Question

I have a list of jar files, all containing slightly different versions of the same system.

I want to execute a set of test cases on each jar file while being able to obtain the results for each jar (via RunListener or something like that).

I am a bit confused with the class loading problems that are implied.

How can I nicely do this ?

If you are using ant, the JUnit task takes a classpath.

<target name='test'>   <junit ...'>     <classpath>       <pathelement path='${test.jar.path}' />     </classpath>     ...   </junit> </target> 

You can use the antcall task to call your test target repeatedly with a differed value for the test.jar.path property.
