Software testing is indispensable and is one of the most discussed topics in software development today. Many companies address this issue by assigning a dedicated software testing phase towards the end of their development cycle. However, quality cannot be tested into a buggy application. Early and continuous unit testing has been shown to be crucial for high quality software and low defect rates. Yet, current books on testing ignore the developer's point of view and give little guidance on how to bring the overwhelming amount of testing theory into practice. "Unit Testing in Java" represents a practical introduction to unit testing for software developers. It introduces the basic test-first approach and then discusses a large number of special issues and problem cases. The book instructs developers through each step and motivates them to explore further. It shows how the discovery and avoidance of software errors is a demanding and creative activity in its own right and can build confidence early in a project. It demonstrates how automated tests can detect the unwanted effects of small changes in code within the entire system. This book also discusses how testing works with persistency, concurrency, distribution, and web applications. It includes a discussion of testing with C++ and Smalltalk.
