Selenium API Development & Integration 3

Question 1

In Selenium WebDriver, which interface method can be used to intercept and modify network requests to simulate API failures during testing?

Accepted Answer

DevTools CDP network interception

Answer

Chrome DevTools Protocol (CDP) network interception allows Selenium tests to intercept, block, or modify HTTP requests to simulate API failures.

Question 2

What is 'API mocking' in the context of Selenium test automation?

Accepted Answer

Replacing real API calls with simulated responses during testing

Answer

API mocking replaces actual backend API calls with predefined fake responses, allowing tests to run without depending on live backend services.

Question 3

When a Selenium test needs to verify that clicking a button triggers a specific API call, which tool approach is most effective?

Accepted Answer

Capturing network traffic via browser proxy or CDP

Answer

Capturing network traffic through a proxy like BrowserMob or using Chrome DevTools Protocol allows verification that specific API calls were made.

Question 4

Which Selenium utility helps capture API request/response data by acting as a proxy between the browser and the server?

Accepted Answer

BrowserMob Proxy

Answer

BrowserMob Proxy sits between the browser and server, capturing all HTTP traffic including API requests and responses for assertion.

Question 5

In API integration testing with Selenium, what does 'response deserialization' mean?

Accepted Answer

Converting a JSON/XML response string into a usable Java object

Answer

Deserialization converts the raw JSON or XML string from an API response into a structured Java (or other language) object for easy assertion.
