API requirements are usually comprehensive and well-documented, making testing straightforward.

• True

• False

Answer explanation

API requirements are often brief, incomplete, or informal. Testers typically rely on use cases or behavior-driven development (BDD) to identify test conditions.

Risk-based testing is important for APIs because it helps prioritize testing based on potential impact and likelihood of failure.

• True

• False

Answer explanation

Risk-based testing ensures that limited testing time is focused on high-impact areas, helping mitigate the most critical risks.

Regression testing for APIs requires less attention to environmental configurations compared to GUI testing.

• True

• False

Answer explanation

API regression testing must consider factors such as environment dependencies, versioning, and data availability, which can be more complex than GUI testing.

Which method can testers use to define API use cases when formal requirements are lacking?

• Pair Programming

• Behavior-Driven Development (BDD)

• Unit Testing

• Code Review

Answer explanation

BDD uses a "Given-When-Then" format to define use cases and expected outcomes, making it a useful approach when requirements are unclear.

Which of the following is a key component of determining API test coverage goals?

• UI Layout

• Error Handling

• Screen Resolution

• Internet speed

Answer explanation

Error handling is crucial in API testing because APIs often encounter and respond to different error conditions, such as timeouts or invalid inputs.

Which factor is NOT typically considered when determining an API test approach?

• Industry Context

• Tester's Favorite Tool

• Environment Dependencies

• Schedule Constraints

Answer explanation

The test approach is influenced by industry standards, environments, and project timelines, not personal tool preferences.

What type of testing approach prioritizes high-risk areas under tight deadlines?

• Smoke Testing

• Risk-Based Testing

• Regression Testing

• Unit Testing

Answer explanation

Risk-based testing prioritizes testing efforts based on the likelihood and impact of potential failures, which is especially useful when time is limited.

A key artifact in manual API testing with tools like Postman is a __________, which records test steps and results

Answer explanation

A Postman collection is a set of saved API requests that can be shared, automated, and reused for consistent testing.

When performing API regression testing, capturing the __________ number helps track changes between versions.

Answer explanation

Tracking API version numbers is critical for identifying which changes may have introduced defects.

Risk analysis in API testing helps identify high-risk areas, which are often influenced by factors such as usage metrics, response times, and __________ size.

Answer explanation

Message size (both request and response) can impact performance and is an important factor in risk analysis.
