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.
3
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.
4
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.

Application
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.
14
 When a change is requested, the contents
of the managed element copy are
switched with the original element.
15
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.
16
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.
17
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.
18
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
