Test Driven is the first one-stop shop for Java developers wanting a comprehensive understanding of how to apply test driven development (TDD) methodology to Java. This book takes readers from basic theory to practical techniques to tool support and how-to's for applying TDD with what are often thought of as being "difficult" technology. It's also among the first to cover acceptance test driven development (ATDD). Readers can use the book for getting started with TDD and ATDD, and afterwards for help in solving technical problems such as, "how can I test drive code that uses technology X?" Test Driven takes readers new to TDD and Acceptance TDD and helps them become seasoned test driven developers ready to tackle any Java or J2EE project. Readers will learn the simple rules and underlying dynamics that make TDD such a powerful technique. Along the way the author expertly breaks down those myths that say some J2EE technologies cannot be done test-first, showing how to test drive J2EE components just like regular Java code. He also gives comprehensive coverage to the latest EJB specification, web components from plain Java Servlets to the coolest open source web framework on the block, and data access solutions from raw JDBC to fancy object-relational mapping frameworks. In addition to the usual J2EE technologies, multithreaded programs and Java Swing get a full treatment, too. Readers will also learn how a technique called acceptance test driven development applies the ideas of TDD to the overall software development process, implementing features test-first.
