Camel Spring Boot MockEndpoint assertion not working as expected - spring-boot

My test application can start up normally with CamelSpringBootApplicationController. However, when I am working on the integration test, the assertion of MockEndpoint is not working as expected The snapshot of my test code is listed below. Am I doing anything wrong?
Application.java
#SpringBootApplication
public class Application {
....
public static final String DIRECT_BT_INPUT = "direct:btInput";
public static final String DIRECT_BT_OUTPUT = "direct:btOutput";
#Bean
public RouteBuilder RouteBuilder() {
return new RouteBuilder() {
#Override
public void configure() throws Exception {
from(DIRECT_BT_INPUT).log("${body}").to(DIRECT_BT_OUTPUT);
from(DIRECT_BT_OUTPUT).log("done");
}
};
}
}
BTRouteUnitTest.java
#RunWith(CamelSpringJUnit4ClassRunner.class)
#SpringApplicationConfiguration(classes = Application.class)
#DirtiesContext(classMode = ClassMode.AFTER_EACH_TEST_METHOD)
#MockEndpoints(Application.DIRECT_BT_OUTPUT)
public class BTRouteIT {
#Autowired
protected CamelContext camelContext;
#EndpointInject(uri = "mock:" + Application.DIRECT_BT_OUTPUT)
protected MockEndpoint mockBtOutput;
#Produce(uri = Application.DIRECT_BT_INPUT)
protected ProducerTemplate producerTemplate;
#Test
public void test() throws InterruptedException {
mockBtOutput.expectedBodiesReceived("Hello");
producerTemplate.sendBody("Hello");
MockEndpoint.assertIsSatisfied(camelContext);
}
}

#MockEndpoint is not supported yet in Camel Spring Boot.
Workaround: move endpoint uris to properties file (in route definition use {{}}) and use different property file where you substitute original endpoint uri with mock:orginalUri.

You are testing with CamelSpringJUnit4ClassRunner in camel-test-spring. Camel spring test is for regular spring, not spring-boot.
Use SpringJUnit4ClassRunner test runner instead.

Spring and Camel exlcuding routes in unit tests

I am writing tests for camel in spring boot project, i want to exclude all the routes except the one that i want to test.
So below i want to test the "ftp-poller", i have split the routes into seperate files, but it still loads all the routes, i dont understand is it possible to only load one route or is it becuase they are linked its not possible
#Component
public class FTPRoute extends RouteBuilder {
XmlJsonDataFormat xmlJsonFormat = new XmlJsonDataFormat();
#Override
public void configure() throws Exception {
from("{{endpoint.ftp.server}}")
.id("ftp-poller")
.log("Found file ${file:name}.")
.to("{{endpoint.ftp2.server}}");
from("{{endpoint.ftp2.server}}")
.id("ftp-poller")
.log("Found file ${file:name}.")
.to("{{endpoint.local.validation}}");
}
}
#RunWith(CamelSpringBootRunner.class)
#SpringBootTest(classes = {intTest.class},
properties = { "camel.springboot.java-routes-include-pattern=**/FTPRoute*"})
public class FTPRouteTest {
#Autowired
protected ProducerTemplate producerTemplate;
#EndpointInject(uri = "{{endpoint.requestbin}}")
protected MockEndpoint requestbinEndpoint;
#EndpointInject(uri = "{{endpoint.local.error}}")
protected MockEndpoint localErrorEndpoint;
#Before
public void cleanDir() throws Exception {
deleteDirectory("hb");
}
}

How to test existing camel endpoints with mock?

