The Ruby and Rails communities have begun to eMB race test-driven design, and for many employers, it’s a skill expected of developers. At thoughtbot, we consider it a core competency and drive all development through tests. For developers new to testing, however, the most common question asked is,

How this course will help you

“Why test?” Josh discusses the goals of testing, forms of
