Apache Jakarta JMeter may be used to test performance both on static and dynamic resources (files, Servlets, Perl scripts, Java Objects, Data Bases and Queries, FTP Servers and more). It can be used to simulate a heavy load on a server, network or object to test its strength or to analyze overall performance under different load types. You can use it to make a graphical analysis of performance or to test your server/script/object behavior under heavy concurrent load.

Gump provides large scale continuous integration for various open source projects.

Clover is a code coverage analysis tool. It discovers sections of code that are not being adequately exercised by your unit tests. Clover reports its findings in multiple formats for easy use by the whole team at the project level down to each line of source code.

- Fully integrated with NetBeans, Eclipse, IntelliJ IDEA, JDeveloper 10g, and JBuilder

- Seamless Integration with projects using Ant. Easy integration into legacy build systems with command line interface.

- Accurate, configurable, detailed coverage reporting of Method, Statement, and Branch coverage

- Rich reporting in HTML, PDF, XML or a Swing GUI

- Precise control over the coverage gathering

- Historical charting of code coverage and other metrics

OpenSTA is a distributed software testing architecture designed around CORBA, it was originally developed to be commercial software by CYRANO. The current toolset has the capability of performing scripted HTTP and HTTPS heavy load tests with performance measurements from Win32 platforms.

The Grinder is a JavaTM load-testing framework. It is freely available under a BSD-style open-source license.

The Grinder makes it easy to orchestrate the activities of a test script in many processes across many machines, using a graphical console application. Test scripts make use of client code embodied in Java plug-ins. Most users of The Grinder do not write plug-ins themselves, instead they use one of the supplied plug-ins. The Grinder comes with a mature plug-in for testing HTTP services, as well as a tool which allows HTTP scripts to be automatically recorded.

The next major version of The Grinder, The Grinder 3 is currently available as a beta quality release. The Grinder 3 uses the powerful scripting language Jython, and allows any Java code to be tested without the need to write a plug-in. New users are advised to start with The Grinder 3.

The Grinder was originally developed for the book Professional Java 2 Enterprise Edition with BEA WebLogic Server by Paco Gómez and Peter Zadrozny. Philip Aston took ownership of the code and reworked it to create The Grinder 2. Philip continues to enhance and maintain The Grinder, and welcomes all contributions. Peter, Philip and Ted Osborne published the book J2EE Performance Testing which makes extensive use of The Grinder.
