Writing a apache camel test case but getting this error

Question

am writing a camel route test case but am getting this issue, have also included the camel route. Have debugged looks like the object is flowing through properly but on my assertion it seems to fail...

java.lang.AssertionError: mock://seda:processMessage?blockWhenFull=true Received message count. Expected: <1> but was: <0>

(below is the camel route )

        .endCircuitBreaker()
        .endChoice()

        .log("Final :- ${body}")
        .end();

Edit :

I modified the class like below by adding "mock:" to my route but is there a way to go around this? seems like it is not sending to the proper endpoint without me changing and adding the "mock:" value to where it is sending

Edit :

I added in this peice of code - to try to use adviceWith in my test class. I am calling the endpoint like so

    getMockEndpoint("mock:"+Endpoints.SEDA_PROCESS_ENDPOINT).expectedBodiesReceived(costIQPayloadString());

But am getting the error

Cannot advice routes as there are no routes

   @Test
    public void testReplaceFrom() throws Exception {
        AdviceWith.adviceWith(context, Endpoints.SEDA_PROCESS_ENDPOINT, a -> {
            a.mockEndpoints("mock:"+Endpoints.SEDA_PROCESS_ENDPOINT);
        });
        }

Here is an example with route advice. Note that you probably will need to do some cleanup after your test to reset the data!

A bit older code in kotlin but should get the idea:

@SpringBootTest
class YourTest {
    @Autowired
    private lateinit var camelContext: CamelContext

    @Autowired
    private lateinit var template: ProducerTemplate

    // No MockEndpoints

    ...

    @Throws(Exception::class)
    private fun configureMockEndpoint() {
        AdviceWith.adviceWith(
            camelContext,
            "yourRouteId"
        ) { adviceWithRouteBuilder: AdviceWithRouteBuilder ->
            adviceWithRouteBuilder.replaceFromWith("direct:test")
        }
    }

    @Test
    fun yourTest() {
        configureMockEndpoint()
        template.sendBodyAndHeader("direct:test", "Your headers", """
            your content
        """.trimIndent())
        // asserts
        // cleanups
    }

}
