↓↓ ENGLISH DESCRIPTION ↓↓ "Coding Better World Together" is a set of master lessons from the famous Uncle Bob (Robert Cecil Martin), where he gives us a broad vision of the importance and future of Software in today's society. In this fourth lesson, Uncle Bob introduces us to a software development methodology oriented through testing. This is the Test-Driven Development (TDD), a practice with a long learning curve, but with significant results to generate a more robust, safer, more maintainable code and with greater development efficiency. Among other things, Uncle Bob shows us his point of view about the evolution of software to this day and its bright future. ↓↓ DESCRIPCION EN ESPAÑOL ↓↓ "Coding Better World Together" es un conjunto de lecciones magistrales del famoso tío Bob (Robert Cecil Martin), donde nos brinda una visión amplia de la importancia y el futuro del software en la sociedad actual.
