The same detection mechanism and combined interface extends to the other Jackson data formats (avroJackson, protobufJackson, and jacksonXml).

=== camel-test-junit6, camel-test-main-junit6, camel-test-spring-junit6

camel-test-junit6 was introduced in 4.17.0 - and in 4.19.0 all of the camel components have moved to using it for testing as part of the upgrade to Spring Boot 4.0. Migration to JUnit 6 camel-test-* components is optional - the camel-test-junit5 is still available and is pinned to JUnit 5 use. Migrating to camel-test-junit6 has the benefit of better alignment with Spring Boot 4.0 (using camel-spring-boot as a runtime). If you are using camel-test-junit5 and would like to move to camel-test-junit6, you can change from:

Before:
[source,xml]
----
<dependency>
<groupId>org.apache.camel</groupId>
<artifactId>camel-test-junit5</artifactId>
<version>${camel.version}</version>
<scope>test</scope>
</dependency>
----

After:
[source,xml]
----
<dependency>
<groupId>org.apache.camel</groupId>
<artifactId>camel-test-junit6</artifactId>
<version>${camel.version}</version>
<scope>test</scope>
</dependency>
----

You will also need to change any imports of classes in `org.apache.camel.test.junit5.*` to `import org.apache.camel.test.junit6.*`.

Similarly, for camel-test-main-junit5 you would need to change any imports of classes in `org.apache.camel.test.main.junit5.*` to `org.apache.camel.test.main.junit6.*`, and the dependency in your pom.xml would change from:

Before:
[source,xml]
----
<dependency>
<groupId>org.apache.camel</groupId>
<artifactId>camel-test-main-junit5</artifactId>
<version>${camel.version}</version>
<scope>test</scope>
</dependency>
----

After:
[source,xml]
----
<dependency>
<groupId>org.apache.camel</groupId>
<artifactId>camel-test-main-junit6</artifactId>
<version>${camel.version}</version>
<scope>test</scope>
</dependency>
----

Finally, for camel-test-spring-junit5 any imports would change from `org.apache.camel.test.spring.junit5.*` to `import org.apache.camel.test.spring.junit6.*` and the dependency change would be :

Before:
[source,xml]
----
<dependency>
<groupId>org.apache.camel</groupId>
<artifactId>camel-test-spring-junit5</artifactId>
<version>${camel.version}</version>
<scope>test</scope>
</dependency>
----

After:
[source,xml]
----
<dependency>
<groupId>org.apache.camel</groupId>
<artifactId>camel-test-spring-junit6</artifactId>
<version>${camel.version}</version>
<scope>test</scope>
</dependency>
----
