Name | Component | Description |
|---|---|---|
| Is a standalone Java library letting you easily create Camel test cases using a single Java class for all your configuration and routing without using Spring or Guice for Dependency Injection which does not require an in-depth knowledge of Spring + Spring Test or Guice. Supports JUnit 3.x (deprecated) and JUnit 4.x based tests. | |
| CDI Testing | camel-test-cdi | Provides a JUnit 4 runner that bootstraps a test environment using CDI so that you don't have to be familiar with any CDI testing frameworks and can concentrate on the testing logic of your Camel CDI applications. Testing frameworks like Arquillian or PAX Exam, can be used for more advanced test cases, where you need to configure your system under test in a very fine-grained way or target specific CDI containers. |
| Supports JUnit 3.x (deprecated) or JUnit 4.x based tests that bootstrap a test environment using Spring without needing to be familiar with Spring Test. The plain JUnit 3.x/4.x based tests work very similar to the test support classes in | |
| Camel 2.10: Provides the ability to do unit testing on blueprint configurations | |
| Uses Guice to dependency inject your test classes | |
Camel TestNG |
| Supports plain TestNG based tests with or without Spring or Guice for Dependency Injection which does not require an in-depth knowledge of Spring + Spring Test or Guice. Also from Camel 2.10 onwards, this component supports Spring Test based tests that use the declarative style of test configuration and injection common in Spring Test and described in more detail under Spring Testing. |

CamelTestSupport but has no Spring or Guice dependency injection configuration but instead overrides the createRouteBuilder() method.Spring Test with XML Config Example

@DirtiesContext on the test methods to force Spring Testing to automatically reload the CamelContext after each test method - this ensures that the tests don't clash with each other (e.g. one test method sending to an endpoint that is then reused in another test method).Also notice the use of @ContextConfiguration to indicate that by default we should look for the FilterTest-context.xml on the classpath to configure the test case which looks like this:

ContextConfig class does all of the configuration; so your entire test case is contained in a single Java class. We currently have to reference by class name this class in the @ContextConfiguration which is a bit ugly. Please vote for SJC-238 to address this and make Spring Test work more cleanly with Spring JavaConfig.Its totally optional but for the ContextConfig implementation we derive from SingleRouteCamelConfiguration which is a helper Spring Java Config class which will configure the CamelContext for us and then register the RouteBuilder we create.
Since Camel 2.11.0 you can use the CamelSpringJUnit4ClassRunner with CamelSpringDelegatingTestContextLoader like example using Java Config with CamelSpringJUnit4ClassRunner:

Here is a Camel test support enhanced Spring Testing example using XML Config and pure Spring Test based configuration of the Camel Context:

@RunWith annotation to support the features of CamelTestSupport through annotations on the test class. See See Spring Testing for a list of annotations you can use in your tests....
