Everyday Rails Testing with RSpec

A practical approach to test-driven development

About the Book

Built a couple of Rails applications, but struggling with reliable test coverage? Does your application testing consist of clicking around in the browser, hoping you catch everything before your customers do?

It's a common experience for new Ruby on Rails developers! Testing and test-driven development are crucial, but many tutorials don't delve deeply into these components. In Everyday Rails Testing with RSpec, you'll learn tried-and-true techniques for writing clear, effective, maintainable tests in RSpec—in turn, building more trustworthy features for your customers, and saving countless hours refreshing your browser.
