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.
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.
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.
Load is a utility for Web application and SOAP-based Web services performance and scalability testing. It features a scripting language and a library of test objects for the creation of intelligent agents that drive the Web application or SOAP-based Web service. Running hundreds of agents concurrently shows how your software performs in production environments. Load is a Java application that runs on Linux, Solaris, NT, Win2000, and Macintosh. While Load continues to be maintained, the next generation is the TestMaker program.
LogiTest is a Java application for functional and regression testing of Web sites. It currently supports GET and POST methods, HTTPS, cookies, browser history, XML formatted tests, simple Testlet API for writing new tests, user-defined HTTP headers and parameters, and regular expressions. Tests are recorded and played back through a easy-to-use GUI and can be stored and loaded from XML files.
XPTest for Together provides two patterns and a module to allow the fast development of test cases. The TestCase pattern creates a class which has to be customized to contain test methods for a given class containing business methods. Using the TestPackage pattern, a class collecting all TestCases recursively can be created. The execution module allows one to start a Swing or AWT GUI to test single classes or packages in any granularity. It depends on JUnit by Kent Beck and Erich Gamma, and is designed to significantly speed up the development of Extreme Programming-inspired tests within the Together UML modeling tool and wanna-be-IDE. Since version 5.5, XPTest is also part of the Together distribution.
Lloyd's Java Shell is a java scripting tool (it could read and execute java-like statement from any input stream) that could easily be plugged into an application and modify its object - so it is also a configuration tool. It is also a good test tool, as you could easily use it to test any feature of your new object.
