“Test-driven development saves time, increases confidence, and is fun! When done properly, the extra effort involved in writing tests usually saves time later by preventing bugs and reducing the need for debugging.”

“Deploy early and often. The more frequently you deploy, the smaller the changes in each deployment, and hence the fewer things that can go wrong.”
