Camel testing - java.lang.IllegalArgumentException: defaultEndpoint must be specified

I am trying to create testcases for my camel route using http://camel.apache.org/mock.html . I need to verify the the processors in the route. But the simple test is not working for me.

public class CamelRouteTest extends CamelTestSupport {

@Override
public String isMockEndpointsAndSkip() {
// override this method and return the pattern for which endpoints to mock,
// and skip sending to the original endpoint.
return "mock:result";
}

@Test
public void verifyMessageCount() throws Exception {
template.sendBody("Test");
getMockEndpoint("mock:result").expectedMessageCount(1);
assertMockEndpointsSatisfied();
}

@Override
protected RouteBuilder createRouteBuilder() throws Exception {
return new RouteBuilder() {
@Override
public void configure() throws Exception {
from("direct:start").to("mock:result");
}
};
}
}

Answer

The template.sendBody("Test") try to send Test to the default endpoint. As in your code this is not configured it fails.

You could:

  • specify which endpoint to use

    template.sendBody("direct:start", "Test");
    
  • get an endpoint from the context and set it as the default endpoint

    Endpoint endpoint = context.getEndpoint("direct:start");
    template.setDefaultEndpoint(endpoint);
    template.sendBody("Test");
