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.
