Test

Since Camel 2.9

The camel-test module is used for unit testing Camel.

The class org.apache.camel.test.junit4.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. 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.test.junit4.CamelTestSupport;
import org.junit.Test;

public class SimpleMockTest extends CamelTestSupport {

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

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

        assertMockEndpointsSatisfied();
    }

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

}
