* Distributed Framework A graphical console allows multiple load injectors to be monitored and controlled, and provides centralised script editing and distribution.

JMock is a library that supports test-driven development1 of Java2 code with mock objects3.
Mock objects help you design and test the interactions between the objects in your programs.
The jMock library:
* makes it quick and easy to define mock objects, so you don't break the rhythm of programming.
* lets you precisely specify the interactions between your objects, reducing the brittleness of your tests.
* works well with the autocompletion and refactoring features of your IDE
* plugs into your favourite test framework
* is easy to extend.
