Writing perfect software may be a daunting task for developers, but a few defensive programming techniques which are routinely applied can go a long way toward narrowing the gap between code and ideal. Defensive programming practices are often used where high availability of the application is required, safety if utmost concern, or security is needed for application to work.

Nothing will give you more peace of mind than thoroughly tested code. If it’s been a hassle for you in the past, use an automated framework, such as the one we’ve presented here, to integrate routine testing into your daily work. You (and your users!) will be glad you did.
