[CAMEL-15402] Spring components extending RouteBuilder not added to CamelContext during tests

• Type: Bug
• Status: Resolved
• Priority: Minor
• Resolution: Won't Fix
• Affects Version/s: 3.4.2
• Component/s: camel-spring-boot, camel-test

Environment

Spring Boot 2.3.2, JUnit5 that comes with the former, Java 11, Maven 3.6

First time I spotted the issue was Dec 2017 in Camel 2.20 so it's not in some freshly changed part of the project.

Description

Having written a couple of tests for pieces of routes within a Camel application, I have noticed that testing routes defined by components annotated with @Consume("direct:xyz") work quite well, but components that extend the class org.apache.camel.builder.RouteBuilder suffer from the following issue.

The component scanning by Spring encounters these components fine. If they are autowired in the test, then those fields have a value as expected. But when the test route has to invoke it, then delivery fails throwing a DirectConsumerNotAvailableException.

The work-around is to invoke camelContext.addRoutes(autowiredInstance) in the test, which should not be necessary and clutters up the test code.
