/**
 * This class is intended for use with testing against the Python
 * <a href="http://www.tavendo.de/autobahn/testsuite.html">AutoBahn test suite</a>.
 *
 * Autobahn installation documentation can be found <a href="http://autobahn.ws/testsuite/installation">here</a>.
 *
 * <h3>How to run the tests on Linux/OSX.</h3>
 *
 * <p>01. Install AutoBahn: <tt>sudo easy_install autobahntestsuite</tt>.  Test using <tt>wstest --help</tt>.
 *
 * <p>02. Create a directory for test configuration and results: <tt>mkdir ~/autobahn</tt> <tt>cd ~/autobahn</tt>.
 *
 * <p>03. Create <tt>fuzzing_client_spec.json</tt> in the above directory
 * {@code
 * {
 *    "options": {"failByDrop": false},
 *    "outdir": "./reports/servers",
 *
 *    "servers": [
 *                 {"agent": "Netty4",
 *                  "url": "ws://localhost:9000",
 *                  "options": {"version": 18}}
 *               ],
 *
 *    "cases": ["*"],
 *    "exclude-cases": ["9.*"],
 *    "exclude-agent-cases": {}
 * }
 * }
 * Note that we disabled the <strong>9.*</strong> tests for now as these fail.
 *
 * <p>04. Run the <tt>AutobahnServer</tt> located in this package. If you are in Eclipse IDE, right click on
 * <tt>AutobahnServer.java</tt> and select Run As > Java Application.
 *
 * <p>05. Run the Autobahn test <tt>wstest -m fuzzingclient -s fuzzingclient.json</tt>.
 *
 * <p>06. See the results in <tt>./reports/servers/index.html</tt>
