TestBed.java: The TestBed.java file is our development and testing class. It has code in it that takes advantage of almost every single aspect of ECS so that we can stress test the framework and look for errors. Please note that you will need to link against the ../lib/xerces.jar file in order to compile and use it. If it does not compile or run properly for you, then please do not take this as a sign that ECS is not working. Chances are that this file is either broken or is not in a working state for some reason or another. You can use this class to get some working example code on how to build elements using ECS. We suggest that you create your own testing class and then copy/paste code from this class to your own class to do your testing/learning.