Im currently working with Camel's mock component and i would like to test it on an existing routes. Basically i want to retain the existing routes defined in the app, but inject a few mocks during test, to verify or at least peek on the current exchange contents.
Based on the docs and from the Apache Camel Cookbook. I've tried to use #MockEndpoints
Here's the route builder
#Component
public class MockedRouteStub extends RouteBuilder {
private static final Logger LOGGER = LoggerFactory.getLogger(MockedRouteStub.class);
#Override
public void configure() throws Exception {
from("direct:stub")
.choice()
.when().simple("${body} contains 'Camel'")
.setHeader("verified").constant(true)
.to("direct:foo")
.otherwise()
.to("direct:bar")
.end();
from("direct:foo")
.process(e -> LOGGER.info("foo {}", e.getIn().getBody()));
from("direct:bar")
.process(e -> LOGGER.info("bar {}", e.getIn().getBody()));
}
}
Here's my test (currently its a springboot project):
#RunWith(SpringRunner.class)
#SpringBootTest
#MockEndpoints
public class MockedRouteStubTest {
#Autowired
private ProducerTemplate producerTemplate;
#EndpointInject(uri = "mock:direct:foo")
private MockEndpoint mockCamel;
#Test
public void test() throws InterruptedException {
String body = "Camel";
mockCamel.expectedMessageCount(1);
producerTemplate.sendBody("direct:stub", body);
mockCamel.assertIsSatisfied();
}
}
message count is 0 and it looks more like #MockEndpoints is not triggered.
Also, logs indicate that the log is triggered
route.MockedRouteStub : foo Camel
An alternative i've tried is to use an advice:
...
#Autowired
private CamelContext context;
#Before
public void setup() throws Exception {
context.getRouteDefinitions().get(0).adviceWith(context, new AdviceWithRouteBuilder() {
#Override
public void configure() throws Exception {
mockEndpoints();
}
});
}
The startup logs indicate that advice is in place:
c.i.InterceptSendToMockEndpointStrategy : Adviced endpoint [direct://stub] with mock endpoint [mock:direct:stub]
But still my test fails with the message count = 0.
Posting the answer which worked for the setup that i have.
Without any changes to the RouteBuilder, the Test would look something like this:
#RunWith(CamelSpringBootRunner.class)
#SpringBootTest
#MockEndpoints
public class MockedRouteStubTest {
#Autowired
private ProducerTemplate producerTemplate;
#EndpointInject(uri = "mock:direct:foo")
private MockEndpoint mockCamel;
#Test
public void test() throws InterruptedException {
String body = "Camel";
mockCamel.expectedMessageCount(1);
producerTemplate.sendBody("direct:stub", body);
mockCamel.assertIsSatisfied();
}
}

