Test JUnit6

Since Camel 4.17

The camel-test-junit6 module is used for unit testing Camel with JUnit 6.

The class org.apache.camel.test.junit6.CamelTestSupport provides a base JUnit class which you would extend and implement your Camel unit test.

Simple unit test example

As shown below is a basic junit test which uses camel-test-junit6. The createRouteBuilder method is used for build the routes to be tested. Then the methods with @Test annotations are JUnit test methods which will be executed. The base class CamelTestSupport has a number of helper methods to configure testing, see more at the Javadoc of this class.

import org.apache.camel.RoutesBuilder;
import org.apache.camel.builder.RouteBuilder;
import org.apache.camel.component.mock.MockEndpoint;
import org.apache.camel.test.junit6.CamelTestSupport;
import org.junit.jupiter.api.Test;

public class SimpleMockTest extends CamelTestSupport {

    @Test
    public void testMock() throws Exception {
        getMockEndpoint("mock:result").expectedBodiesReceived("Hello World");

        template.sendBody("direct:start", "Hello World");

        MockEndpoint.assertIsSatisfied(context);
    }

    @Override
    protected RoutesBuilder createRouteBuilder() {
        return new RouteBuilder() {
            @Override
            public void configure() {
                from("direct:start").to("mock:result");
            }
        };
    }

}

Migrating Camel Tests from JUnit 5 to JUnit 6

Find below some hints to help in migrating camel tests from JUnit 5 to JUnit 6.

Projects using camel-test-junit5 would need to use camel-test-junit6. For instance, maven users would update their pom.xml file as below:

<dependency>
  <groupId>org.apache.camel</groupId>
  <artifactId>camel-test-junit6</artifactId>
  <scope>test</scope>
</dependency>

Migration Steps

Imports of org.apache.camel.test.junit5.* should be replaced with org.apache.camel.test.junit6.*

Please check the JUnit User Guide for additional insights about migrating to and writing tests using JUnit 6.
