[jboss-user] [JBoss AOP] - Different jboss-aop.xml files for unit testing

[nizzy]

Hi All,

As mentioned in my previous post I'm reviewing AOP for use with unit testing.

I define my jboss-aop.xml in test/META-INF folder in my eclipse project. I have noticed that it is going to be quite probable that poincut definitions are going to cause undesired side-effects.

For instance - if you consider the test code


  | @Test
  |     public void testCreateObject() {
  |         try {
  |             man.createObject(ap);
  |         } catch (Exception e) {
  |             fail("Test failed since exception was thrown: " + e);
  |         }
  |     }
  |     
  |     @Test
  |     public void testCreateObject_MultefileException() {
  |         try {
  |             man.createObject(ap);
  |             fail("Should have thrown MultefileException");
  |         } catch (Exception e) {
  |             
  |             if (!(e instanceof MultefileException)) {
  |                 fail("Test failed since exception was not MultefileException: " + e);
  |             } 
  |         }
  |     }

then the jboss-aop.xml


  | 	<bind pointcut="execution(public $typedef{persistenceHelperTypeDef}->new(java.lang.String))">
  |        <interceptor class="com.ecebs.unittest.aop.interceptor.GenericInterceptor">
  |            <attribute name="mockObjectName">MockPersistenceHelper</attribute>
  |        </interceptor>
  |     </bind>
  | 
  |     <typedef name="persistenceHelperTypeDef" 
  |             expr="class($instanceof{com.ecebs.unittest.aop.IPersistenceHelper}) 
  |             		AND !class(com.ecebs.unittest.aop.mock.*)" />
  |             		
  |     <aspect class="com.ecebs.unittest.aop.aspect.ExceptionInjector" />
  |     <bind pointcut="execution(public void com.ecebs.unittest.aop.AOPUnitTestManagerBean->createObject(..))">
  |     	<advice name="throwMultefileException" aspect="com.ecebs.unittest.aop.aspect.ExceptionInjector" />
  |     </bind>

The first entry in the jboss-aop.xml file mocks-out a persistence helper.

The createObject test would then pass. When I add the subsequent aspect and bind to inject an Exception - every time createObject is called - the first test obviously then fails - which I appreciate is exactly what I would expect to happen given the way I have set this up!!

Is there a way; via the pointcut definitions or by changing which jboss-aop.xml file is used, to overcome such an issue?
