Which scenario correctly matches the testing approach described as development testing plus independent operational testing?

• A. Acceptance testing
• B. Developmental testing and independent operational testing
• C. Unit testing
• D. Cybersecurity testing

Answer: (B)

The idea being tested is the combination of testing done during development with an independent check in an operational environment. Development testing is the work done by the development team while building the product to catch defects early and verify that the design and implementation behave as intended. Independent operational testing is performed by an external or separate group in a production-like environment to confirm the system can operate under real-world conditions and meet user needs. A scenario that includes both elements—testing while developing and then having an independent team test in an operational setting—best matches this approach. Other options focus on narrower areas (user acceptance, low-level unit checks, or security-specific testing) and don’t reflect the combination of development testing plus independent operational testing.
