Thanks for your advice. Here's my attempt to modify my test to use
CamelSpringJUnit4ClassRunner and annotations to mock my SQL endpoint.
@RunWith(CamelSpringJUnit4ClassRunner.class)
@ContextConfiguration(classes = CamelConfig.class)
@DirtiesContext(classMode = DirtiesContext.ClassMode.AFTER_EACH_TEST_METHOD)
@MockEndpoints("sql:*")
public class FooRouteTests {
@Autowired
CamelContext camelContext;
@Produce
ProducerTemplate template;
@EndpointInject(uri = "mock:sql:*")
MockEndpoint mockSql;
@Test
public void testMockSQLEndpoint() throws Exception {
template.sendBody("direct:foo", "bar");
mockSql.expectedMessageCount(1);
// todo: take input message and return mock results
(ArrayList<HashMap>)
MockEndpoint.assertIsSatisfied(camelContext);
}
}
For some reason, this results in an error, even though my CamelConfig works for
configuring other tests.
Could not autowire field: org.apache.camel.CamelContext
com.company.app.foo.FooRouteTests.camelContext; nested exception is
org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying
bean of type [org.apache.camel.CamelContext] found for dependency: expected at
least 1 bean which qualifies as autowire candidate for this dependency.
@Configuration
@ImportResource("classpath:META-INF/cxf/cxf.xml")
@ComponentScan("com.company.app")
public class CamelConfig extends CamelConfiguration {
@Override
protected void setupCamelContext(CamelContext camelContext) throws
Exception {
PropertiesComponent pc = new PropertiesComponent();
pc.setLocation("classpath:application.properties");
camelContext.addComponent("properties", pc);
super.setupCamelContext(camelContext);
}
}
