What is the primary purpose of validation testing in API?

• A. To confirm the user interface design
• B. To check if the core functionality meets requirements
• C. To test for performance under heavy load
• D. To capture security vulnerabilities

Answer: (B)

The primary purpose of validation testing in API is to ensure that the core functionality meets the specified requirements. This type of testing focuses on verifying that the API behaves as expected and adheres to the specifications outlined in the requirements. During validation testing, various scenarios are executed to evaluate if the API provides the correct responses to different inputs, ensuring that it delivers the intended value to end users. Validation testing serves as a crucial step in the software development life cycle by confirming that the API not only integrates well with other components but also meets business needs and user expectations. The process helps to identify any discrepancies between what the API is supposed to do and how it operates in practice. Other options may cover important aspects of software testing, but they don't align with the specific goal of validation testing. For example, confirming the user interface design is more focused on usability and visual aspects, while testing for performance under heavy load pertains to load testing rather than functional validation. Capturing security vulnerabilities is part of security testing, which is a separate focus aimed at ensuring safe operation, not necessarily validating core functionality against requirements.
