1fill in blank

easy

Complete the code to start capturing network logs in Selenium with Python.

Selenium Python

from selenium import webdriver
from selenium.webdriver.chrome.service import Service
from selenium.webdriver.chrome.options import Options

options = Options()
options.set_capability('goog:loggingPrefs', {'performance': '[1]'})

service = Service('/path/to/chromedriver')
driver = webdriver.Chrome(service=service, options=options)

💡 Hint

Common Mistakes

Using 'ERROR' or 'OFF' disables capturing network logs.

Forgetting to set the 'goog:loggingPrefs' capability.

Setting 'performance' logging preference to 'ALL' enables capturing all network logs.

Complete the code to retrieve network logs from the Selenium driver.

Selenium Python

logs = driver.get_log('[1]')
for entry in logs:
    print(entry)

💡 Hint

Common Mistakes

Using 'browser' or 'driver' which do not contain network logs.

Misspelling the log type string.

Network logs are stored under the 'performance' log type in Selenium.

Fix the error in the code to correctly parse network log entries as JSON.

Selenium Python

import json

logs = driver.get_log('performance')
for entry in logs:
    message = json.loads(entry['[1]'])
    print(message)

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

💡 Hint

Common Mistakes

Using incorrect keys like 'messageText' or 'messageData' which do not exist.

Trying to parse the entire entry instead of the 'message' field.

The network log JSON string is stored in the 'message' key of each log entry.

4fill in blank

hard

Fill both blanks to filter network requests for URLs containing 'api' and HTTP method 'GET'.

Selenium Python

filtered_requests = [msg for msg in logs if msg['message']['method'] == 'Network.requestWillBeSent' and msg['message']['params']['request']['[1]'].lower().find('api') != -1 and msg['message']['params']['request']['[2]'] == 'GET']

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

Bmethod

Cheaders

DpostData

💡 Hint

Common Mistakes

Using 'headers' or 'postData' which do not contain URL or method.

Confusing the keys and filtering incorrectly.

The 'url' key contains the request URL, and 'method' contains the HTTP method.

5fill in blank

hard

Fill all three blanks to extract the status code, URL, and response headers from network responses.

Selenium Python

for msg in logs:
    data = msg['message']['params']
    if 'response' in data:
        status = data['response']['[1]']
        url = data['response']['[2]']
        headers = data['response']['[3]']
        print(f'Status: {status}, URL: {url}, Headers: {headers}')

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

Astatus

Burl

Cheaders

DstatusText

Attempts:

💡 Hint

Common Mistakes

Using 'statusText' instead of 'status' for the status code.

Mixing up keys or missing the 'response' key check.

The response dictionary contains 'status', 'url', and 'headers' keys for these values.
