What type of testing is performed during product development to iteratively improve the product?

• A. Summative Testing
• B. Formative Testing
• C. Acceptance Testing
• D. Regression Testing

Answer: (B)

Formative testing is testing done during development to gather ongoing feedback and guide iterative improvements. This approach fits product development because it emphasizes learning about user needs, usability, and design effectiveness while changes are still easy to implement, letting the team refine features, interfaces, and requirements as work progresses. It's different from summative testing, which happens at the end to judge overall quality; acceptance testing, which validates the product against user needs before release; and regression testing, which rechecks existing functionality after code changes. By focusing on iterative feedback, formative testing supports continuous refinement toward a better product.
