Question

I use Mule 3.x

I have a code that tests MuleClient connectivity.

This test is ok and works proper way:

public void testHello() throws Exception
    {
        MuleClient client = new MuleClient(muleContext);
        MuleMessage result = client.send("http://127.0.0.1:8080/hello", "some data", null);
        assertNotNull(result);
        assertNull(result.getExceptionPayload());
        assertFalse(result.getPayload() instanceof NullPayload);

        //TODO Assert the correct data has been received
        assertEquals("hello", result.getPayloadAsString());
    }

But this tes is not ok – it fail with an connection exceptions:

public void testHello_with_Spring() throws Exception {

    MuleClient client = new MuleClient("mule-config-test.xml");
    client.getMuleContext().start();

    //it fails here
    MuleMessage result = client.send("http://127.0.0.1:8080/hello", "some data", null);
    assertNotNull(result);

    assertNull(result.getExceptionPayload());
    assertFalse(result.getPayload() instanceof NullPayload);

    //TODO Assert the correct data has been received
    assertEquals("hello", result.getPayloadAsString());
}

The ‘mule-config-test.xml’ is used in both tests, the path for this file is ok, i checked.

This is error message I have in the end:

Exception stack is:
1. Address already in use (java.net.BindException) java.net.PlainSocketImpl:-2 (null)
2. Failed to bind to uri “http://127.0.0.1:8080/hello” (org.mule.transport.ConnectException)

I think the problem is in what you’re not showing: testHello_with_Spring() is probably executing while Mule is already running. The second Mule you’re starting in it then port-conflicts with the other one.

Are testHello() and testHello_with_Spring() in the same test suite? If yes, seeing that testHello() relies on an already running Mule, I’d say that would be the cause of port conflict for testHello_with_Spring().
