How to mock Apache Camel Route before CamelContext is started in CamelSpringBootTest

Maybe a rather uncommon issue, but I'd like to mock certain Camel routes, in the JUnit setup method

@BeforeEach
void setUp() {
}

before the

@Override
public void configure() throws Exception {

}

is executed, which seems to happen, as soon as the CamelContext is autowired

@Autowired
protected CamelContext camelContext;

What do I need to do, to prevent autostarting of the Camel Context, in order to be able to mock my routes in the setup method and start it manually?

This post is old but I don't like unanswered questions. So declare a MockEnpoint like so:

@EndpointInject("mock:mockExampleQueue")
MockEndpoint mockExampleQueue;

and add it to the routes at initialisation:

@BeforeAll
void setUpClass() throws Exception { 
  camelContext.addRoutes(
    new RouteBuilder() {
      @Override
      public void configure() {
        from("jms:queue:" + EXAMPLE_QUEUE)
          .to(mockExampleQueue);
        }
      });
  ..
}

EXAMPLE_QUEUE ist the queue you want to observe and that you must have definded in your code. Than make expectations:

mockExampleQueue.setExpectedCount(2);
mockExampleQueue.setResultWaitTime(20000);

and send a message or do what ever to let the routes do their expected jobs. Finally check that your expectations are fulfilled:

mockExampleQueue.assertIsSatisfied();

In an optional step you may check further details:

List<Exchange> receivedExchanges = mockExampleQueue.getReceivedExchanges();
...

You can enable advice with in the unit test - then you need to start Camel manually.
