Network interception (CDP) in Selenium Java - Interactive Code Practice

Practice - 5 Tasks

1fill in blank

easy

Complete the code to create a CDP session for network interception.

Selenium Java

DevTools devTools = driver.[1]();

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

AgetDevTools

BopenDevTools

CstartDevTools

DcreateDevTools

💡 Hint

Common Mistakes

Using a method that does not exist like createDevTools or startDevTools.

The getDevTools() method is used to get the DevTools instance from the WebDriver.

2fill in blank

medium

Complete the code to enable the Network domain in CDP.

Selenium Java

devTools.send(Network.[1]());

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

Aenable

Bdisable

Cstart

Dactivate

💡 Hint

Common Mistakes

Using disable or start which are not valid commands for Network domain.

The enable() command activates the Network domain to start intercepting network events.

3fill in blank

hard

Fix the error in the code to add a listener for network requests.

Selenium Java

devTools.addListener(Network.[1], request -> {
    System.out.println("Request URL: " + request.getRequest().getUrl());
});

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

ArequestSent

BonRequest

CrequestWillBeSent

DnetworkRequest

💡 Hint

Common Mistakes

Using incorrect event names that do not exist in the Network domain.

The correct event name is requestWillBeSent which fires before a network request is sent.

4fill in blank

hard

Fill both blanks to create a map of headers to modify a network request.

Selenium Java

Map<String, Object> headers = new HashMap<>();
headers.put("[1]", "application/json");
headers.put("[2]", "no-cache");

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

AContent-Type

BCache-Control

CAccept

DAuthorization

Attempts:

💡 Hint

Common Mistakes

Confusing header names or using headers unrelated to content type or caching.

The Content-Type header specifies the data format, and Cache-Control controls caching behavior.

5fill in blank

hard

Fill in the blanks to modify and continue a network request with new headers.

Selenium Java

devTools.addListener(Network.requestIntercepted(), request -> {
    Map<String, Object> headers = new HashMap<>(request.getRequest().getHeaders());
    headers.put("[1]", "Bearer token123");
    devTools.send(Network.[2](request.getInterceptionId(), headers));
});

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

AAuthorization

BcontinueInterceptedRequest

CcontinueRequest

DsetRequestHeaders

Attempts:

3 left

💡 Hint

Common Mistakes

Using incorrect header names or wrong Network commands to continue the request.

The Authorization header adds the token. The continueInterceptedRequest command continues the request with modified headers.
