Course Description
How often do you have to defend from nulls, zeros, surprising cases hitting switch instruction, impossible else branches, and so on? Is your life a struggle with issues caused by unexpected data or invalid system state? In this course, Advanced Defensive Programming Techniques, you'll learn how to defend by means of design, so that almost all explicit defensive code can be happily removed. First, you'll discover how to build validation. Next, you'll explore how exactly to design a public interface. Finally, you'll cover how to unify error flows, so nothing unpredictable can take you by surprise. By the end of this course, you'll have the necessary knowledge to efficiently develop your own defensive design practice.
