/** @short  Check the interface method XComponentLoader.loadComponentFromURL()

    @descr  A prerequisite for this test is a server which allows access to files
            that will be loaded via three different access methods:
            <ul>
                <li>1. nfs (mounted directory / mapped network drive)</li>
                <li>2. ftp</li>
                <li>3. http</li>
            </ul>
            <p>
            The test will look for a list of files from the <i>TestDocumentPath</i>
            on and load these files from the mounted directory, via ftp and http.
            The parameters for this have to be "ftp_access" and "http_access".
            If they are not given, tests for ftp and http will fail.

    @todo   We need a further test for accessing UNC paths on windows!
