In Detail

Automated testing has emerged as an important approach to improving reliability and maintainability. RSpec is one of the most mature and powerful testing tools for the Ruby programming language, and arguably for any language. Its vast array of features combined with its simple, intuitive syntax allow you to create a broad variety of automated tests, specifications, and examples. Not only can tests catch bugs, they can improve the quality of your Ruby code, encouraging modularity, and allowing changes to be made efficiently and with confidence.

In this book practical features are covered with a view to using simple, stable tools to develolÃ?
