About the Book

Los tests automáticos no son nada nuevo en el mundo del software y aunque cada vez más desarrolladores están convencidos de su utilidad, pocos escriben tests en su día a día.

Las excusas son siempre las mismas: no sé hacer tests, no tengo tiempo, es algo que tengo pendiente...

Este libro pretende acabar con todas esas excusas y enseñar a los programadores a mejorar la calidad de su código explicando mediante ejemplos qué tipos de tests existen, qué características tienen y cuándo deben de utilizarse .

Iago Lastra Rodríguez

I love everything about software, technology and of course programming! I am very serious about writing clean code. I'm always trying to learn something new about algorithms, good practices, testing, design patterns or software architecture.