Spring Boot Apache Camel Routes testing

I have a Springboot application, where I have some Camel routes configured.
public class CamelConfig {
private static final Logger LOG = LoggerFactory.getLogger(CamelConfig.class);
#Value("${activemq.broker.url:tcp://localhost:61616}")
String brokerUrl;
#Value("${activemq.broker.maxconnections:1}")
int maxConnections;
#Bean
ConnectionFactory jmsConnectionFactory() {
PooledConnectionFactory pooledConnectionFactory = new PooledConnectionFactory(new ActiveMQConnectionFactory(brokerUrl));
pooledConnectionFactory.setMaxConnections(maxConnections);
return pooledConnectionFactory;
}
#Bean
public RoutesBuilder route() {
LOG.info("Initializing camel routes......................");
return new SpringRouteBuilder() {
#Override
public void configure() throws Exception {
from("activemq:testQueue")
.to("bean:queueEventHandler?method=handleQueueEvent");
}
};
}
}
I want to test this route from activemq:testQueue to queueEventHandler::handleQueueEvent.
I tried different things mentioned here http://camel.apache.org/camel-test.html, but doesn't seem to get it working.
I am trying to do something like this:
#RunWith(SpringRunner.class)
#SpringBootTest(classes = {CamelConfig.class, CamelTestContextBootstrapper.class})
public class CamelRouteConfigTest {
#Produce(uri = "activemq:testQueue")
protected ProducerTemplate template;
#Test
public void testSendMatchingMessage() throws Exception {
template.sendBodyAndHeader("testJson", "foo", "bar");
// Verify handleQueueEvent(...) method is called on bean queueEventHandler by mocking
}
But my ProducerTemplate is always null. I tried auto-wiring CamelContext, for which I get an exception saying it cannot resolve camelContext. But that can be resolved by adding SpringCamelContext.class to #SpringBootTest classes. But my ProducerTemplate is still null.
Please suggest. I am using Camel 2.18 and Spring Boot 1.4.
In Camel 2.22.0 and ongoing, which supports Spring Boot 2 you can use the following template to test your routes with Spring Boot 2 support:
#RunWith(CamelSpringRunner.class)
#SpringBootTest(webEnvironment = WebEnvironment.NONE, classes = {
Route1.class,
Route2.class,
...
})
#EnableAutoConfiguration
#DisableJmx
#DirtiesContext(classMode = DirtiesContext.ClassMode.AFTER_CLASS)
public class RouteTest {
#TestConfiguration
static class Config {
#Bean
CamelContextConfiguration contextConfiguration() {
return new CamelContextConfiguration() {
#Override
public void beforeApplicationStart(CamelContext camelContext) {
// configure Camel here
}
#Override
public void afterApplicationStart(CamelContext camelContext) {
// Start your manual routes here
}
};
}
#Bean
RouteBuilder routeBuilder() {
return new RouteBuilder() {
#Override
public void configure() {
from("direct:someEndpoint").to("mock:done");
}
};
}
// further beans ...
}
#Produce(uri = "direct:start")
private ProducerTemplate template;
#EndpointInject(uri = "mock:done")
private MockEndpoint mockDone;
#Test
public void testCamelRoute() throws Exception {
mockDone.expectedMessageCount(1);
Map<String, Object> headers = new HashMap<>();
...
template.sendBodyAndHeaders("test", headers);
mockDone.assertIsSatisfied();
}
}
Spring Boot distinguishes between #Configuration and #TestConfiguration. The primer one will replace any existing configuration, if annotated on a top-level class, while #TestConfiguration will be run in addition to the other configurations.
Further, in larger projects you might run into auto-configuration issues as you can't rely on Spring Boot 2 to configure your custom database pooling or what not correctly or in cases where you have a specific directory structure and the configurations are not located within a direct ancestor directory. In that case it is proabably preferable to omit the #EnableAutoConfiguration annotation. In order to tell Spring to still auto-configure Camel you can simply pass CamelAutoConfiguration.class to the classes mentioned in #SpringBootTest
#SpringBootTest(webEnvironment = WebEnvironment.NONE, classes = {
Route1.class,
Route2.class,
RouteTest.Config.class,
CamelAutoConfiguration.class
}
As no automatic configuration is performed, Spring won't load the test configuration inside your test class nor initialize Camel as well. By adding those configs to the boot classes manually Spring will do it for you.
For one route with MQ and Spring Boot like this:
#Component
public class InboundRoute extends RouteBuilder {
#Override
public void configure() {
JaxbDataFormat personDataFormat = new JaxbDataFormat();
personDataFormat.setContextPath(Person.class.getPackage().getName());
personDataFormat.setPrettyPrint(true);
from("direct:start").id("InboundRoute")
.log("inbound route")
.marshal(personDataFormat)
.to("log:com.company.app?showAll=true&multiline=true")
.convertBodyTo(String.class)
.inOnly("mq:q.empi.deim.in")
.transform(constant("DONE"));
}
}
I use adviceWith in order to replace the endpoint and use only mocks:
#RunWith(CamelSpringBootRunner.class)
#UseAdviceWith
#SpringBootTest(classes = InboundApp.class)
#MockEndpoints("mock:a")
public class InboundRouteCamelTest {
#EndpointInject(uri = "mock:a")
private MockEndpoint mock;
#Produce(uri = "direct:start")
private ProducerTemplate template;
#Autowired
private CamelContext context;
#Test
public void whenInboundRouteIsCalled_thenSuccess() throws Exception {
mock.expectedMinimumMessageCount(1);
RouteDefinition route = context.getRouteDefinition("InboundRoute");
route.adviceWith(context, new AdviceWithRouteBuilder() {
#Override
public void configure() {
weaveByToUri("mq:q.empi.deim.in").replace().to("mock:a");
}
});
context.start();
String response = (String) template.requestBodyAndHeader("direct:start",
getSampleMessage("/SimplePatient.xml"), Exchange.CONTENT_TYPE, MediaType.APPLICATION_XML);
assertThat(response).isEqualTo("DONE");
mock.assertIsSatisfied();
}
private String getSampleMessage(String filename) throws Exception {
return IOUtils
.toString(this.getClass().getResourceAsStream(filename), StandardCharsets.UTF_8.name());
}
}
I use the following dependencies: Spring Boot 2.1.4-RELEASE and Camel 2.23.2. The complete source code is available on Github.
This is how I did this finally:
#RunWith(SpringRunner.class)
public class CamelRouteConfigTest extends CamelTestSupport {
private static final Logger LOG = LoggerFactory.getLogger(CamelRouteConfigTest.class);
private static BrokerService brokerSvc = new BrokerService();
#Mock
private QueueEventHandler queueEventHandler;
#BeforeClass
// Sets up an embedded broker
public static void setUpBroker() throws Exception {
brokerSvc.setBrokerName("TestBroker");
brokerSvc.addConnector("tcp://localhost:61616");
brokerSvc.setPersistent(false);
brokerSvc.setUseJmx(false);
brokerSvc.start();
}
#Override
protected RoutesBuilder createRouteBuilder() throws Exception {
return new CamelConfig().route();
}
// properties in .yml has to be loaded manually. Not sure of .properties file
#Override
protected Properties useOverridePropertiesWithPropertiesComponent() {
YamlPropertySourceLoader loader = new YamlPropertySourceLoader();
try {
PropertySource<?> applicationYamlPropertySource = loader.load(
"properties", new ClassPathResource("application.yml"),null);// null indicated common properties for all profiles.
Map source = ((MapPropertySource) applicationYamlPropertySource).getSource();
Properties properties = new Properties();
properties.putAll(source);
return properties;
} catch (IOException e) {
LOG.error("application.yml file cannot be found.");
}
return null;
}
#Override
protected JndiRegistry createRegistry() throws Exception {
JndiRegistry jndi = super.createRegistry();
MockitoAnnotations.initMocks(this);
jndi.bind("queueEventHandler", queueEventHandler);
return jndi;
}
#Test
// Sleeping for a few seconds is necessary, because this line template.sendBody runs in a different thread and
// CamelTest takes a few seconds to do the routing.
public void testRoute() throws InterruptedException {
template.sendBody("activemq:productpushevent", "HelloWorld!");
Thread.sleep(2000);
verify(queueEventHandler, times(1)).handleQueueEvent(any());
}
#AfterClass
public static void shutDownBroker() throws Exception {
brokerSvc.stop();
}
}
Did you try using Camel test runner?
#RunWith(CamelSpringJUnit4ClassRunner.class)
If you are using camel-spring-boot dependency, you may know that it uses auto configuration to setup Camel:
CamelAutoConfiguration.java
It means that you may also need to add #EnableAutoConfiguration to your test.

