How to load many classes in the TestFramework ?

We have such a possibility internally but this is not open unfortunately.

Question:

How to "load" additional (non-inner) classes in the system, that you
could later retrieve with findClass.

My goal :

I want to load fake
org.apache.log4j.Logger
org.apache.log4j.Level
org.apache.log4j.Category

Any hope you would open it soon?

The only trick I've found is to use inner classes, but it's butt-ugly,
and not really what I seek.

Well, I spoke too fast : inner classes don't seem to work in the -
public version of the - test framework :

InheritanceUtil.isInheritorOrSelf(innerClass, outerClass, true);

generates an odd stacktrace :

isInheritor 1 = true
isInheritor 2 = true

java.lang.NoClassDefFoundError:
org/apache/tools/ant/filters/StringInputStream
at java.lang.Class.forName0(Native Method)
at java.lang.Class.forName(Class.java:141)
...

(see the code below)


Too bad, back to the old, pre-testframework darkage days.

Gosh.

Hi Alain!

Please send us a full stacktrace. It seems that ant.jar in your tests
classpath could help. But to be sure I need detailed stacktrace or your
utility classes.

Thanks,

Duh. Shame on me. Of course it helped.

Anyway, here is the full stacktrace, in case it's still useful to you.
