JUnit 4 and Java SE 5: Better Testing by Design
TS-1580

JUnit is an easy-to-use framework that supports developers writing automated tests. Since its introduction, JUnit has been adopted by hundreds of thousands of Java technology developers worldwide and has become the de facto standard for Java technology testing. However, JUnit's architecture has remained virtually unchanged for the seven years of its existence. The advent of annotations and other new features in Java Platform, Standard Edition (Java SE) 5 presented an opportunity to improve both the way tests are written and JUnit's own architecture.

The theme of JUnit 4 is to make JUnit simpler and more powerful, to encourage more developers to write more tests. At the same time, JUnit 4 preserves the investment programmers have made in their existing tests. This session explains and demonstrates how Java SE 5 technology and JUnit 4 work together to make developer testing more approachable for programmers. Because JUnit has also created a rich ecosystem of auxiliary and complementary tools, the presentation introduces and demonstrates some of the unique and most useful JUnit-based open source tools. Finally, it describes features of the original JUnit architecture that have caused problems over the years and how JUnit4 is structured to avoid those mistakes and still retain its power and flexibility.

If you are an experienced JUnit user, the presentation will provide you with strategies, examples, and tools to maximize your efficiency and effectiveness by taking advantage of Java technology's and JUnit's latest features. And if you are new to JUnit, it will give you the motivation and know-how to get started in the right direction.
