How do I test that a node was executed in a Camel route?

Question

I have a Camel route defined as follows:

@Component
public class MyRoute extends RouteBuilder {
        
    @Override
    public void configure() {       

        onException(BeanValidationException.class)
        .setBody(simple("${exception}"))
        .to("{{route.mail}}")
        .continued(true); // there's a validation issue just notify via mail and continue processing 
        
        // main flow
        from("{{route.from}}")
        .unmarshal(new BindyCsvDataFormat(MyClass.class))
        .to("{{route.mail}}")
        .to("{{route.to}}");
    }
}

In my test case, how can I differentiate .to("{{route.mail}}") in the onException flow vs .to("{{route.mail}}") in the main flow?

I want to write a test that verifies the .to("{{route.mail}}") in the onException(BeanValidationException.class) is called. I can verify that route.mail is called twice as follows:

@SpringBootTest(properties = {
        "route.from = direct:from",
        "route.mail = mock:mail",
        "route.to = mock:to"
})
@CamelSpringBootTest
class RouteTest {
    
    @Autowired
    private ProducerTemplate template;
    
    @EndpointInject("mock:to")
    private MockEndpoint mockTo;
    
    @EndpointInject("mock:mail")
    private MockEndpoint mockMail;

    @Test
    @DirtiesContext 
    void beanValidationException() throws InterruptedException {
        
        mockMail.expectedMessageCount(2);
        template.sendBody("{{route.from}}", "dataToCauseBeanValidationException");
        
        mockMail.assertIsSatisfied();
    }
}

But I'm not sure how to test which route.mail was called.
