AbstractSpringAction Test Case available?

[colletts]

Hi,

Are there any Junit helper classes for creating test cases for AbstractSpringAction(s)?

I am looking for something along the lines of spring classes like AbstractDependencyInjectionSpringContextTests.

Failing that are there any good examples of using Junit to test JBoss ESB actions?

I tried to create an AbstractSpringAction and ConfigTree programatically in the testcase but I can't seem to get the Spring Container to initialise in a junit test.

Test Class

public class MySpringEnabledActionTest extends AbstractDependencyInjectionSpringContextTests{


 public void testSayHelloAopStyle() throws Exception {

 String messageObject = "Message Body String Object";

 Message esbMessage = MessageFactory.getInstance().getMessage();

 esbMessage.getBody().add(messageObject);

 Message returnMessage;

 File esbConfigFile = new File("C:/dev/workspace/TestJBossESBSpringAOP/src/main/resources/META-INF/jboss-esb.xml");

 FileInputStream fis = new FileInputStream(esbConfigFile);

 ConfigTree configTree = ConfigTree.fromInputStream(fis);

 MySpringEnabledAction mySpringEnabledAction = new MySpringEnabledAction(configTree);

 returnMessage = mySpringEnabledAction.sayHelloAopStyle(esbMessage);

 assertSame(messageObject,returnMessage.getBody().get());

 }

 ...
}

this works to a point; but in the actual AbstractSpringAction the spring bean factory is not initialised.

 public class MySpringEnabledAction extends AbstractSpringAction
 {


 public MySpringEnabledAction(ConfigTree config) throws Exception
 {
 configTree = config;
 }

 public Message sayHelloAopStyle(Message message) throws Exception
 {


 String springContextXml = configTree.getAttribute("springContextXml");

 logger.error("springContextXml from contextTree is " + springContextXml); \\ shows that the springContextXml attribute is null


 BeanFactory beanFactory = getBeanFactory();

 if (beanFactory==null){
 logger.error("Beanfactory is null"); \\ because the springContext is null the beanfactory is null??
 } else{
 logger.error("Beanfactory is NOT null");
 }

 SaySomething hello = (SaySomething) beanFactory.getBean("helloObject"); \\null pointer exception here

 logHeader();
 // interceptor will get applied here
 // check the console output to see the interceptor changed the message

 hello.setGreeting((String)message.getBody().get());


 logFooter();

 return message;
 }

The jboss-esb.xml is exactly the same as from the sample quickstart spring_aop i.e. there is a springContextXml attribute pointing to the spring-context.xml

Using jbossesb-server-4.2.1GA in windows XP win32 with Eclipse 3.3.1.1 and Maven 2.0 running the test cases


Thanks

If you're looking for Junit tests in general, have a look at the ESB source: it comes with quite a few in there that test all aspects of the ESB as well as the actions. There are some Spring based ones in there too.

Thanks for that tip

I found a Junit test in

\jbossesb-4.2.1GA-src\product\services\spring\src\test\java\org\jboss\soa\esb\actions\spring\AbstractSpringActionUnitTest.java


To fix my original test I needed to explicity set the springContextXml attribute of the configTree after i created it and run the .initialise() method on the instance of the AbstractSpringAction again after i created it in the unit test.

Modified MySpringEnabledActionTest

public class MySpringEnabledActionTest extends
AbstractDependencyInjectionSpringContextTests{

 private static Logger logger = Logger.getLogger(MySpringEnabledActionTest.class);

 public void testSayHelloAopStyle() throws Exception {

 String messageObject = "MySpringEnabledActionTest Message Body String Object";

 Message esbMessage = MessageFactory.getInstance().getMessage();

 esbMessage.getBody().add(messageObject);

 Message returnMessage;

 File esbConfigFile = new File("C:/dev/workspace/TestJBossESBSpringAOP/src/main/resources/META-INF/jboss-esb.xml");

 logger.error("Config File exists " + esbConfigFile.exists());

 FileInputStream fis = new FileInputStream(esbConfigFile);

 ConfigTree configTree = ConfigTree.fromInputStream(fis);

 logger.error("springContextXml is " + configTree.getAttribute("springContextXml"));

 logger.error("Setting springContextXml explictly ");

 // Added explicity setting of springContextXml attribute of the ConfigTree
 configTree.setAttribute("springContextXml","/spring-context.xml");

 logger.error("springContextXml is " + configTree.getAttribute("springContextXml"));

 MySpringEnabledAction mySpringEnabledAction = new MySpringEnabledAction(configTree);

 // Added explicit call to initialise the AbstractSpringAction - this loads spring container
 mySpringEnabledAction.initialise();

 returnMessage = mySpringEnabledAction.sayHelloAopStyle(esbMessage);

 logger.error("ReturnMessage " + returnMessage.getBody().get());

 ...

 }
