Starting and stopping a Jetty server between JUnit tests

Question

I'm trying to simulate tests of various run-throughs of my program, setting up a Jetty server in a @Before method and closing it down in an @After.

My first test will run successfully, but upon attempting to POST data in following tests com.sun.jersey.api.client.ClientHandlerException: java.net.SocketException: Software caused connection abort: recv failed occurs. Is there any way I can get my Server (and Client?) to shut down cleanly between tests?

My Before and After code is as follows:

@Before
public void startServer() {
    try {
        server = new Server(8080);
        ServletContextHandler root = new ServletContextHandler(server, "/ingest", ServletContextHandler.SESSIONS);

        root.addServlet(new Servlet(), "/*");

        server.start();

        client = new Client();
        client.setChunkedEncodingSize(16 * 1024);

        FileInputStream stream = new FileInputStream(testFile);
        try {
            client.resource(uri).type(MediaType.APPLICATION_OCTET_STREAM).post(stream);
        } catch (Exception e) {
            e.printStackTrace();
        } finally {
            Closeables.closeQuietly(stream);
            client.destroy();
        }
    } catch (Exception e) {
        e.printStackTrace();
        fail("Unexpected Exception when starting up server.");
    }
}

@After
public void shutDown() {
    if (output.exists()) {
        output.delete();
    }
    try {
        server.stop();
    } catch (Exception e) {
        e.printStackTrace();
    }
}

Best practice in testing scenarios is to not hard code the port. That only leads to conflicts when running elsewhere, especially on CI systems that have even a moderate load or variety of projects.

in Jetty 9 (same idea in 6, 7, 8)

_server = new Server();
_connector = new ServerConnector(_server);  
_server.setConnectors(new Connector[] { _connector });
_server.start();
int port = _connector.getLocalPort();
