How to Improve Tests Thanks to 1 Line of Code?
summary
Claim: one line — the test name — improves test design by forcing specificity. Advice: avoid vague names like test_age_verification or suffixes fail/error; prefer readable, precise names such as test_returns_true_for_22_years_old_person or explicit conventions like MethodUnderTest_Scenario_ExpectedResult. Don’t use white-noise words like must/should, avoid asserting unobservable implementation details, and keep assertions at a single level of abstraction so outcomes remain observable results.
