the class GwtExecuteJavaScriptElementUtilsTest method testReturnChannel_passedToExecJavaScript_messageSentToServer.

public void testReturnChannel_passedToExecJavaScript_messageSentToServer() {
    ApplicationConfiguration applicationConfiguration = new ApplicationConfiguration();
    applicationConfiguration.setApplicationId("test");
    // Pass a number to the channel
    String expression = "$0(2)";
    int expectedNodeId = 10;
    int expectedChannelId = 20;
    int[] runCountHolder = { 0 };
    ExecuteJavaScriptProcessor processor = new ExecuteJavaScriptProcessor(new Registry() {

        {
            set(StateTree.class, new StateTree(this));
            set(ApplicationConfiguration.class, applicationConfiguration);

                @Override
                public void sendReturnChannelMessage(int stateNodeId, int channelId, JsonArray arguments) {
                    assertEquals(expectedNodeId, stateNodeId);
                    assertEquals(expectedChannelId, channelId);
                    assertEquals("Args array should contain the value passed to the channel function", "[2]", arguments.toJson());
                    runCountHolder[0]++;
                }
            });
        }
    });
    JsonArray serializedChannel = Json.createArray();
    serializedChannel.set(0, JsonCodec.RETURN_CHANNEL_TYPE);
    serializedChannel.set(1, expectedNodeId);
    serializedChannel.set(2, expectedChannelId);
    JsonArray invocation = Json.createArray();
    // Assign channel as $0
    invocation.set(0, serializedChannel);
    invocation.set(1, expression);
    JsonArray invocations = Json.createArray();
    invocations.set(0, invocation);
    processor.execute(invocations);
    assertEquals(1, runCountHolder[0]);
}
