Which term describes the process of verifying that a program runs as intended?

• A. Validation checks
• B. Testing
• C. Inputs
• D. Range check

Answer: (B)

Testing is the process of verifying that a program runs as intended. By running the program with a variety of inputs and scenarios and comparing the observed results to what should happen, you check that the software behaves correctly and reliably. This can be done manually or with automated tests, and it covers different levels such as unit tests for individual components, integration tests for how parts work together, and system tests for the overall behavior. Validation checks focus on data entering the program—ensuring inputs meet criteria like format or non-emptiness—rather than proving the program itself works correctly. A range check is a specific type of validation to ensure a value falls within allowed limits, which is about input validity, not about validating overall program execution. Inputs are simply the data fed into the program, not the act of testing how the program runs. So, the term that best describes verifying that the program runs as intended is testing.
