Question 1

Which tool is commonly used to create a full fake REST API using only a JSON file as its data source?

Accepted Answer

JSON Server

Answer

JUnit

Answer

Selenium WebDriver

Answer

Apache JMeter

Question 2

In WireMock, what is a 'stub mapping'?

Accepted Answer

A configuration that defines the request criteria to match and the response WireMock should return

Answer

A mapping between JUnit test method names and their corresponding API endpoints

Answer

A code generation tool that produces API client stubs from a WSDL definition

Answer

A database schema used to persist mock responses across server restarts

Question 3

What does 'request matching' mean in the context of API mock servers?

Accepted Answer

The process by which a mock server evaluates incoming request attributes to determine which configured response to return

Answer

Confirming that HTTP methods used by client and server are syntactically identical

Answer

Validating that all request headers conform to the API's published specification

Answer

Comparing two separate API requests to detect differences in their structure

Question 4

What is 'response templating' in API mocking tools such as WireMock?

Accepted Answer

Dynamically constructing mock responses by injecting values extracted from the incoming request

Answer

Automatically generating JSON schemas for API responses from OpenAPI documentation

Answer

Creating HTML-based templates used to render human-readable API documentation

Answer

Auto-generating assertion code from observed API response payloads during test recording

Question 5

Which Postman feature enables you to simulate an API server and return predefined responses without a real backend?

Accepted Answer

Postman Mock Server

Answer

Postman Interceptor

Answer

Postman Monitor

Answer

Postman Collection Runner

Question 6

What is the purpose of the 'record and replay' feature found in API mocking tools?

Accepted Answer

Capturing real HTTP interactions with an actual API and replaying them as mock responses in subsequent tests

Answer

Recording test execution videos for visual regression documentation

Answer

Recording API latency metrics over time and replaying load test scenarios

Answer

Capturing raw network packets for later analysis in security testing workflows

Question 7

In Mockoon, what is a 'route'?

Accepted Answer

A defined endpoint with request matching rules and a configured response within the mock server

Answer

A network path configuration between the client machine and the mock server host

Answer

A URL redirect rule that forwards certain API requests to an external upstream service

Answer

A sequence of API test steps executed in a specific order within a test collection
