Simple Testing• You need the camel-test module• Your test should extend the CamelTestSupport class and…• Typically you will need to override the createRouteBuilder() method• JNDI Registry

Spring Testing• You need the camel-test-spring module• Use the @RunWith(SpringJUnit4ClassRunner.class) annotation• Provide your configuration using an XML file…

– src/test/java/org/istabg/camel/examples/SpringFilterTest.java– src/test/java/org/istabg/camel/examples/SpringFilterTest-context.xml

• or use the Java DSL with a configuration loader

Live Demo

Blueprint Testing• You need the camel-test-blueprint module• Your test should extend the CamelBlueprintTestSupport class and…• Specify the Blueprint descriptor location

http://camel.apache.org/blueprint-testing.html

Live Demo
