CamelTestSupport problem
edevera Jul 13, 2012 10:56 AMI am trying to test my camel route builder (which contains endpoints with switchyard as a component) based on the CamelTestSupport class that looks like this:
import org.edevera.model.Entity; import org.apache.camel.*; import org.apache.camel.builder.RouteBuilder; import org.apache.camel.component.properties.PropertiesComponent; import org.apache.camel.model.ProcessorDefinition; import org.apache.camel.test.junit4.CamelTestSupport; import org.junit.Test; /** * @author: Eduardo de Vera * Date: 6/29/12 * Time: 12:41 AM */ public class MyRouterBuilderTest extends CamelTestSupport { @EndpointInject(uri=MyRouteBuilder.ENDPOINT_MY_SERVICE) private ProducerTemplate producerTemplate; protected RouteBuilder createRouteBuilder() throws Exception { return new MyRouteBuilder(); } @Test public void testSendEntityAndSave() throws InterruptedException { Entity body = new Entity(); producerTemplate.sendBodyAndHeader(body, "operation", "save"); Thread.sleep(1000); assertTrue(true); } protected CamelContext createCamelContext() throws Exception { CamelContext context = super.createCamelContext(); //Preparing properties PropertiesComponent prop = context.getComponent("properties", PropertiesComponent.class); prop.setLocation("classpath:router.properties"); // Substituting switchyard component for a seda. return context; } @Override protected void debugBefore(Exchange exchange, Processor processor, ProcessorDefinition definition, String id, String label) { System.out.println("Id:" + id + ", Label:" + label); } } {code} and I run into the following problem: {code} org.apache.camel.CamelExecutionException: Exception occurred during execution on the exchange: Exchange[Message: 0-null|] at org.apache.camel.util.ObjectHelper.wrapCamelExecutionException(ObjectHelper.java:1237) at org.apache.camel.util.ExchangeHelper.extractResultBody(ExchangeHelper.java:509) at org.apache.camel.impl.DefaultProducerTemplate.extractResultBody(DefaultProducerTemplate.java:442) at org.apache.camel.impl.DefaultProducerTemplate.extractResultBody(DefaultProducerTemplate.java:438) at org.apache.camel.impl.DefaultProducerTemplate.sendBodyAndHeader(DefaultProducerTemplate.java:152) at org.apache.camel.impl.DefaultProducerTemplate.sendBodyAndHeader(DefaultProducerTemplate.java:354) at com.edevera.services.MyRouterBuilderTest.testSendEntityAndSave(MyRouterBuilderTest.java:28) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) at org.junit.runners.model.FrameworkMethod$1.runReflectiveCall(FrameworkMethod.java:45) at org.junit.internal.runners.model.ReflectiveCallable.run(ReflectiveCallable.java:15) at org.junit.runners.model.FrameworkMethod.invokeExplosively(FrameworkMethod.java:42) at org.junit.internal.runners.statements.InvokeMethod.evaluate(InvokeMethod.java:20) at org.junit.internal.runners.statements.RunBefores.evaluate(RunBefores.java:28) at org.junit.internal.runners.statements.RunAfters.evaluate(RunAfters.java:30) at org.junit.rules.TestWatcher$1.evaluate(TestWatcher.java:47) at org.junit.rules.RunRules.evaluate(RunRules.java:18) at org.junit.runners.ParentRunner.runLeaf(ParentRunner.java:263) at org.junit.runners.BlockJUnit4ClassRunner.runChild(BlockJUnit4ClassRunner.java:68) at org.junit.runners.BlockJUnit4ClassRunner.runChild(BlockJUnit4ClassRunner.java:47) at org.junit.runners.ParentRunner$3.run(ParentRunner.java:231) at org.junit.runners.ParentRunner$1.schedule(ParentRunner.java:60) at org.junit.runners.ParentRunner.runChildren(ParentRunner.java:229) at org.junit.runners.ParentRunner.access$000(ParentRunner.java:50) at org.junit.runners.ParentRunner$2.evaluate(ParentRunner.java:222) at org.junit.internal.runners.statements.RunAfters.evaluate(RunAfters.java:30) at org.junit.runners.ParentRunner.run(ParentRunner.java:300) at org.junit.runner.JUnitCore.run(JUnitCore.java:157) at com.intellij.junit4.JUnit4IdeaTestRunner.startRunnerWithArgs(JUnit4IdeaTestRunner.java:76) at com.intellij.rt.execution.junit.JUnitStarter.prepareStreamsAndStart(JUnitStarter.java:195) at com.intellij.rt.execution.junit.JUnitStarter.main(JUnitStarter.java:63) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39) at com.intellij.rt.execution.application.AppMain.main(AppMain.java:120) Caused by: java.lang.NullPointerException at org.switchyard.component.camel.SwitchYardProducer.lookupServiceReference(SwitchYardProducer.java:94) at org.switchyard.component.camel.SwitchYardProducer.process(SwitchYardProducer.java:80) at org.apache.camel.util.AsyncProcessorConverterHelper$ProcessorToAsyncProcessorBridge.process(AsyncProcessorConverterHelper.java:61) at org.apache.camel.processor.UnitOfWorkProcessor.processAsync(UnitOfWorkProcessor.java:150) at org.apache.camel.processor.UnitOfWorkProcessor.process(UnitOfWorkProcessor.java:117) at org.apache.camel.util.AsyncProcessorHelper.process(AsyncProcessorHelper.java:99) at org.apache.camel.processor.DelegateAsyncProcessor.process(DelegateAsyncProcessor.java:86) at org.apache.camel.processor.UnitOfWorkProducer.process(UnitOfWorkProducer.java:63) at org.apache.camel.impl.ProducerCache$2.doInProducer(ProducerCache.java:352) at org.apache.camel.impl.ProducerCache$2.doInProducer(ProducerCache.java:324) at org.apache.camel.impl.ProducerCache.doInProducer(ProducerCache.java:223) at org.apache.camel.impl.ProducerCache.sendExchange(ProducerCache.java:324) at org.apache.camel.impl.ProducerCache.send(ProducerCache.java:169) at org.apache.camel.impl.DefaultProducerTemplate.send(DefaultProducerTemplate.java:111) at org.apache.camel.impl.DefaultProducerTemplate.sendBodyAndHeader(DefaultProducerTemplate.java:150) ... 33 more
Can anyone help me out on this one? I tried using SwitchyardRunner based tests but I can't manage to obtain a reference to the different components that interact during an exchange (as explained here: https://community.jboss.org/thread/202157?tstart=0), so I am trying to at least test the Camel Route Builder.