#Autowired does not work with #Configurable

I am trying to do an image upload API. I have a ImageUpload task as follows,
#Component
#Configurable(preConstruction = true)
#Scope(BeanDefinition.SCOPE_PROTOTYPE)
public class ImageUploadTask implements Callable<JSONObject> {
#Autowired
private ImageUploadService imageUploadService;
#Override
public JSONObject call() throws Exception {
....
//Upload image via `imageUploadService`
imageUploadService.getService().path('...').post('...'); // Getting null pointer here for imageUploadService which is a WebTarget
}
}
The ImageUploadService looks like the below,
#Component
public class ImageUploadService {
#Inject
#EndPoint(name="imageservice") //Custom annotation, battle tested and works well for all other services
private WebTarget imageservice;
public WebTarget getService() {
return imageservice;
}
}
Here is the spring boot application class,
#ComponentScan
#EnableSpringConfigured
#EnableLoadTimeWeaving(aspectjWeaving=EnableLoadTimeWeaving.AspectJWeaving.ENABLED)
#EnableAutoConfiguration
public class ImageApplication extends SpringBootServletInitializer {
#Bean
public InstrumentationLoadTimeWeaver loadTimeWeaver() throws Throwable {
InstrumentationLoadTimeWeaver loadTimeWeaver = new InstrumentationLoadTimeWeaver();
return loadTimeWeaver;
}
#Override
public void onStartup(ServletContext servletContext) throws ServletException {
super.onStartup(servletContext);
servletContext.addListener(new RequestContextListener());
}
public static void main(String[] args) throws IOException {
SpringApplication.run(ImageApplication.class);
}
}
Additional information :
Spring version of dependencies are at 4.2.5.RELEASE
pom.xml has dependencies added for spring-aspects and
spring-instrument
I am getting a NullPointerException in ImageUploadTask. My suspicion is that #Autowired doesn't work as expected.
Why wouldn't work and how do I fix this?
Is it mandatory to use #Autowired only when I use #Conigurable, why not use #Inject? (though I tried it and getting same NPE)
By default the autowiring for the #Configurable is off i.e. Autowire.NO beacuse of which the imageUploadService is null
Thus update the code to explicity enable it either as BY_NAME or BY_TYPE as below.
#Component
#Configurable(preConstruction = true, autowire = Autowire.BY_NAME)
#Scope(BeanDefinition.SCOPE_PROTOTYPE)
public class ImageUploadTask implements Callable<JSONObject> { .... }
Rest of the configuration viz. enabling load time weaving seems fine.
Also regarding #Inject annotation have a look here which pretty much explains the difference (or similarity perhaps)

Using test application.properties file with CamelSpringTestSupport in Spring Boot

