/**
* ServletTester is not best practice and may be deprecated and eventually
* removed in future Jetty versions.
* ServletTester is a just a wrapper around a {@link ServletContextHandler},
* with a {@link LocalConnector} to accept HTTP/1.1 requests, so there is no
* value that this class adds to already existing classes.
* Replace its usages with:
*
* Server server = new Server();
* LocalConnector connector = new LocalConnector(server);
* server.addConnector(connector);
* ServletContextHandler context = new ServletContextHandler(server, "/contextPath");
* // Configure the context here.
* server.start();
*
* You can configure the context by adding Servlets and Filters, attributes,
* etc. even after it has been started.
* Use {@link HttpTester} and {@link LocalConnector} to make HTTP/1.1 requests,
* in this way:
*
* // Generate the request.
* HttpTester.Request request = HttpTester.newRequest();
* request.setMethod("GET");
* request.setURI("/contextPath/servletPath");
* request.put(HttpHeader.HOST, "localhost");
* ByteBuffer requestBuffer = request.generate();
*
* // Send the request buffer and get the response buffer.
* ByteBuffer responseBuffer = connector.getResponse(requestBuffer);
*
* // Parse the response buffer.
* HttpTester.Response response = HttpTester.parseResponse(responseBuffer);
* assert response.getStatus() == HttpStatus.OK_200;
*
* Alternatively, you can use raw strings for requests and responses,
* but you must be sure the request strings are in the correct HTTP/1.1 format:
*
* String rawRequest = "" +
* "GET /contextPath/servletPath HTTP/1.1\r\n" +
* "Host: localhost\r\n" +
* "\r\n";
* String rawResponse = connector.getResponse(rawRequest);
* HttpTester.Response response = HttpTester.parseResponse(rawResponse);
*
