The Apache JMeter is a 100% pure Java desktop application designed for performance and load testing of servers. It was primarily designed for Web/HTTP testing but it has been expanded to include support for a variety of testing modules. It ships with modules for HTTP and SQL databases (using JDBC). It may be used to test server performance both on static and dynamic resources, to simulate a heavy load on a server or network to test its strength, or to analyse overall performance under different load types. It also provides pluggable interfaces for customizing data visualization, test synchronization, and the construction and execution of tests.
CodeWizard uses the magic of Source Code Analysis technology to improve and standardize your Java[tm] code-automatically. CodeWizard automatically enforces Java coding standards so you can produce clean, robust code quickly and easily. This is a commercial product, you need an eval key.
The debug memory allocation or dmalloc library is a drop-in replacement for the system's native memory management routines. It provides powerful debugging facilities which are configurable at runtime. These facilities include such things as memory-leak tracking, fence-post write detection, file/line number reporting, and general logging of statistics. The library has been run successfully on a wide variety of operating systems. It also provides support for the debugging of threaded programs.
IDebug is an advanced debugging framework for Java. It provides the standard core debugging and specification constructs such as assertions, debug levels and categories, stack traces, and specialized exceptions. Debugging functionality can be fine-tuned to a per-thread and/or a per-class basis, debugging contexts can be stored and recovered from persistent store, and several aspects of the debugging run-time are configurable at the meta-level.
JUnit is a Java testing framework. Since testing is not closely integrated with development, it prevents you from measuring the progress of development. You can't tell when something starts working or when something stops working. Using JUnit you can cheaply and incrementally build a test suite that will help you measure your progress, spot unintended side effects, and focus your development efforts.
JUnitX is a module on top of JUnit 3.2 by Kent Beck and Erich Gamma. It is a well-designed Java testing framework to write tests in the style of Extreme Programming. It allows you access to private and protected classes, methods, and fields in order to write improved and well-organized test cases. JUnit and an old version of JUnitX are also part of Together since version 5.5.
LANforge is a unified multi-protocol network traffic generation and WAN emulation application. It allows users to generate real world customer traffic in a controllable manner. The WAN emulator allows the injection of latency and other network oddities like dropped, duplicated, and re-ordered packets. LANforge includes a drag-and-drop virtual network builder that supports virtual routers, WAN links, traffic-generating nodes, and more. It provides a scriptable command line interface with Perl libraries as well as a graphical user interface.
