New projects
The Test Driven Eclipse (TDE) project
A specific project to integrate unit-testing more fully into development under the Eclipse platform has been started at SourceForge. David Corbin summarizes the idea behind it: "TDE is a project dedicated to making Eclipse the ideal environment for test infected developers. Right now, all that exists is a few ideas swirling in my head, a SourceForge project with one mailing list. Not one byte of code has been written yet to support this. This is a call for other participants (developers, idea people, writers, webmaster, etc.) to explore what this project should be, and build it."

Books
JUnit in action
A guide to unit testing Java applications (including J2EE applications) using the JUnit framework and its extensions, this book provides techniques for solving real-world problems such as unit testing legacy applications, writing real tests for real objects, automating tests, testing in isolation, and unit testing J2EE and database applications.

Tools highlight: Jov and Jusc
Unit testing, a common step in software development, presents a challenge. When produced manually, unit test suites are often insufficient to identify defects. The main alternative is to use one of a variety of automatic unit test generation tools: these are able to produce and execute a large number of test inputs that extensively exercise the unit under test. However, without a priori specifications, developers need to manually verify the outputs of these test executions, which is generally impractical. To reduce this cost, unit test selection techniques may be used to help select a subset of automatically generated test inputs.
Jov (Java Unit Test Selection Tool Based on Operational Violations) and Jusc (Java Unit Test Selection Tool Based on Residual Structural Coverage) are extensions to jUnit aiming to achieve just that.

Read Tao Xie's presentation paper on Tool-Assisted Unit Test Selection Based on Operational Violations for the theory behind the tools.
