Some programmers believe that those who don't use automated tests are lazy because testing helps catch bugs early, improves code quality, and ensures long-term maintainability. They argue that skipping tests leads to technical debt, makes debugging harder, and slows down future development. However, not all programmers who avoid automated tests are lazy. Some may work under tight deadlines, in environments where testing isn't a priority, or on small projects where manual testing seems sufficient. Others might lack experience with testing frameworks or simply believe that writing tests slows them down. Ultimately, the perception of laziness comes from the idea that automated tests require discipline and foresight—qualities associated with good software engineering practices.
