Test-Driven Development (TDD) is a technique for building software that guides software development by writing tests. Write the functional code until the test passes. Write the functional code until the test passes. Refactor both new and old code to make it well structured.

It all has to be very reactive; you keep fiddling with the code until it gets traction. Under those conditions, it doesn’t make sense to cross all the t’s and dot the i’s as the life expectancy of the code is weeks or months. Some people invented a fun little game called “test driven development” (TDD).
