Overview/Description
Defensive Programming is a methodology for writing code that is not prone to present or future errors potentially caused by unexpected user inputs/actions. In this course you will explore the fundamentals of defensive programming including inspections, testing, input validation, error handling, planning, methods, variables, assertions, and iterative design.

Target Audience
Developers seeking an introductory guide to developing efficient, secure, applications that are defendable against a variety of issues.
