Testing Camel REST DSL Consumer Template

Question

I have the following code:

import org.apache.camel.builder.RouteBuilder;
import org.apache.camel.model.rest.RestBindingMode;

public class OrderNumberRouteBuilder extends RouteBuilder {

    @Override
    public void configure() throws Exception {
        restConfiguration().component("servlet").bindingMode(RestBindingMode.json)          
            .dataFormatProperty("prettyPrint", "true")
            .contextPath("suppliera/rest").port(8080);

        rest("/ordernumber").description("ordernumber rest service")
            .consumes("application/json").produces("application/json")

            .get("/{id}").description("get ordernumber").outType(ServiceResponse.class)
            .to("bean:orderNumberService?method=getOrderNumber(${header.id})");
    }
}

How can I use JUnit to test this code? Can CamelTestSupport handle it?

I want to create a test like:

@Produce(------myendpoint----) 
protected ProducerTemplate testProducer; 

public void mytest(){
testProducer.requestBody("foo");
}

how can I mock that? what I put in -----myendpoint---- to reference that route?

Answer 1

As a possible solution, you can set the URI for your REST route and use that URI in your junit test. In order to do so, you need to switch RestDefinition to RouteDefinition by calling route method, and then you can call the from method and set the uri argument. Example using direct endpoint:

    rest("/ordernumber").description("ordernumber rest service")
    .consumes("application/json").produces("application/json")
    .get("/{id}").description("get ordernumber").outType(ServiceResponse.class)
    .route().from("direct:myendpoint")
    .to("bean:orderNumberService?method=getOrderNumber(${header.id})");

In your junit class, you can then type:

@Produce(uri = "direct:myendpoint")
protected ProducerTemplate testProducer;

Hope this helps.
