A discussion question exploring whether Data Transfer Objects (DTOs) require unit tests. The author proposes a middle-ground approach: plain DTOs without logic don't need tests, but DTOs with validation, transformation, or non-trivial mapping should be tested as they contain behavior. The post seeks community input on testing strategies, asking whether teams always test DTOs, never test them, only test those with validation/mapping, or rely solely on integration tests.

Do DTOs really need unit tests?
