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

To keep it really short: Unit testing is about two things

• a tool for verifying intentions
• a necessary safety net for refactoring

Obviously, it is a lot more than that, but to me that pretty much the sums it up.
