What are key points to explain Unit Testing

Question

I want to introduce Unit Testing to some colleagues that have no or little experience with Unit Testing. I\'ll start with a presentation of about an hour to explain the concept

Answer 1

Main points:

• unit tests help both design (by expressing intent) and regression test (by never going away) code;
• unit tests are for lazy programmers who don't want to debug their code again;
• tests have no business of influencing or affecting business logic and functionality, but they do test it fully;
• unit tests demand the same qualities as regular code: theory and strategy, organization, patterns, smells, refactoring;
