URL: https://github.com/apache/camel-quarkus/issues/4362#issuecomment-1369885091

   The problem is caused by the usage of the `javax.enterprise.inject.Produces` 
in the test (line 
https://github.com/guhilling/camel-quarkus-demos/blob/main/src/test/java/de/hilling/camel/SampleRouteBuilderTest.java#L35).
 
   
   The `CamelQuarkusTestSupport` aims to help replace Camel's CamelTestSupport 
tests. `@Produce` can not be used with them and CamrlQuarkusTestSupport does 
not work with them easily. Using @Produce to create routeBuilders is not 
recommanded.
   
   Here are some problems caused by the differences of lifecycle in Camel and 
CamelQuarkus:
   
   • Application is started once for all the tests together. Therefore all 
@Produces methods are applied together - in case there were several Test 
classes each producing its own route builder - this will force application to 
create all routes at the start (even if they are not necessary for the first 
test class)
   • Support of `CamelTestSupport` like tests forces camel-quarkus to emulate 
several lifecycle actions without stopping the application. Which leads for 
example to stopping and removing routes and creating them again for another 
test method/classes.
   • . Fully supported style of registering RouteBuilders is to use overriding 
method. 
   
   
   Please replace following code (lines 
https://github.com/guhilling/camel-quarkus-demos/blob/main/src/test/java/de/hilling/camel/SampleRouteBuilderTest.java#L33-L39)
   
   ```
       @Configuration
       public static class TestConfig {
           @Produces
           RoutesBuilder route() {
               return new SampleRouteBuilder();
           }
       }
   ```
   
   with 
   
   ```
       @Override
       protected RouteBuilder createRouteBuilder() {
           return new SampleRouteBuilder();
       }
   ```
   
   and the tests will finish successfully.
   
   I've added the suggestion to not use @Produce with RouteBuilders int the 
documentation.
