Building on techniques used by practitioners of Agile software development, testing continued with Ruby shows you how to get instant feedback about both the quality of your code, and the quality of your tests. We show you how you can create a customized continuous testing environment, especially suited for the projects you're working. We also cover how to extend this environment when working with frameworks like Ruby on Rails, and discuss how to create rapid feedback loop can dramatically increase the rate at which you can deliver working, valuable software. Automated testing is an increasingly common practice in the software development industry. It also helps you improve your writing new tests, by providing instant feedback about problem areas, and create a feedback loop for the visceral quality of the test that you can really feel while you work. Just as continuous integration and test-driven development has changed the definition of software development in the last ten years, Continuous Testing is poised to become standard practice for team development in the next decade.
