver support only one session per Selenium Grid node .

Answer 2

As a workaround, you can exploit Windows virtual desktop basic feature.

See headless-selenium-for-win

I've used and validated it on a Windows 2012 server with 5 concurrent IE11 instances.
