API GraphQL & SOAP Testing 3

Question 1

What is a SOAP 'fault' element used for?

Accepted Answer

Returning error information in a SOAP response when an operation fails

Answer

The SOAP Fault element is the standard mechanism for returning error details (fault code, message, and detail) in a SOAP response body.

Question 2

What GraphQL concept allows multiple queries to be sent in a single HTTP request?

Accepted Answer

Batching

Answer

GraphQL query batching combines multiple operations into a single HTTP request array, reducing round trips and improving client performance.

Question 3

What is 'query depth limiting' used for in GraphQL security testing?

Accepted Answer

Preventing deeply nested queries that could cause excessive database load or DoS

Answer

Query depth limiting rejects GraphQL queries that exceed a maximum nesting depth, preventing attackers from crafting expensive recursive queries.

Question 4

How does testing a SOAP API differ from testing a REST API?

Accepted Answer

SOAP requires XML WSDL-based requests; REST uses flexible JSON and standard HTTP methods

Answer

SOAP testing requires generating valid XML envelopes conforming to a WSDL contract, while REST testing uses more flexible JSON payloads and varied HTTP methods.

Question 5

What is a GraphQL 'fragment' used for in testing and development?

Accepted Answer

Reusing a set of fields across multiple queries to reduce duplication

Answer

GraphQL fragments define reusable sets of fields that can be included in multiple queries, reducing repetition and keeping test queries DRY.
