Selenium Grid

Pre-Requisite#

Please make sure that you have installed docker.

Start a docker container with chrome#

Use either Selenium Grid 3 or Selenium Grid 4

Using Selenium Grid 3

1. Setup Hub

$ docker run -d -p 4444:4444 --name selenium-hub selenium/hub

2. Setup Chrome node and register with the hub

$ docker run -d --link selenium-hub:hub selenium/node-chrome

Using Selenium Grid 4

1. Setup Hub

$ docker run -d -p 4444:4444 -p 7900:7900 --shm-size="2g" selenium/standalone-chrome:4.0.0-rc-2-prerelease-20210923

Note: Refer here for more info on docker-selenium setup

Setup Docker in IntelliJ Idea#

Follow the same steps as shown here to set up docker in IntelliJ. Once docker is up and running, open http://localhost:4444/grid/console and check if Selenium Grid 3 with chrome image is up.

Or open http://localhost:4444/ and check if Selenium Grid 4 is up.

Optional Step: If you are using Selenium Grid 4, Open http://localhost:7900/ to inspect container activity with the browser.

Now connect to noVNC client. Click on connect button and enter the password as secret. You can see the Selenium Grid logo as shown in the below screenshot

Let us execute tests against Selenium Grid containers#

Let’s follow the same steps as we did for Selenoid

1. Create a webfeed specific to Selenium Grid
2. Create a cloud-config file specific to Selenium Grid
3. Create a config to use step 1 and 2

Create a webfeed specific to Selenium Grid#

Let us create a webfeed file

src/test/resources/cloud_config/seleniumGrid/seleniumGrid-webfeed.json

content as below:

{
  "desiredCapabilities": {
    "pageLoadStrategy": "eager",
    "enableVNC": true
  },
  "arguments": [
  ],
  "preferences": {
    "managed_default_content_settings.cookies": 2
  },
  "extensions": [
  ],
  "experimentalOptions": {
  }
}

Create a cloud-config file specific to Selenium Grid (Hub)#

Selenium Grid 3

content as below:

{
  "url": "http://localhost:4444/wd/hub"
}

Selenium Grid 4

content as below:

{
  "url": "http://localhost:4444"
}

Create a config to the files we created#

Let us create seleniumGrid.local.properties under config.properties

Lets execute our tests !!

./gradlew clean runWebTests -Dconfig=seleniumGrid.local

Selenium Grid 3 Execution

Selenium Grid 4 Execution
