Which of the following is an example of an infrastructure component that an API typically depends on?

The API's source code repository

The test automation framework's reporting tool

The API's OpenAPI specification document

The database used to store application data

A team is automating tests for a reporting API that aggregates data from three internal microservices. The microservices are still under development and their response formats change frequently. The team wants to test the reporting API's logic without being blocked by the microservices' instability. What is the most effective approach?

Use stubs that return fixed responses for the microservices, and update the stubs when the microservices' contracts change.

Wait until the microservices are stable before writing any automated tests.

Use the real microservices but mark the tests as 'flaky' when they fail.

Run the tests only against the production environment where the microservices are stable.

How can a network dependency impact the execution of API test automation?

It determines the programming language used for the tests

It specifies the assertion logic for validating responses

It defines the test data that must be used in the tests

It can cause test failures due to latency or connectivity issues

A team is automating tests for a multi-tenant API that depends on a shared authentication service. The authentication service is critical and has a high availability requirement. The team wants to prioritize test automation efforts. Which dependency should be the primary focus of automated tests?

The internal logging service, because it is used for auditing.

The database, because it stores all tenant data.

The authentication service, because it is a single point of failure for all tenants.

The external payment service, because it handles financial transactions.

What is the purpose of using a mock in API test automation?

To simulate the behavior of a real dependency in a controlled way

To increase the response time of the real API

To log all requests made to the real API

To permanently remove the dependency from the production environment

Objective: Explain Test Automation Dependencies for an API Infrastructure CTAL-TAE Practice Questions (Page 4)

Part of the Domain 5: Implementation and Deployment Strategies for Test Automation domain, which makes up ~12% of our current practice bank. ISTQB does not publish an official question count, but from its 90-minute exam (~35–60 total, ~4–7 in this domain), expect 1–2 from this objective — we provide 22 practice questions to prepare you well beyond it.