Prerequisites
Apache Tomcat 7
Spring 4.1.5.RELEASE
Spring Boot 1.2.2.RELEASE
Apache Camel 2.15.1
Problem
I am Using Spring Boot with a configuration class which is also used by EndpointSetup.
#SpringBootApplication
#Import({MyConfiguration.class, EndpointSetup.class})
public class MyFatJarRouter extends FatJarRouter { ... }
#Configuration
#ConfigurationProperties(prefix = "camel.route", ignoreUnknownFields = false)
public class MyConfiguration {
private List<String> brokerUrl = new ArrayList<>();
public List<String> getBrokerUrl() {return brokerUrl;}
public void setBrokerUrl(List<String> brokerUrl) {this.brokerUrl = brokerUrl;}
}
In production properties will be read from conf/application.properties by default.
I want to test my routes via CamelSpringTestSupport
So I have tried following:
I have placed a application.properties under test/resources/config/application.properties (--> in classpath of test)
then wrote following:
public class MyJmsTest extends CamelSpringTestSupport {
#Override
protected AbstractApplicationContext createApplicationContext() {
return new AnnotationConfigApplicationContext(MyFatJarRouter.class);
}
#Test
public void myTest() throws Exception {
...
}
}
In the example above the configuration is not read from the application.properties placed in test folder.
How can I read a test specific config file in my CamelSpringTestSupport Unit-Test?
I may be little late in answering, but there is a better way than hacking endpoints. The following solution uses toD introduced in Camel 2.16. I wrote a custom component "github" (there's an official one as well), and the following is how I test it. Note that I'm not using a single Camel proprietary annotation. To inject properties, I can either use the properties attribute in #SpringBootTest, or any of the other standard techniques available in Spring Boot.
Note that I'm using $simple{...} to avoid clash with Spring property resolution.
<rant>
And yes, Camel documentation sucks! They write it like release notes, with a section dedicated to each release, and don't seem to update the doc to keep up with the latest versions (the following technique is not documented). Imagine going to a restaurant and asking for the special, only to be told by the server about the special for the day before, and the week before, and so on. How about versioning the doc instead?

private GitHubClient gitHubClient;

public void testGitHubClientInvoked() throws InterruptedException {

I solved it by using standard spring unit-tests like this:
#RunWith(SpringJUnit4ClassRunner.class)
#SpringApplicationConfiguration(classes = Application.class)
#ActiveProfiles("test") // Load applicaton-test.properties in test/resources/config/application-test.properties
#DirtiesContext(classMode = DirtiesContext.ClassMode.AFTER_EACH_TEST_METHOD) // cleanup spring context because jms broker does not exit properly
public class MyJmsTest {
private static final String MOCK_MY_ENDPOINT = "mock:myEndpoint";
#Autowired
CamelContext context;
#Autowired
ApplicationContext applicationContext;
#Autowired
ProducerTemplate producerTemplate;
#Before
public void configureMocks() throws Exception {
context.getRouteDefinition("MyRoute")
.adviceWith(context, new AdviceWithRouteBuilder() {
#Override
public void configure() throws Exception {
weaveByToString(".*myEndPointId.*")
.replace()
.to(MOCK_MY_ENDPOINT);
}
});
final MockEndpoint endpoint = context.getEndpoint(MOCK_MY_ENDPOINT, MockEndpoint.class);
endpoint.whenAnyExchangeReceived(new Processor() {
#Override
public void process(Exchange exchange) throws Exception {
InputStream inStream = getClass().getClassLoader().getResourceAsStream("xml/my.xml");
String in = context.getTypeConverter().convertTo(String.class, inStream);
exchange.getIn().setBody(in);
}
});
}
#Test
public void synchronousCallBasic_1() throws Exception {
final MyConfiguration MyConfiguration = applicationContext.getBean(MyConfiguration.class);
final String myMessageBody =
context.getTypeConverter().convertTo(String.class, getClass().getClassLoader()
.getResourceAsStream("xml/0010_example.xml"));
final Object myResult = producerTemplate.requestBody(MyConfiguration.getActiveMqSynchronousEndpointUri(), myMessageBody);
assertThat(myResult, notNullValue());
assertThat((String)myResult, is("<example>1</example>"));
}
}
I solved this issue, with a lot of annotation which I found here, and now the test properties are correctly injected:
#RunWith(CamelSpringBootRunner.class)
#SpringBootTest
#ActiveProfiles("test")
#EnableAutoConfiguration
#ComponentScan
#ContextConfiguration()
public class MessageDeliveryTest{
}
Also, the test properties file needs to be named application-{env}.properties, where "env" is the profile used here. For eg. for test the properties file should be application-test.properties
