JMeter - Load and Performance tester
JMeter is a pure Java desktop application designed to load test functional behavior and measure performance. It 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.
It could do performance test for Web application, Web services, Database, LDAP, JMS, Mail. It produces graphical analysis of test report. Test results could be cached offline. Data analysis and visualization plugins allow great extensibility.

Multi-Mechanize is an framework for web performance and load testing. It allows you to run simultaneous python scripts to generate load (synthetic transactions) against a web site or web service. You programmatically create test scripts to simulate virtual user activity. Your scripts will then generate HTTP requests to intelligently navigate a web site or send requests to a web service.
Pylot is a free open source tool for testing performance and scalability of web services. It runs HTTP load tests, which are useful for capacity planning, benchmarking, analysis, and system tuning. Pylot generates concurrent load (HTTP Requests), verifies server responses, and produces reports with metrics. Tests suites are executed and monitored from a GUI or shell/console.
OpenSTA is a distributed software testing architecture designed around CORBA. The current toolset has the capability of performing scripted HTTP and HTTPS heavy load tests with performance measurements from Win32 platforms. Results and statistics are collected during test runs by a variety of automatic and user controlled mechanisms. These can include scripted timers, SNMP data, Windows Performance Monitor stats and HTTP results & timings.
The Grinder is a Java load testing framework that makes it easy to run a distributed test using many load injector machines. Load test anything that has a Java API. This includes common cases such as HTTP web servers, SOAP and REST web services, and application servers (CORBA, RMI, JMS, EJBs), as well as custom protocols.
soapUI is the world leading Open Source Functional Testing Tool, mainly it is used for Web Service Testing. Its features include Web service testing, Load testing, Functional testing, SOAP recording, Service mocking, Integrated reporting and lot more.
The WebLOAD Open Source Load Generation Engine is an open source project sponsored by RadView Software. This project is intended for ISVs, SIs and software developers who need to integrate a professional load generation engine into their applications.
Linux Desktop Testing Project is aimed at producing high quality test automation framework (using GNOME / Python) and cutting-edge tools that can be used to test Linux Desktop and improve it. It uses the Accessibility libraries to poke through the application's user interface. We strive to help in building a quality desktop.
Why would I use this rather than tools like jMeter or jUnitPerf? There are a variety of different performance testing tools available in the Java world, some are more useful than others for different tasks, but we have run into a number of limitations. We have found that both load testing and micro-benchmarking tools are not designed with generalized performance benchmarking in mind. To be fair, they also don't intend to be generalized benchmarking tools, which is good. A benchmark is not necess
Selenium is a suite of tools such as Selenium IDE, Selenium Remote Control and Selenium Grid to test the web application. Selenium IDE is an integrated development environment for Selenium scripts. It is implemented as a Firefox extension, and allows you to record, edit, and debug tests. It supports record and playback.
