3 1. What are we trying to accomplish? 1. What are we trying to accomplish?  In this project, we are trying to address a way to test autonomic systems.  In order to create an application simple enough to test autonomic characteristics, we have come up with the idea of an autonomic container.

4 2. What is an Autonomic Container?  An Autonomic Container is a data structure that can be dynamically changed during run time.  A container a is structure used for object holding or collecting.  It must contain the four characteristics of Autonomic Computing: self healing, self protecting, self optimizing, and self configuring.

5 Testing within the Autonomic Manager  In order to properly test an Autonomic Container, we would like to implement a test set up in the autonomic element.  Taking knowledge already known about Autonomic Computing, we would like to add to the existing architecture.

13 3. Architecture of an Autonomic Container

14 Our Contribution  We are in charge of working on the managed element and the test executer.  For the Autonomic Container, we need to be able to make a copy of the managed element that will run parallel to the original element.  During runtime, the copy of the element will be tested on and updated as the original element is updated.

15  When a change is requested, the contents of the managed element copy are switched with the original element.

16 Implementation of an Autonomic Container  In order to implement the Autonomic Container, we need a simple application to run.  The simple application we have chosen to run is a stack.  This stack is a simple data structure written in Java that contains the functions push, pop, and resize.

17 4. What testing tools are being used for this project?  To test this project we will be using two testing tools. They are JUnit and the Rational Functional Tester.

18 What is JUnit?  JUnit is a unit testing framework for Java.  JUnit is part of a family of unit testing frameworks [1]  PyUnit (Python language version)  fUnit (Fortran language version)  CPPUnit (C++ language version)  Collectively referred to as xUnit frameworks.

19 What is Rational Functional Tester?  An automated functional and regression testing tool for testing and GUI development that can be used with Java and Microsoft VisualStudio  Can be used with web-based applications
