Grid setup and configuration in Selenium Python - Interactive Code Practice

Practice - 5 Tasks

1fill in blank

easy

Complete the code to connect to the Selenium Grid hub.

Selenium Python

from selenium import webdriver
from selenium.webdriver.common.desired_capabilities import DesiredCapabilities

hub = webdriver.Remote(command_executor='http://localhost:4444/wd/hub', desired_capabilities=[1])

hub.quit()

Drag options to blanks, or click blank then click option'

BDesiredCapabilities.SAFARI

CDesiredCapabilities.CHROME

DDesiredCapabilities.EDGE

💡 Hint

Common Mistakes

Using a wrong DesiredCapabilities value that does not match the node's browser.

Forgetting to specify desired_capabilities parameter.

The hub needs to know which browser capabilities to use. Here, we use DesiredCapabilities.CHROME to specify Chrome browser.

medium

Complete the code to register a node to the Selenium Grid hub using command line.

Selenium Python

java -jar selenium-server-standalone.jar -role node -hub http://localhost:4444/grid/register -port [1]

Drag options to blanks, or click blank then click option'

💡 Hint

Common Mistakes

Using the same port as the hub (4444) for the node.

Choosing a port that is already in use.

The node must run on a different port than the hub. Port 5555 is commonly used for nodes.

Fix the error in the node configuration JSON to specify the correct browser name.

Selenium Python

{
  "capabilities": [
    {
      "browserName": "[1]",
      "maxInstances": 5
    }
  ],
  "configuration": {
    "port": 5555,
    "hub": "http://localhost:4444/grid/register"
  }
}

Drag options to blanks, or click blank then click option'

💡 Hint

Common Mistakes

Using uppercase or incorrect browser names.

Using browser names that do not match installed browsers on the node.

The browserName must be lowercase and match the browser the node supports. "chrome" is the correct value for Chrome browser.

4fill in blank

hard

Fill both blanks to create a Python test that connects to the Selenium Grid hub and opens a webpage.

Selenium Python

from selenium import webdriver
from selenium.webdriver.common.desired_capabilities import DesiredCapabilities

browser = webdriver.Remote(command_executor='http://localhost:4444/wd/hub', desired_capabilities=[1])
browser.get([2])
browser.quit()

Drag options to blanks, or click blank then click option'

ADesiredCapabilities.FIREFOX

B"https://example.com"

CDesiredCapabilities.CHROME

D"http://localhost"

💡 Hint

Common Mistakes

Mixing browser capabilities and URL values.

Forgetting to put quotes around the URL.

Use DesiredCapabilities.CHROME to specify Chrome browser and open the URL https://example.com.

5fill in blank

hard

Fill all three blanks to create a Python dictionary comprehension that filters nodes by maxInstances and browserName.

Selenium Python

filtered_nodes = {node['id']: node for node in nodes if node['maxInstances'] [1] 3 and node['browserName'] == [2] and node['status'] == [3]

Drag options to blanks, or click blank then click option'

A>

B"chrome"

C"active"

D<

💡 Hint

Common Mistakes

Using wrong comparison operators like < instead of >.

Forgetting quotes around string values.

Mixing up the order of conditions.

The comprehension filters nodes with maxInstances greater than 3, browserName equal to "chrome", and status equal to "active".
