testNG/selenium webdriver limited to 5 parallel tests

Question

I am running selenium webDriver with the maven surefire plugin and using testNG and have been able to parallelize my tests reusing one JVM instance. for some reason I am unsure

Answer 1

If you are using a Selenium Grid, then it makes sense that your tests are being limited to 5 at a time. The factory Selenium Grid properties allow a grid to run:

WebDriver: - 5 Google Chrome - 5 Firefox - 1 IE

Legacy (RC): - 5 Google Chrome - 5 Firefox - 1 IE

You can change these values using a node configuration json file.

nodeConfig.json

{
  "capabilities":
      [
        {
          "browserName": "*chrome",
          "maxInstances": 2,
          "seleniumProtocol": "Selenium"
        }
        ... (any other browser capabilities here)
      ],
  "configuration":
  {
    "proxy": "org.openqa.grid.selenium.proxy.DefaultRemoteProxy",
    "maxSession": 10,
    "port": 5555,
    "register": true,
    "registerCycle": 5000,
    "hubPort": 4444
  }
}

Then when running your nodes:

java -jar selenium-server-standalone.jar -role node -nodeConfig nodeConfig.json ...
