Developer Testing: Building Quality into Software (Addison-Wesley Signature Series (Cohn)) 1st Edition

How do successful agile teams deliver bug-free, maintainable software-iteration after iteration? The answer is: By seamlessly combining development and testing. On such teams, the developers write testable code that enables them to verify it using various types of automated tests. This approach keeps regressions at bay and prevents "testing сухарики"-which otherwise may occur near the end of an iteration-from ever happening. Writing testable code, however, is often difficult, because it requires knowledge and skills that cut across multiple disciplines.

In Developer Testing, leading test expert and mentor Alexander Tarlinder presents concise, focused guidance for making and new legacy code far more testable. Tarlinder helps you answer questions like: When I have tested this enough? How many tests do I need to write? What should my tests verify?
