AOP Test support

[adrian.brock]

I want to write some test support for aop.

This will be similar to what I did for the MC where
it looks for configuration like the test name.

e.g.
org.jboss.test.aop.foo.Bar.class
will use
/org/jboss/test/aop/foo/Bar-aop.xml

I've wasted most of today trying to figure out a way to
customize classloading so it will work in Junit inside Eclipse.

This looks like an impossible task. Basically, I need a mechanism
to either install an agent or insert my own classloader so
I can intercept defineClass() and pass it to AOP.

The two best solutions are:

* Something AntClassLoader which "hides" part of the classpath
so you can create a custom classloader to load the rest of the classpath.
But there is no portable mechanism to determine which parts of the
classpath are from the jre and which are in the classpath.

* Forking off a process to run the junit tests and using a remote
test runner similar to EJBUnit.
But this is a bit convulted.

Given that failed, what is your preferred mechanism for
configuring JBossAOP when running it from the command line?

There are a lot of choices :-)

Assuming that loadtime is what you want, the preferred is to use the -javaagent with JDK 5 and -Xbootclasspath on JDK 1.4

To debug in eclipse:
http://wiki.jboss.org/wiki/Wiki.jsp?page=DebuggingJBossAOPInEclipse

To do loadtime (with JDK 5) in Eclipse add this to the vm arguments:
-javaagent:/some/where/jboss-aop-jdk50.jar

I went for the System classloader since I want these tests
to run in JDK1.4 and -Xbootclasspath is not portable either.

The MicrocontainerAOP smoke test is failing because of an
invalid assumption:
