ISTQB Certified Tester Foundation Level v4.0 — Question 73

In the testing quadrants model, which testing is business-facing and supports the team?

Answer options

• A. Security testing
• B. Component testing
• C. API testing
• D. Exploratory testing

Correct answer: C

Explanation

API testing is designed to validate the functionality, reliability, and performance of APIs, which are crucial for business operations and support team workflows. Security testing focuses on identifying vulnerabilities, component testing verifies individual parts of the system, and exploratory testing is more about simultaneous learning and testing rather than direct business support.
