Kamil created CAMEL-11687:
-----------------------------
Summary: Camel-spring-boot documentation should also cover testing
Key: CAMEL-11687
URL: https://issues.apache.org/jira/browse/CAMEL-11687
Project: Camel
Issue Type: Improvement
Components: camel-spring-boot
Reporter: Kamil
The [Documentation|http://camel.apache.org/spring-boot.html] helps a lot with
configuring Camel with SpringBoot but says nothing about how to configure
tests, which is not trivial...
First of all I noticed, that when you don't Autowire CamelContext and return it
in:
{code}
@Override
protected CamelContext createCamelContext() throws Exception {
return camelContext;
}
{code}
you end up in having two contexts, which causes for example that exception:
{code}

Also "CamelSpringTestSupport" requires you to implement
"createApplicationContext()" which is weird.
To sum it up - I found this configuration working fine with Camel-spring-boot:
{code}
@ActiveProfiles("test")
@RunWith(CamelSpringBootRunner.class)
@SpringBootTest
@DirtiesContext(classMode = ClassMode.AFTER_EACH_TEST_METHOD)
@DisableJmx(true)
public class MyRouteTest extends CamelTestSupport {
@Autowired
private CamelContext camelContext;
@Override
protected CamelContext createCamelContext() throws Exception {
return camelContext;
}
@EndpointInject(uri = "direct:myEndpoint")
private ProducerTemplate endpoint;
@Override
public void setUp() throws Exception {
super.setUp();
RouteDefinition definition =
context().getRouteDefinitions().get(0);
definition.adviceWith(context(), new RouteBuilder() {
@Override
public void configure() throws Exception {
onException(Exception.class).maximumRedeliveries(0);
}
});
}
@Override
public String isMockEndpointsAndSkip() {
return "myEndpoint:put*";
}
@Test
public void shouldSucceed() throws Exception {
assertNotNull(camelContext);
assertNotNull(endpoint);
String expectedValue = "expectedValue";
MockEndpoint mock = getMockEndpoint("mock:myEndpoint:put");
mock.expectedMessageCount(1);
mock.allMessages().body().isEqualTo(expectedValue);
mock.allMessages().header(MY_HEADER).isEqualTo("testHeader");
endpoint.sendBodyAndHeader("test", MY_HEADER, "testHeader");
mock.assertIsSatisfied();
}
}
{code}
