Advanced Defensive Programming Techniques
This course will lead you step by step through the process of developing defensive design practices, which can substitute common defensive coding, for the better of software design and implementation.
Learning Journey Context
Works well as a continuation after mastering Software Development fundamentals. It bridges the gap toward advanced, production-level engineering.
Relevant for professionals pursuing roles within Software Development.
Quick Facts
What You’ll Learn
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.
