qftestJUI
Record/playback test tool from Quality First Software for creation, execution and management of automated Java/Swing application tests. Includes a natural user interface, scripting capabilities, and a component recognition algorithm that takes into account a variety of attributes. Recorded GUI elements, user actions and associated data are automatically integrated into an editable tree view reflecting the hierarchical structure of the application's GUI. Extensive documentation.

Cactus
A simple open-source test framework for unit testing server-side java code (Servlets, EJBs, Tag Libs, Filters, etc.). Intent is to allow fine-grained continuous testing of all files making up an application: source code but also meta-data files (such as deployment descriptors, etc) through an in-container approach. It uses JUnit and extends it. Typically use within your IDE, or from the command line, using Ant. From Apache Software Foundation.

JUnitPerf
Allows performance testing to be dynamically added to existing JUnit tests. Enables quick composition of a performance test suite, which can then be run automatically and independent of other JUnit tests. Intended for use where there are performance/scalability requirements that need re-checking while refactoring code. By Mike Clark/Clarkware Consulting, licensed under the BSD License.

QStudio for Java
Java code inspection tool from QA Systems allows automation of a major portion of code inspection process, for early detection of software defects and automatic assessment of code quality. Couples advanced static analysis capabilities to ISO 9126 quality standard framework. Integrates with leading Java Development Environments and platforms. Supports customizing existing rules and defining custom rules.

Koalog Code Coverage
Code coverage analyzer for Java applications from Koalog SARL. Includes: in-process or remote coverage computation, capability of working directly on Java method binaries (no recompilation), predefined (XML, HTML, LaTex, CSV, TEXT) or custom report generation, and session merging to allow compilation of overall results for distinct executions. Integrates with Ant and JUnit.

Abbot Java GUI Test Framework
Testing framework by Timothy Wall provides automated event generation and validation of Java GUI components, improving upon the very basic functions provided by the java.awt.Robot class. (Abbot = "A Better 'Bot'). The framework may be invoked directly from Java code or accessed without programming through the use of scripts via 'Costello', a script editor/recorder. Suitable for use both by developers for unit tests and QA for functional testing. Free - available under the GNU Lesser General Public License.

JUnit - Framework to write repeatable java unit tests
A regression testing framework written by Erich Gamma and Kent Beck. For use by developers implementing unit tests in Java. Free Open Source Software released under the IBM Public License and hosted on SourceForge. Site includes a large collection of extensions and documentation.

jfcUnit
Framework for developing automated testing of Java Swing-based applications at the UI layer (as opposed to testing at lower layers, for which JUnit may be sufficient). Provides recording and playback capabilities. Also available as plugins for JBuilder and Eclipse. Free Open Source Software from SourceForge site.

Jemmy
A Java library that is used to create automated tests for Java GUI applications. Contains methods to reproduce all user actions which can be performed on Swing/AWT components (i.e. button pushing, text typing, tree node expanding, ...). JemmyTest is a program written in Java which uses the Jemmy API to test applications; it can be used separately as well as together with the NetBeans IDE.

JBench
Freeware Java benchmarking framework to compare algorithms, virtual machines, etc. for speed. Available as binary distribution (including documentation), source distribution, or jar file.

Clover
Code coverage tool for Java from Cenqua. Fully integrated plugin for NetBeans, JBuilder, and other IDE's. Seamless integration with projects using Apache ANT. View coverage data in XML, HTML, PDF, or via a Swing GUI.

TrueJ
Source code audit and metrics tool from BlueBay systems. Fifty different audits and metrics, compiler-style output, integrates with a variety of editors/IDE's, configurable, integrates with build tools for quality gate and reporting, highly scalable.

JCover
Java code test coverage analysis tool from Codework Limited. Works with source or compiled files. Gathers coverage measures of branches, statements, methods, classes, file, package and produces reports in multiple formats. Coverage difference comparison between runs. Coverage API provided.

reView
Java source code visualization tool from Headway Software. Reverse engineer and automatically lay out and view code, components, and dependencies for Java, C, and C++ applications. Shows all dependencies, at all levels and between all levels; method, class, package, application.
