*  <li><code> createCommandIdentifier()</code></li>
*  <li><code> execute()</code></li>

*  <li> <code>'XCommandProcessor.AbortCommand'</code> <b>optional</b>
*   (of type <code>com.sun.star.ucb.Command</code>):
*   specify command to abort in <code>abort()</code> test.

*   command is used.</li>
* <ul> <p>
* The following predefined files needed to complete the test:
* <ul>
*  <li> <code>poliball.gif</code> : this file is required in case
*   if the relation <code>'XCommandProcessor.AbortCommand'</code>
*   is not specified. This file is used by 'GlobalTransfer'
