{"product_id":"9780134291086","title":"Developer Testing: Building Quality into Software","description":"\u003cp\u003eHow 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 crunches”—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.\u003c\/p\u003e \u003cp\u003e \u003c\/p\u003e \u003cp\u003eIn \u003ci\u003e \u003cb\u003eDeveloper Testing, \u003c\/b\u003e \u003c\/i\u003eleading test expert and mentor Alexander Tarlinder presents concise, focused guidance for making new and legacy code far more testable. Tarlinder helps you answer questions like: \u003ci\u003eWhen have I tested this enough? How many tests do I need to write? What should my tests verify?\u003c\/i\u003e You’ll learn how to design for testability and utilize techniques like refactoring, dependency breaking, unit testing, data-driven testing, and test-driven development to achieve the highest possible confidence in your software. Through practical examples in Java, C#, Groovy, and Ruby, you’ll discover what works—and what doesn’t.\u003c\/p\u003e \u003cp\u003e \u003c\/p\u003e \u003cp\u003eYou can quickly begin using Tarlinder’s technology-agnostic insights with most languages and toolsets while not getting buried in specialist details. The author helps you adapt your current programming style for testability, make a testing mindset “second nature,” improve your code, and enrich your day-to-day experience as a software professional.
