Junit Tests and ErraiBus

Version 1

Created by davidka on Apr 25, 2012 9:42 AM. Last modified by davidka on Apr 25, 2012 9:59 AM.

Hi,

I followed your explanations under 'https://github.com/errai/errai/blob/master/errai-bus/src/test/java/org/jboss/errai/bus/client/tests/BusCommunicationTests.java', to perfrom a GWT Unit Tests with the usage of the erraibus.

All my tries are ended up in an error. It seems, that the ErraiBus could not be initialized propperly ??.

Find below the code of the test class and the resulting stacktrace. I set the parameter -Dorg.jboss.errai.bus.do_long_poll=false and the main and test dirs were added to the runtime path propperly.

Could you please advice?

public class OnFieldSearchPresenterGWTTest extends AbstractErraiTest {

@Override

public String getModuleName() {

return "net.xxxxx.tracking.tracking";

}

@Test

public void bindTest(){

testBasicRoundTrip() ;

}

public void testBasicRoundTrip() {

runAfterInit(new Runnable() {

public void run() {

bus.subscribe("ShipmentResultReceiver", new MessageCallback() {

@Override

public void callback(Message message) {

List<Shipment> result = message.get(List.class, ShipmentServiceParts.RESULT);

retrieveShipments(result);

}

});

MessageBuilder.createMessage()

.toSubject("ShipmentService") // (1)

.with(ShipmentServiceParts.ONEFIELDSEARCH, "lalala")

.noErrorHandling() // (3)

.sendNowWith(bus); // (4)

}

});

}

private void retrieveShipments(List<Shipment> result) {

StringBuilder sb = new StringBuilder();

sb.append("Found " + result.size() + " Shipments" + "\n\n");

ListIterator<Shipment> lit = result.listIterator();

while (lit.hasNext()) {

Shipment sh = lit.next();

sb.append(sh.toString() + "\n");

}

System.out.println(sb.toString());

}

REMEMBER! Bus tests will not succeed if:

1. You do not run the unit tests with the flag: -Dorg.jboss.errai.bus.do_long_poll=false

2. You do not have the main and test source directories in the runtime classpath
