Discuss ISTQB CTAL-TTA Exam Topic 1 Question 50

Which of the following statements about Application Programming Interface (API) testing is TRUE?

AAPI testing cannot be applied to distributed systems

BCombinatorial testing cannot be applied to API testing

CAPI testing may require the use of specialized tools

DAPIs are loosely coupled, so timing glitches will not happen

Suggested Answer: C

API testing involves testing the application programming interfaces directly and is often a critical part of integration testing. Here are the clarifications for each option:

A . API testing cannot be applied to distributed systems: This is incorrect. API testing is commonly used in distributed systems to ensure that different components interact correctly.

B . Combinatorial testing cannot be applied to API testing: This is incorrect. Combinatorial testing techniques can be very effective in API testing to cover various parameter combinations.

C . API testing may require the use of specialized tools: This is true. API testing often involves tools like Postman, SoapUI, and others to facilitate sending requests and validating responses, which may not be feasible manually.

D . APIs are loosely coupled, so timing glitches will not happen: This is incorrect. Even though APIs are designed to be loosely coupled, timing issues can still occur, especially in asynchronous operations and in systems where timing is critical.

Therefore, the correct answer is C. API testing may require the use of specialized tools.

Agreed, C makes sense. Manual testing is tough.

Reiko 7 days ago

I think C is true. Specialized tools are often needed.

Lezlie 12 days ago

B is incorrect too. Combinatorial testing can be useful in APIs.

Lynelle 17 days ago

C makes the most sense. Tools help streamline the process.

Laquanda 23 days ago

D is misleading. Timing issues can still occur.

Ty 28 days ago

A is definitely false. APIs work in distributed systems.

Martha 1 month ago

Agreed! API testing is complex without the right tools.

Nguyet 1 month ago

I think C is true. Specialized tools are often needed.

Jerry 1 month ago

C is spot on, can't imagine doing API testing without the right tools.

Queenie 2 months ago

Combinatorial testing can actually be useful for API testing, so B is false.

Alyssa 2 months ago

Surprised to see D; timing glitches can happen even with loosely coupled APIs!

Wendell 2 months ago

I disagree, A is not correct. API testing can work with distributed systems.

Narcisa 2 months ago

C is definitely true, specialized tools are often needed.

Darrin 2 months ago

I thought APIs were always loosely coupled, but timing issues can still occur?

Salena 2 months ago

Combinatorial testing can be applied, so B is false.

Kanisha 3 months ago

Wait, D seems off. Timing glitches can happen with APIs.

Lonna 3 months ago

I disagree, A is misleading. API testing can work in distributed systems.

Rodrigo 3 months ago

C is definitely true, specialized tools are often needed.

Remedios 3 months ago

D sounds off to me; I feel like timing issues can still occur with loosely coupled APIs, but I need to double-check that.

Dorian 3 months ago

I vaguely remember something about combinatorial testing being relevant to APIs, so I think B might be incorrect.

Noah 4 months ago

I'm not so sure about A; I feel like API testing can be applied to distributed systems, but I can't recall the details.

Theron 5 months ago

I think I remember that API testing can definitely require specialized tools, so maybe C is the right answer?
