I'm trying to use JUnit to test the interaction between an XML-RPC server and an XML-RPC client I have written. First thing, I'm setting up the client and the server in the setUp() method, then start the server. Finally, since I do not want the server to still be up and running after all the tests are completed, I'm trying to shutdown it in the tearDown() method.

			

			public class TestXmlRpc extends TestCase {
			

			private XmlRpcMyServer server;
			

			private XmlRpcMyClient client;
			

			

			public void setUp() {
			

			server = new XmlRpcMyServer();
			

			client = new XmlRpcMyClient();
			

			try {
			

			server.start();
			

			} catch (Exception e) {
			

			e.printStackTrace();
			

			}
			

			}
			

			

			// do some tests
			

			

			public void tearDown() {
			

			server.shutdown();
			

			}
			

			}
			

		

As I have undestand it, the JUnit framework calls setUp() and tearDown() for each test in the class. So, I end up building and starting an XmlRpcMyServer for as many times as the number of tests in the class, generating a random number of java.io.IOExceptions (Address in use: JVM_Bind) since the severs try to bind themselves to the same port.

An idea could be to start and shutdown a server in each method: not only I am not sure this would work, but also I do not understand why I can not use the same server for all the test requests.

Has anyone running in a similar problem, and/or can suggest a solution?
