The document discusses test driven development (TDD) and how it can benefit software projects. TDD involves writing tests before code and helps improve code quality through better unit testing, coverage, and design. While it requires discipline, TDD can be applied to both new and legacy code projects. The key principles are to take small iterative steps by writing just enough code to pass each test.
