The Grinder, a Java Load Testing Framework
What is The Grinder?The Grinder is a JavaTM load testing framework that makes it easy to run a distributed test using many load injector machines. It is freely available under a BSD-style open-source license.
The latest news, downloads, and mailing list archives can be found on SourceForge.net.
Key features
Generic Approach 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.
Flexible Scripting Test scripts are written in the powerful Jython and Clojure languages.
Distributed Framework A graphical console allows multiple load injectors to be monitored and controlled, and provides centralised script editing and distribution.
Mature HTTP Support Automatic management of client connections and cookies. SSL. Proxy aware. Connection throttling. Sophisticated record and replay of the interaction between a browser and a web site.
Dynamic Scripting
Test scripts are written using a dynamic scripting language, and specify the tests to run. The default script language is Jython, a Java implementation of the popular Python language.
The script languages provide the following capabilities:Test any Java code
The Grinder 3 allows any code (Java, Jython, or Clojure) code to be encapsulated as a test. Java libraries available for an enormous variety of systems and protocols, and they can all be exercised using The Grinder.Dynamic test scripting
The Grinder 2 worker processes execute tests sequentially in a fixed order, and there is limited support in some of the The Grinder 2 plug-ins for checking test results. The Grinder 3 allows arbitrary branching and looping and makes test results directly available to the test script, allowing different test paths to be taken depending on the outcome of each test.
The Grinder 2 HTTP plug-in's string bean feature provides simple support for requests that contain dynamic data. The Grinder 3 can use the full power of Jython or Clojure to create dynamic requests of arbitrary complexity.
The powerful scripting removes the need to write custom plug-ins that extend The Grinder engine. Although plug-ins are no longer responsible for performing tests, they can still be useful to manage objects that the tests use. For example, the standard HTTP plug-in manages a pool of connections for each worker thread, and provides an HTTPRequest object that makes use of these connections.
