Which statement describes best practice for naming and organizing tests?

• A. Tests should be described with generic names
• B. Tests should be descriptive, grouped by functionality, use arrange-act-assert, and be repeatable
• C. Tests should be written in isolation with no repeatability
• D. Tests should avoid any structure to reflect natural coding

Answer: (B)

Clear, descriptive names and a structured organization are essential for test suites. Descriptive test names help you understand exactly what behavior is being verified without opening the test body. Grouping tests by functionality keeps related tests together, making it easier to maintain and update them when a feature changes. Using the arrange-act-assert pattern clarifies the test flow: set up the scenario, perform the action, and verify the outcome, which improves readability and makes failures easier to diagnose. Repeatability is crucial so tests produce the same result every run, ensuring the suite is reliable for automation. The other options miss these benefits: generic names are vague; lack of grouping and structure makes tests hard to navigate and maintain; and aiming for non-repeatable tests undermines trust in the suite.
