Apache Camel Integration Test - NotifyBuilder - esb

Question

I am writing integration tests to test existing Routes. The recommended way of getting the response looks something like this (via Camel In Action section 6.4.1):
public class TestGetClaim extends CamelTestSupport {
#Produce(uri = "seda:getClaimListStart")
protected ProducerTemplate producer;
#Test
public void testNormalClient() {
NotifyBuilder notify = new NotifyBuilder(context).whenDone(1).create();
producer.sendBody(new ClientRequestBean("TESTCLIENT", "Y", "A"));
boolean matches = notify.matches(5, TimeUnit.SECONDS);
assertTrue(matches);
BrowsableEndpoint be = context.getEndpoint("seda:getClaimListResponse", BrowsableEndpoint.class);
List<Exchange> list = be.getExchanges();
assertEquals(1, list.size());
System.out.println("***RESPONSE is type "+list.get(0).getIn().getBody().getClass().getName());
}
}
The test runs but I get nothing back. The assertTrue(matches) fails after the 5 second timeout.
If I rewrite the test to look like this I get a response:
#Test
public void testNormalClient() {
producer.sendBody(new ClientRequestBean("TESTCLIENT", "Y", "A"));
Object resp = context.createConsumerTemplate().receiveBody("seda:getClaimListResponse");
System.out.println("***RESPONSE is type "+resp.getClass().getName());
}
The documentation is a little light around this so can anyone tell me what I am doing wrong with the first approach? Is there anything wrong with following the second approach instead?
Thanks.
UPDATE
I have broken this down and it looks like the problem is with the mix of seda as the start endpoint in combination with the use of a recipientList in the Route. I've also changed the construction of the NotifyBuilder (I had the wrong endpoint specified).
If I change the start endpoint to
direct instead of seda then the test will work; or
If I comment out the recipientList
then the test will work.
Here's a stripped down version of my Route that reproduces this issue:
public class TestRouteBuilder extends RouteBuilder {
#Override
public void configure() throws Exception {
// from("direct:start") //works
from("seda:start") //doesn't work
.recipientList(simple("exec:GetClaimList.bat?useStderrOnEmptyStdout=true&args=${body.client}"))
.to("seda:finish");
}
}
Note that if I change the source code of the NotifyTest from the "Camel In Action" source to have a route builder like this then it also fails.

Answer 1

Try to use "seda:getClaimListResponse" in the getEndpoint to be sure the endpoint uri is 100% correct

Answer 2

FWIW: It appears that notifyBuilder in conjunction with seda queues are not quite working: a test class to illustrate:
public class NotifyBuilderTest extends CamelTestSupport {
// Try these out!
// String inputURI = "seda:foo"; // Fails
// String inputURI = "direct:foo"; // Passes
#Test
public void testNotifyBuilder() {
NotifyBuilder b = new NotifyBuilder(context).from(inputURI)
.whenExactlyCompleted(1).create();
assertFalse( b.matches() );
template.sendBody(inputURI, "Test");
assertTrue( b.matches() );
b.reset();
assertFalse( b.matches() );
template.sendBody(inputURI, "Test2");
assertTrue( b.matches() );
}
#Override
protected RouteBuilder createRouteBuilder() throws Exception {
return new RouteBuilder() {
#Override
public void configure() throws Exception {
from(inputURI).to("mock:foo");
}
};
}
}
