A team is automating tests for an API that depends on a customer relationship management (CRM) system. The CRM system has a sandbox environment that is refreshed weekly. The team wants to run tests against the sandbox but is concerned about data consistency. What is the best approach?

Create test data in the sandbox at the beginning of each test run.

Use the production CRM system for tests to avoid data refresh issues.

Run tests only immediately after the sandbox refresh.

Mock the CRM system to avoid data consistency issues.

A team is automating tests for an API that depends on a third-party weather service. The weather service is free but has a daily call limit. The team wants to run tests frequently in CI. What is the best strategy to avoid hitting the daily limit?

Use service virtualization to simulate the weather service for most tests, and use the real service for a small set of smoke tests.

Increase the daily limit by paying for a premium plan.

Use the real weather service for all tests to ensure accuracy.

Cache the weather responses in the test environment to avoid repeated calls.

Why can a dependency on a third-party external API make automated tests less stable?

The external API requires more test data than internal APIs

The external API may change its response format without notice

The external API is always faster than internal services

The external API is typically written in a different programming language

An organization is automating tests for a customer-facing API that reads from a shared database also used by production. The team notices that test runs sometimes fail because the database schema changes during test execution. What is the most effective way to address this dependency?

Use the production database but mark test data with a special prefix to avoid conflicts.

Mock the database layer in the API tests so that no real database is used.

Coordinate with the database team to freeze schema changes during the test execution window.

Run the automated tests against a dedicated test database that is restored from a known snapshot before each test run.

A team is automating tests for a payment API that depends on an external fraud-detection service. During test execution, the fraud service occasionally returns 503 errors, causing intermittent test failures. The team wants to stabilize the automated tests without reducing coverage of the payment API's own logic. What should they do?

Retry the test automatically when a 503 is received, without changing the test design.

Use service virtualization to simulate the fraud service's responses, including error scenarios, while running a small set of contract tests against the real service.

Increase the timeout for the fraud service call in the test configuration.

Replace the external fraud service with a stub that returns predefined responses for all test cases.

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.
